SCP-507/Synopsis

The history and its interpretations of SCP-507.
==Background==
SCP-507 started out as a normal human named either John or Thomas Yaltz, having a mother who he loved dearly and lived mostly a normal life. Eventually, he gained a loving girlfriend who, despite being teased for dating a fat pathetic loser like 507, remained by his side. One day, they went to the beach to hang out, but because of his clumsiness they got embarrassed, causing them to go for a walk to get out of people's sight. However, while walking, SCP-507 suddenly teleported to a cold forest at nighttime. Confused, 507 told his girlfriend to hold his hand so they would return together. Unfortunately, laughter was soon heard, frightening his girlfriend who ran away which led to her death. In the aftermath of this incident, 507 was locked in a unknown asylum.
SCP-507 was contained following reports of an individual repeatedly escaping from the asylum as witnesses described seeing bright flashes of light before noticing that SCP-507 was missing. Following these reports, the SCP Foundation eventually contained SCP-507 under the designation that he was "being moved to a more secure facility". He was classified as Safe and was allowed to freely roam the facility in which he was contained, albeit always accompanied by an agent and equipped with a tracking device. He was also given a computer with internet connection, but with a proxy that limited the information exchange, and he could meet fellow Safe or Euclid SCPs, such as SCP-082 and presumably even SCP-076-2, as during his time under containment he gained the Foundation's trust.
==Interdimensional Travels==
While under the custody of the Foundation, 507 would suddenly against his will travel to random different realities and once teleporting back he would go back to the Foundation or be relocated by them. In his first trip, SCP-507 found himself in a place shrouded in complete darkness. After wondering around awhile, he began to hear a strange breathing sound within close proximity, causing him to panic and curl up in fear, before suddenly returning to the current reality. Following this incident, SCP-507 now carried a flashlight at all times.
In his second trip, SCP-507 teleported to a replica of the Foundation facility in which he was contained, but in disarray. As he explored her came across various decaying corpses covered in a strange mold, which apparently was created from SCP-407, strewn across the building. However, he soon noticed that corpses were still breathing and immediately attempted to exit only to find out the outside world had been coated in the same mold. Luckily, at that moment he returned to the Foundation and requested for a check up, but thankfully he was in good health. In his third trip, SCP-507 arrived to a world inhabited by countless spiders and after returning he requested a gun for self-defense, which was granted but only to shoot rubber bullets.
He eventually returned to the place he had been in his first trip, finding the breathing noise had returned. When he activated his flashlight to discover the breathing's origin, he found himself face-to-face with a man resembling a Men in Black, wearing a black business suit and black sunglasses. SCP-507 described the man as having an unnaturally wide smile, and that he was leaning in towards SCP-507. Upon nearly touching him, the "Smiling Man" remarked "Back so soon?". Frightened, SCP-507 switched off his flashlight and began firing his handgun until he consumed all the ammo; he then curled in fear just like the previous trip before returning once more to the current reality.
While in the company of an agent the latter put his hand on SCP-507's shoulder and in that exact moment he shifted to an hostile environment along with the agent. During the chaos, 507 was separated from the agent and was unable to find him, causing to return back alone. A week later he was found by the Foundation and explained to them what had transpired, leading to the formation of a new protocol that allowed staff to interact with him only for a short period of time after his latest shift.
In his sixth trip, SCP-507 went to desert environment where he eventually came across an impoverished man. The man was surprised to find 507, but nonetheless asked him to follow him back to a shelter where he could eat. SCP-507 obliged and started following the man, until noticing that his leather jacket was covered in stitches, meaning that the man was probably a cannibal who used his victims' skin to make clothes. Thankfully, 507 returned to his home reality soon after.
In his seventh trip, SCP-507 arrived to a forest habitat completely devoid of human influence. Some time wandering through the area, 507 grew hungry and tried to eat a local fruit, only for the plant life to telepathically scream at him, causing him to stop what he was doing. However, the following days, the hunger got the better of him and went on to eat the fruits, ignoring the screams which made him feel terrible. After returning, 507 began eating mostly gelatin and pudding for some weeks.
In his eighth trip, SCP-507 was transported to an alternate universe which was the same as his, with the main exception being that the population's genders were switched. There he encountered his counterpart, and to his shock despite this version being a woman she looked almost exactly like him. In his fourth trip, 507 went to a unknown dimension which he could only describe as nowhere and while there he lost track of time, apparently due to that reality lacking existence. After returning he was given a ticking wristwatch.
In his ninth trip, while sleeping in his quarters SCP-507 arrived to an alternate universe where he was still a patient at the asylum. Because of this, he was restrained with a straitjacket and bound to his bed due to the staff believing he was in the advanced stages of dementia, and as a result he was sedated which caused him to feel drowsy until returning. He was left still trapped in the straitjacket and leg restrains for some time before personnel found him and help him free himself. In the tenth trip, he was teleported back to the forest which appeared to remember him as it telepathically screamed at him during the entire stay. After returning, the experience left him upset and was granted a hug by the sympathetic personnel. It is completely unknown what happened in his eleventh trip as the O5 Council prevented any personnel with a level clearance lower than Level 5 from learning of it.
In his twelfth trip, SCP-507 was teleported in a metropolitan area completely devoid of human life but filled with cats. As per usual, he wandered through the environment, coming across countless cats some of which he petted. Coming back shortly after, the personnel found a deadly variant of the Toxoplasma gondii cat parasite which had apparently eradicated humanity in the other universe, but thankfully he didn't contract Toxoplasmosis. Afterwards, all of his clothes and belongings were incinerated and he was forced to undergo decontamination, but when he requested a pair of gloves to avoid similar incidents he was denied since that wouldn't have protected him.
In the thirteenth trip, SCP-507 again found himself in the reality shrouded in complete darkness, while hearing subtle breathing. Navigating through the environment, 507 came across a source of light at the end of a corridor and soon ran towards it. However, as he ran into the source, the light grew in intensity which began burning his skin. 507 fell unconscious from the pain, but his eyes were protected by someone, possibly the Smiling Man, putting protective sunglasses on him. 507 then awoke after shifting back to his reality and attempted to return to the Foundation though his injuries caused him great discomfort while moving.
In the fourteenth trip, SCP-507 traveled to a world identical to his own. Wanting to learn if this world had any differences from his he went to a public library to access the computers. From the local internet, 507 learned that in this reality, President Lincoln was assassinated by his vice-president to usurp his place, leading to the presidential election being replaced with a "tribe-leader-like" function in which candidates would become the new president of they killed the current one, and to 507's surprise the local presidents had been the same as his world's. He then returned without any problem and reported his findings to the Foundation. This world was probably the home reality of SCP-507-B.
In the fifteenth trip, SCP-507 was transported inside a cave with extreme heat. Getting out of the cave, 507 saw that all of the surrounding area was a vast wasteland before noticing what appeared to be two suns in the sky. As he tried to discern if the suns were either extremely large or too close to the planet, the "suns" were revealed to have been a pair of eyes belonging to a being watching as it blinked and turned its gaze away, causing the temperature to lower. 507 terrified from this revelation, went back to the cave to wait to go back.
In the sixteenth trip, SCP-507 was presented with a gigantic mountain made of what appeared to be pudding. He excitedly began eating it until he went back. As in a trance, 507 went to the cafeteria asking for more of the pudding before fainting. After waking up, he still requested for the pudding, though he did explain where he had been. He was then informed that what he was eating wasn't pudding but something else. 507 would then experience hallucinations of the "pudding" which ceased the next day.
In the seventeenth trip, SCP-507 teleported inside the facility of a British organization analogous to the Foundation known as the Society for Containment of the Paranormal. As the facility was mostly the same as one he resided, 507 failed to realize he had shifted, but his presence was soon noticed by the Society staff which subdued him and took away all of his equipment. The staff demanded to know who he was and how he broke inside, though 507 didn't give complete answers as he still believed he was with the Foundation. He tried to explain his property to the Society but this claim was dismissed and he turned into a D-Class. Thankfully, he returned to his reality where was found by the Foundation in the Service Tunnel 6r3bk and was given replacement of his previous equipment.
In the eighteenth trip, SCP-507 was located to a vast field under a pouring rainfall. He tried to find a place to shelter himself, but noticed humanoid entities staring at him from the distance. 507 attempted to get away from them, only to be surrounded by the entities which began getting closer to him. Luckily, he went back to his reality in the cafeteria, and was treated of his hypothermia along with being granted a set of warm clothes. In the nineteenth trip, SCP-507 fell into an enormous body of water inside a deep cave. Trying his best to swim, 507 was able to finally reach land after some time and upon getting on land he observed his surroundings, discovering a hole to the surface in the ceiling from which he appeared to have fallen. He then came across a series of man-made tunnels that also had holes to the surface, and as he explored the environment he realized that because he was now underground he would be transported into solid ground and die when he returned. Fearing for his life, 507 rapidly attempted to climb up to the surface, and upon succeeding he found other enormous sinkholes that led underground. After returning he requested to be taught diving lessons, only to be denied.
In the twentieth trip, SCP-507 went to an identical reality with the difference being this universe's version of the Foundation and contained several more anomalies and was apparently more liberal. This Foundation allowed 507 to join them and he quickly rose through the ranks. He ended up serving the Foundation for three months, and while assisting a team in acquiring a new anomaly he returned to his reality. With the information he had gathered, the Foundation was able to contain the anomalies its counterpart had already acquired, but when 507 asked to join the organization he was denied.
In the twenty-first trip, SCP-507 was captured by some gigantic alien creatures that imprisoned him in a transparent container which was then placed in a shiny surface. Tomorrow, tubes were inserted into his mouth to force feed him pudding-like food which began fattening him even more before one of the aliens arrived to extract him. Thankfully, he shifted back shortly after the tubes were removed but because of his obese state he was about to die. The Foundation found him and quickly returned to him to the site where SCP-394 was used to remove the fat he had gained. After recovering, he refused to eat any more pudding and began working out.
In the twenty-second trip, SCP-507 arrived to a world with the buildings coated in metal sheets and the sun was too bright. Soon after arriving he was apprehended by local law enforcement and sent to a manufacturing facility where he was hung upside down on an assembly line. He was told that the sun's rays had become radioactive and the inhabitants were required to wear reflective titanium armors for protection, hence why metal sheets shaped after his body were being put on him. During the process he returned to his reality, still hanging upside down from a tree. After the staff brought him down, 507 was given at his request some sunscreen and an eye exam.
In the twenty-third trip, SCP-507 found himself surrounded by dried corpses inside a metallic container with a single flickering light and hanging from a single chain. As he looked out of one of the windows he saw other similar containers hanging from a moving web of chains while the outside space was shrouded in complete darkness. As time went the corpses in his container began moving every time the light flickered, though they appeared to be friendly to 507 as when he was doing something they either mimicked him or assisted him in his actions. Because of this, he found it difficult to sleep and pass the time until he returned. After shifting back, he was found by the Foundation inside a padlocked metal shed, behind an abandoned desolate house
In the twenty-fourth trip, SCP-507 went to an environment resembling a crowded casino filled with countless slot machines. Checking these machines he found that they didn't require money and we're free to use. However, when he pulled the lever the machine dispensed a letter in which cryptic sentences were written based on the combination rolled. 507 decided to make a list of sentences, which ranged from supporting to disturbing, from every combination to present to the Foundation when he came back.
In the twenty-fifth trip, SCP-507 arrived to a long white corridor lined on both sides with metallic doors, each having a keypad, speaker system and clipboard written in an unknown language. Approaching one of the doors for inspection, the entity imprisoned behind the door spoke to 507 through the speaker, begging him to let it out as it was innocent. 507 at first agreed to free it as long as it didn't stab him, confusing the being as it didn't know the meaning of stab. 507 explained to the entity what stabbing is, and the entity promised not to do it as the objects it possessed were blunt, causing 507 to not open the door or any other out of fear of being attacked.
In the twenty-sixth trip, SCP-507 travelled to an environment with heavy snowstorm and immediately tried to find some shelter to no avail. He would have surely died from the frost had not been a man wearing protective furs who pulled 507 into a nearby cave. The man helped 507 remove his wet clothes and enter an underground hot spring to warm himself before removing his furs and entering the spring as well. The was revealed to be an alternate version of 507 bearing tribal scarring on his limbs, shocking 507. The two talked for some before he shifted back to his reality in a city where he was captured by the local police due to being naked on the streets. The Foundation soon came to get him back and once back to the site he told the personnel of symbols on his counterpart and wished to know their significance, though the Foundation was unable to find any meaning or connection to any group.
In the twenty-seventh trip, SCP-507 arrived yet again in the pitch black darkness, with the sound of crying nearby. Upon activating his flashlight, he discovered the "Smiling Man" leaning towards him. Brown liquid leaked from around its sunglasses. The Smiling Man pushed its face closer to subject's and uttered the phrase, "Why did you do this?" The Smiling Man then wiped off a portion of the brown liquid from its eyes with its hand and began caressing 507's cheek with it. 507 forcefully pushed the Smiling Man away. He observed that the Smiling Man's business suit contained several holes, with brown liquid trailing down from them. He drew his firearm and pulled the trigger; however, for unknown reasons, the pistol did not fire. The Smiling Man began slowly walking towards 507. He ran for approximately 10 minutes and spent the rest of the shift huddled in a corner. After returning home, a human heart with the words "I NEED YOU" written with the mysterious brown liquid was discovered in his hand. 507 claimed that the object was not in his possession during the shift and did not know how it came into his possession. He later asked for a more reliable pistol, but it was rejected since they didn't know what caused the gun to misfire in the first place.
In the twenty-eighth trip, while he was reading in his quarters SCP-507 once again returned to the forest, but this time the plants didn't scream. Wanting to learn about the environment, 507 went the highest hill he could find to observe the surrounding area. After arriving at the top he discovered that the entire environment was concealed within a gigantic blue dome, suggesting he was in what appeared to be some kind of preserve, and judging by the shape of the dome he was far from the center. Shifting back to his reality he had been transported 7km, or 4.3 miles, North-East of the site. In the twenty-ninth trip, while sleeping SCP-507 was transported to an alternate version of the Artic along with his bed sheets and pajamas. Remembering a TV show of how to survive in a cold environment, he attempted to build a crude snow cave with his hands until he was attacked by a polar bear. As the bear was about to kill him, 507 returned to his room where he lied unconscious and bleeding profusely. The Foundation quickly intervened and sent him to the infirmary to patch up his wounds. Because of this incident, 507 was given a sheathed knife attached to a belt which he would always keep in order to have a proper weapon to defend himself.
In the thirtieth trip, SCP-507 teleported to a version of the Foundation facility he lived where he was quickly apprehended by the local personnel. He was soon interviewed by the staff about his canine teeth, revealing that the humans of this universe were carnivores. After answering their questions, the personnel fed him numerous meat-based meals, then healed his scars from his last trip and allowed him to sleep in one of their chambers. The next day, the staff took some piece of his flesh from his thigh in exchange for more meat food which significantly fattened him. However, after a month and a half of eating, the staff took him to their kitchen where it was revealed that they were actually cannibals and prepared to cook him, starting with cleaving his left hand before he shifted back. He reappeared in the kitchen of his reality's Foundation where he attempted to cover his stump with expletives. He was rushed to the infirmary where he received a replacement for his hand.
In the thirty-first trip, SCP-507 arrived to a large, opaque dome filled with plant life but no sign of humanity. Exploring this new environment he saw the planet Earth through a nearby window surrounded by complete darkness. He was then approached by a tall humanoid who asked him on his small size. 507 asked the humanoid where he was located to which it replied that they were in Base 12, oxygen and vegetable wing, but when asked it why Earth was in the sky the humanoid said that the planet was the moon. After the humanoid departed, Earth set at which point the ground outside of the dome illuminated as if the sun had risen, revealing the planet 507 was located to be the moon. He sought to further explore the environment but was shifted back to his reality. Upon returning he asked for a camera to take pictures of the environments he visited but was denied. In the thirtieth-second, while he was attempting to sleep SCP-507 was transported to a large body of water in which he sank thirty-five meters deep. When he resurfaced, 507 noticed dark shadows moving beneath him in the water and bright lights in the distance, but refused to approach either of them. However, he began experiencing breathing problems due to inhaling methane, and after returning he was granted a breathing gas tank.
In the thirty-third trip, SCP-507 found himself in a paradise-like environment which left him so astonished that he couldn't move. As he became thirsty and hungry nearby plants shoot out a nutritious sweet liquid into his mouth that satiated him. The next day, 507 was approached by a local beautiful woman roughly the same age as him, and despite speaking different languages they could perfectly understand each other. As they conversed, 507 became infatuated with her, and the two fell in love. Sadly, as they were about to kiss, 507 shifted back to his reality, devastating him as his ideal world was now gone. He broke down in his room, lamenting why he was forced to leave, and as he became depressed he attempted to commit suicide, hadn't been for the staff's intervention. In order to keep him happy the Foundation gave him various delicious foods and beverages along with pictures of attractive women but all failed to match the beauty he had witnessed, and wished to find a way to remain forever in the world he traveled, only to be even more disappointed when staff reminded him he was unable to do so. The reality he visited appeared to be the same as SCP-6001's.
In the thirty-fourth trip, SCP-507 teleported to a world filled with colorful crystals of various sizes with a smaller and sun in a blue hue. Exploring the surroundings, he noticed that the crystals were actually living creatures that moved, along with smaller crystalline creatures resembling crustaceans. Getting thirsty, he searched for water, but when he finally found it he was unable to drink due to tasting like sand. He was then attacked by one of the small creatures, injecting a silicon venom in his finger. In that moment, he shifted back and with staff's help he was able to fully recover and asked for normal water. In the thirty-fifth trip, SCP-507 ended up in a world completely covered in seawater. Wearing his scuba gear, 507 swam down 50 meters deep for three minutes until reaching the seafloor. On the floor 507 found countless submerged abandoned buildings and rubble covered by aqueous plant life while numerous skeletons were scattered. As he explored the underwater city, three black fish-like creatures began approaching him, prompting 507 to arm himself, but before the confrontation could occur he returned to his reality, finding himself in a Foundation restricted area. He was swiftly removed from the area and was given a pair of waterproof binoculars.
In the thirty-sixth trip, SCP-507 was located to a bedroom where he was welcomed by a group of friendly people. They proceeded to guide him throughout the house, but 507 noticed an unusually high number of windows and upon looking outside he saw that the building was encased inside a dome surrounded by countless cameras. Questioning the people about this, they explained to 507 that they were in zoo-like enclosure for non-humans to observe them. In the thirty-seventh trip, SCP-507 appeared in an endless forest of apple trees inhabited by a humanoids race resembling Dr. King. Upon meeting him, these people gave him a message to deliver to King, asking him to return home to them. 507 shifted back to his reality, appearing in King's office, but was prevented by staff from meeting the doctor out of his own safety.
In the thirty-eighth trip, SCP-507 arrived to an alternate universe which at first appeared to be identical to his own, but upon further exploration he discovered that the Foundation staff and the contained humanoid anomalies had switched places, with the anomalous humans containing the troublesome personnel, while the research and Class-D personnel remained the same. Despite the lack of hostility, the surroundings were filled with biological, memetic, and other hazards which should have led to a K-class scenario. After returning, 507's only request was for the local research staff to have heightened psychological evaluations, though it is unknown if it was granted or denied. In the thirty-ninth trip, SCP-507 traveled to an endless, but otherwise normal forest that completely lacked any other lifeform like animals or insects. He stayed in the forest for around three weeks, during which he attempted to reach the end of the forest to no avail, and as he had run out of supplies he was forced to eat local nuts and fruits. Upon returning back, he was granted enough non-perishable rations to last a week.
In the fortieth trip, SCP-507 was sent to a world comprised solely of candy, appearing like Willy Wonka's factory "on steroids". During his stay, 507 ate an abundance of candy, gaining considerable weight before leaving the that reality. In the forty-first trip, SCP-507 found himself in alternate version of America which had been first colonized by the Japanese before the British, allowing Japan to take over most of Asia and turn it into one of the two biggest world powers. 507 spent several days in that world without any problem before shifting back.
In the forty-second trip, SCP-507 teleported to a pitch-black world illuminated by hanging fruits emitting light, but in this world he found that his flashlight was less effective than usual. During his exploration, he encountered a humanoid entity also emitting light which did nothing but follow 507 for some time. Eventually, the entity left and soon 507 began hearing breathing near him. Switching his flashlight on, he found a black monster hidden in the darkness which immediately attacked him. 507 received several cuts on his left arm, but thankfully he shifted back to his world and was patched up by staff, along with being granted a stronger flashlight. In the forty-third trip, SCP-507 appeared in a shifting white landscape overlooking a city with impossible structures comprised of purely of light. Soon two celestial beings emerged from the city to talk to 507, but their mere appearance caused him to go blind and their words ruptured his eardrums. He then felt like being undone by the entities, at which point he lost complete consciousness. When he shifted back, he was found bleeding from his eyes, nose, ears and mouth, but despite this he didn't sustain any major injuries. Because of this incident, 507 went in a coma in which he remained for 42 days before waking up.
In the forty-fourth trip, SCP-507 went to an alternate world where an intelligent reptilian race was the dominant species while humanity was just another race of animals. As soon as he appeared, the reptilians captured and stripped him naked before letting him go in a human reservation, intending to hunt him alongside other humans later on for sport. 507 was able to survive for longer than his fellow humans since he was more intelligent than them, wearing animal skins and equipped with a crude crossbow. He spent most of his time in this universe hiding in trees before returning to his reality in a national park and replacing his lost equipment. In the forty-fifth trip, SCP-507 arrived to an alternate world in which buildings were made out of humans, and each individual took turns performing jobs which included being transformed into buildings or food. In the following week, 507 didn't require to do any job but all of his clothes were stolen by some thieves and left completely naked though he retained his equipment. After returning, he wished to avoid people for some time.
In the forty-sixth trip, SCP-507 found himself in a dimension appearing as a vast endless field solely comprised of various gelatins with a glinting metallic object in the distance. 507 decided to make his way to the object, but because it was so far away he spent several days walking and sleeping in puddles of liquid gelatins. Ultimately he was unable to reach the object as he shifted back and having had enough of gelatins he avoided eating soft foods for a month. In the forty-seventh trip, SCP-507 was located in a large basketball court in which two humans and four aliens were playing. He was informed by the locals that he was in the "All-Species Sports Center" and checking the other games that were being played by other non-humans, he was apprehended for trespassing. He was put in a locked room where he stayed for seven hours before shifting back to his reality fifteen feet above the cafeteria's ground.
In the forty-eighth trip, SCP-507 arrived to an alternate reality which had frozen in time, while the sky was red and pink and displayed the message "ERROR 14528: LOADING TIME: expec. 228-342 years". Checking the local computers, he discovered that this reality had been stuck in time since December 24, 2012, and appeared that the world was buffering. He stayed in this world for two months, eating local food before shifting back. In the forty-ninth trip, SCP-507 teleported to an alternate universe where the human lifespan was just 24 hours, people living their entire lives within a day. As he stayed in this reality, 507 became internationally famous as an immortal wise elder who advised people, and after two months he returned to his universe in Idaho.
In the fiftieth trip, SCP-507 manifested two meters above the stands in a large arena where four militaristic teams were fighting each other. Three minutes in this world, security captured him and imprisoned him in a cell, informing 507 that as punishment for trespassing he would be forced to participate in the next game, though he was allowed to watch the current matches in an old tv. Watching the games, he learned that the games were controlled by "The Master, Zero-Two-Four" who occasionally interrupted the matches to modify the rules, and eventually saw some Foundation researchers being forced to play. After thirty-six hours passed, 507 went back to his reality, appearing in a janitorial closet in the site basement. 507 requested to use the site gym to prepare himself in case he returned to that world but was denied since it wouldn't help him much.
In the fifty-first trip, SCP-507 was transported to a television or movie set where actors were playing the characters from the SCP Foundation reality. Upon meeting some of the actors, 507 was mistaken for the actor playing him and as a result he was forced to prepare filming his scene. While staff was applying stage makeup that looked like deep gashes running down his upper body, he shifted back to his world in the break room. In the fifty-second trip, SCP-507 appeared in a heptagonal tunnel illuminated by blue fluorescent lamps and completely covered and inhabited by various species of plants, some of which shouldn't be able to live in these circumstances. 507 decided to reach the end of the tunnel, eating fruits produced by the plants and noticing the phrase "043 WARNING" spray painted on the walls every one hundred meters, but after six days of walking he was unable to reach the end and shifted back to his reality.
In the fifty-third trip, SCP-507 awoke in a dark room inside a tall building where the time was 07:33:84 and the date 3120 GAN 01. Ascending the building, 507 reached a air traffic control center from which he saw a destroyed airfield inhabited only by statues that moved when not looked at. Fearing for his life, 507 refused to go outside and opted to spend the ensuing four days in this universe hiding behind the stairwell he had walked on and looking at magazines and flight manuals written in a unknown language, all the while hearing explosions in the distance. In the fifty-fourth trip, SCP-507 was sent to an alternate version almost identical to his with the main difference being that all humans were fused to furry costumes. Upon seeing him, the local Foundation personnel attempted to apprehend him in order to make him a furry, but he managed to escape. Unfortunately, due to breaking his leg in his last trip, 507 was caught by another staff member who forced him to wear a large blue dog costume which partially fused to his skin. 507 soon returned to his reality, and had the costume surgically removed but had to undergo skin grafting, prompting him to receive a thin skin suit.
In the fifty-fifth trip, SCP-507 went to an alternate reality which lacked any other color except for different shades of the color red. The local Foundation quickly contained him as he was considered an anomaly due to being colored differently. The next day he returned to his home reality and having become sick of seeing the color red, he replaced his red blanket with a green one. In the fifty-sixth trip, SCP-507 found himself in a featureless white room in the sole company of the 41st American President George H. W. Bush who produced numerous broccolis which he threw at 507, while repeatedly saying "1992". In the fifty-seventh trip, SCP-507 arrived to a black room with no apparent door. He proceeded to knock on the walls to find a way out, but then noticed a D-Class with the head of a cat in the corner holding a baseball bat. This individual hit 507 in the stomach with the bat, telling him to not leave this time before leaving the room by phasing through one of the walls. 507 attempted to break out of the room, but thankfully he returned to his reality and his bruised abdomen was treated.
In the fifty-eighth trip, SCP-507 awoke in a field near a farmhouse and a barn which appeared completely normal. He approached the farmhouse to see if there was life in this reality, and was greeted by a man and his family who only spoke Spanish. Using a Spanish-to-English dictionary, they were able to communicate with each other, with 507 telling them he was suffering from amnesia and learned he was in a country that had rebelled the Spanish Empire. The man was generous enough to drive 507 to a nearby town and give him some money. 507 then went to the town's public library to use a computer that offered the English language and learn more about this world. After that he found a partially broken three-wheeled bicycle with a backrest seat in a trash can, but while riding it he shifted back several kilometers away from the site.
In the fifty-ninth trip, SCP-507 manifested in a large hospital's maternity ward where he was discovered by a nurse with a unrecognizable obscured face. The "nurse" apprehended him due to disturbing the other patients because of his "strange" appearance, and strapped him to surgical table to send him to the operation room. As the restraints were removed to prepare for the operation, 507 took the opportunity to jump off the table and escape. The locals attempted to recapture him, forcing him to fight them with a chair and screaming at them, but thankfully he shifted back to his reality in the site's medical wing. Upon returning, he requested to be amnesticized as the experience proved to be traumatizing for him, but was denied. In the sixtieth trip, SCP-507 went to unknown dimension in which he was apparently captured, stripped of his equipment and sedated leading to something bad happening to him, leaving burn marks across his face and chest. After he shifted back in only a blue bathrobe, he was unable to remember anything and when he tried to remember he would fall unconscious and bleed from his eyes, nose, ears and mouth.
In the sixty-first trip, SCP-507 found himself in a alternate version of his chamber containing the skeleton of this reality's SCP-507. Grabbing his counterpart's loaded gun 507 used it to shatter the observation window in order to get out, but water began pouring in, filling the room and knocking him out. He then awoke wearing a diving suit inside a dark room with waist-deep water and various crates scattered around. He attempted to unsuccessfully leave the room, and a few hours later a trio of fish people entered through a trapdoor and gave him wet seaweed and meats to eat before telling him to not smile as it hid lies and to not leave. As days went on he removed his suit, and one day one of creatures returned to take some rusty medieval weapons before leaving. Becoming curious of what the creates contained he opened them, finding microwaved popcorn, laundry, toy kaleidoscopes, machine parts, a November 1996 Boy's Life magazine and the body of the smiling man, terrifying 507 who avoided that crate for the reminder of his time in this reality. He shifted in the site's freezer next to the cafeteria from which he was soon released and given a warm blanket.
In the sixty-second trip, SCP-507 began endlessly falling through what appeared to be a infinite sky. He spent the remainder of his stay in this reality like this while observing large birds in the distance before shifting back to his reality buried in a grave in India where he was found by the Foundation. In the sixty-third trip, SCP-507 was transported in a cramped crawlspace between two walls where he spent an entire day. As he was unable to move he screamed for help, but was only responded by a dripping noise and a scurrying creature, and when he finally returned to his reality he began hyperventilating before collapsing.
In the sixty-fourth trip, SCP-507 arrived to an alternate version of Earth where he was met with 50,000 versions of himself which had organized in a political rally named the "People's Dimension-Hopper Republic". In the following two weeks, 507 assisted his counterparts in overthrowing the United States government and establish their own republic solely comprised of themselves. 507 was elected to the office of representative of Massachusetts, but as he was about to introduce his first piece of legislation he returned to his reality.
In the sixty-fifth trip, SCP-507 appeared in a train traversing through a dark void. The occupants didn't seem surprised at his sudden appearance out of nowhere and after half an hour a faceless humanoid asked him for his ticket. 507 told it he didn't have one, causing the humanoid to search his body, confiscating his weapons, telling him he would be forced to leave the next stop and that he would be fined 10 minutes. In his free time, 507 attempted to reach the end of the train to no avail, and after walking three kilometers he shifted back to his chamber and his gear was replaced.
In the sixty-sixth trip, SCP-507 teleported to an alternate version of his chamber in the Shark Punching Center's universe, and upon arriving the intercoms warned that SPC-507 had displaced and if it were to be found it should be punched. Believing that it was referring to him, 507 began fearing for his but a SPC doctor soon entered the chamber and informed him that he wasn't their target. 507 remained in his chamber for three hours, at which point a shark version of himself materialized near him and began attacking him. Luckily, two SPC guards entered immediately and punched the shark in its face, while 507 shifted back to his reality. After he was healed of his wounds, 507 requested to be equipped with shark repellent but was denied due to the site not having any normal shark repellent.
In the sixty-seventh trip, SCP-507 was sleeping when he was located to alternate reality, and slept through the entire time, still sleeping after returning without seeing anything of that reality. Because of this, 507 was equipped with a wristwatch that would sound an alarm everytime he shifted. In the sixty-eighth trip, while SCP-507 was talking to Agent M█████ he blinked, at which point he was transported to another reality before returning for less than 100 milliseconds, opening his eyes and not noticing anything. The agent he had been speaking to noticed the sudden shift and informed 507 and the other personnel of what had happened.
In the sixty-ninth trip, SCP-507 arrived to an empty highway and proceeded to go to the nearest population area. Upon arriving to a city he saw the few pedestrians that were outside were transfixed to retro television sets, and becoming curious sat in front of one of them to see what they were showing. He saw an ad for the "Reality-Cleaning Laundry Detergent" using Christian imagery which hypnotized 507 as he refused to turn his gaze away from the tv for 53 minutes. After shifting back to his reality in the employee break room, 507 began talking nonstop about the detergent, wishing to have the product, until he fully recovered from the hypnosis. In light of this incident, it was suggested to have 507 undergo cognitohazard training but it was yet to be approved by the Council.
In the seventieth trip, SCP-507 went to a facility analogous to the Foundation site he was contained with the main difference being that the living anomalies were allowed to freely move around and apparently there was nothing outside of the structure. While traversing the building he saw that the anomalous beings were wearing traditional garments and along with the security were all friendly to him. Finding no way out, 507 spent a couple of days in the cafeteria before a sound was heard from a nearby speaker announcing the time of "ploking". As everyone gathered to perform this seemingly religious practice, one of the guards slipped and fell to the ground, causing everyone else to turn their gaze and ignore them, but 507 asked what ploking meant. This caused one of entities to turn hostile and perform a kinetoglyph that rendered 507 deaf, blind and with anosmia. 507 attempted to counteract but fell to a ground colder than the floor of the building, and spent the next ten days in this state pacing, sleeping, crying, and eating his rations, all the while an avian entity arriving from the distance, landing on his head before sighing and leaving. He then shifted back in a unoccupied chamber in a restricted area of the site where he was found unconscious and after waking back up the disabilities set on him soon wared off. Traumatized from this event, he was again appointed a therapist.
In the seventy-first trip, SCP-507 manifested in a tunnel system filled with murines, ophidians, and arachnids covered in cardboards. He got hold of a murine, but after ten minutes children wearing cardboard costumes, almost perfectly resembling SCP-3663, appeared either proclaiming to be the tunnel monsters or wishing to cease this game and remove the costumes. 507 soon shifted back and explained what he had seen, prompting the Foundation to search for more instances of SCP-3663, while he was granted a pet cage for his new pet murine.
In the seventy-second trip, while SCP-507 was sleeping he teleported to a hot underground tunnel mostly covered by a soft black mold. Walking 50 meters down the tunnel and then turning right he came across a lake inside a cavern with a tall olive tree and an alternate version of SCP-3048 at the center, but upon a closer look he noticed that the water would freeze when exposed to his body heat and saw that SCP-3048 was frozen in the lake. Fifteen minutes went by, at which point SCP-3048 awoke and after noticing 507 he frantically tried to talk to him in a unknown language while gesturing at the tree and the water. 507 thought of rescuing him, but not wanting to also be trapped in the lake he decided to leave and further explore the tunnel, only to return to the cavern after walking 300 meters. 3048 again attempted to talk to 507 before a tall cervine entity descended from the tree's branches to urinate on his head and immediately retreating after finishing. 507 then spend the next eight hours eating his rations, pacing, sleeping and ignoring the screaming 3048. Returning to his reality, he brought with him some mold for the Foundation to study and requested books to pass time which were provided.
In the seventy-third trip, SCP-507 fell into mud at the bottom of a massive crater, spraining his ankle. After crawling out of the crater, which took him some hours, he noticed that everything, including humans, animals and the sun, had frozen in place which didn't move for the next four days. Exploring the nearby town, he discovered that time had frozen on February 7th of 2034, and eventually came across a building belonging to Vanguard staffed by Foundation personnel.
In the seventy-fourth trip, SCP-507 manifested in an alternate reality where the planet Earth was experiencing constant earthquake which was normal, and as a result humanity had adapted to it and constructed buildings that could withstand the never-ending shaking. Upon arriving people got confused over 507 not being able to walk normally and was eventually apprehended by police under the suspicion he was intoxicated, but was let go after he proved to be sober. As he was unable to find the native version of the Foundation, along with having little money, 507 began living in a homeless encampment in a central park. After 47 days passed, during which he got used to the constant earthquake, 507 suddenly awoke from sleeping when the ground suddenly stopped shaking and stayed in place, causing chaos to erupt and the buildings to crumble which costed the lives of countless people. In the ensuing nine days, 507 began working for a volunteer disaster response effort to help save survivors stuck beneath the rubble, but shifted back to his reality. Upon returning, he found it difficult for a bit to readjust to his world since he had been accustomed to the earthquake before the Foundation found him. 
In the seventy-fifth trip, SCP-507 appeared in a version of Earth with a reversed day and night cycle which took him to some time to adjust. Wandering through this world, he came across a village solely inhabited by children who were afraid of him. As he explored the village he found at its center a playground in which there was only one child that didn't scream at him. Curious, 507 began approaching the child, but they like everyone else attempted to avoid him. 507 decided to follow them until arriving at the edge of the village where the child entered through a doorway in house before the handleless door closed behind them on its own. 507 then attempted to hear what was going on inside the house by pressing his ear on the door, but found it extremely cold, and with nothing else left to do he shifted back. In the seventy-sixth trip, SCP-507 got transported to a version of Earth where his point of view switched to a third person perspective, looking at his own body which he could still control as normal. Although this world was mostly normal, he found all food was completely tasteless and everytime he ate his hunger didn't extinguish. After several failed attempts at satiating himself he decided to stop eating altogether until he returned to his world when the week was over. Upon returning he was granted a full-course meal to recover from his malnutrition.
In the seventy-seventh trip, SCP-507 went to an alternate world which was for the most part normal for the main exception being that Christmas was celebrated all year long. Having arrived in September 507 remained until December, at which point all Christmas decorations were taken down and the environment became normal. During this time, 507 was chased by agents belonging to the local version of the Foundation who then had an armored van try to kidnap him, but he immediately shifted back when he was about to be captured. After returning, he requested that the site be stripped of all Christmas decorations as he became sick of the festivity, but was dismissed.
In the seventy-eighth trip, SCP-507 slipped on a SCP's residue causing Sr. Researcher A. Yik to try prevent him from falling by catching him, but in that exact moment the two traveled to underground ruins of unknown origin. In this new reality, 507 explained their situation to Yik grabbed him to be in continual touch so she wouldn't be left behind. They then went to explore their surroundings, taking notes of the structure they were in. Yik became excited at learning about the artifacts they uncovered, finding a possible link to an anomaly in their world, though 507 became increasingly bored. After thirteen hours passed, they shifted back to their world, relieving 507 but leaving Yik in disappointment. 507 then requested a mobile gaming device, a box of Lego bricks and a Rubik's Cube to pass time when in uneventful situations, but only the latter one was approved.
In the seventy-ninth trip, SCP-507 found himself in a alley in an alternate world that was in black and white and the only sounds that could be made was speaking. Getting out of the alley he found that all humans were mimes that communicated in sign language and appeared like riding invisible vehicles. He attempted to speak to them, but everyone reacted horribly to him speaking, closing their ears, while the drivers' vehicles demanifested. 507 was soon apprehended by what appeared to be the local police wearing noise-cancelling headphones who handcuffed him and ductaped his mouth before taking him to a nearby building. There a individual attempted to interrogate 507 in sign language, but as he was unable to understand anything, the interrogator was forced to write what he was speaking to him, informing 507 that he was a anomalous being that would be put inside a facility that could house those like him. Awaiting for his transfer, 507 attempted to learn the mimes' sign language but before he was taken to the local version of the Foundation he shifted back to his reality, reappearing in Site-19's women bathroom. There he was immediately knocked out by Guest Researcher K who believed him to be a pervert, but after things were cleared out he requested to be taught sign language which was approved.
In the eightieth trip, SCP-507 located to the city of Kampala, Central Africa in an alternate world in which the apes were the dominant species while the humans were considered animals. However, recently humanity began gaining intelligence and started an uprise against the apes, claiming several cities and causing a devastating war. After evading a battlefield, 507 was captured by the intelligent apes, stripped of his gear and caged in a concentration camp alongside other humans, where they were punished if they attempted to communicate with each other. Soon his captors discovered that 507 was far more intelligent than his fellow humans, and seeing a valuable asset in the war they taught him their language and offered him to join their army in the war. 507 was about to turn the offer down because he was unfit for battle, but before he could give an answer he shifted back to his reality. Back to the Foundation, he was retaught grammar, and asked for psychiatric treatment for his PTSD but his request was denied as he wasn't actually traumatized. It was later reported that the document in which SCP-507's shifts were recorded, had been changed by an anomaly, meaning that a number of the afromentioned trips could be false and had never actually happened.
During one of his shifts, SCP-507 witnessed a version of the Foundation cross-testing SCP-009 with SCP-107. This resulted in red snow falling in the surrounding area, and soon was absorbed by the local plants which instead of dying merged together with the substance to create a platform. 507 then reported the horrifying results to his version of the Foundation, causing the organization to be wary of the substance.
In their attempts at neutralizing SCP-682, SCP-507 was strapped to an incapacitated 682's left forelimb with nylon zip ties, and after 7 hours and 52 minutes 507 teleported to an alternate reality along with the monster. Upon arriving to the alternate world, he and 682 were found by the local version of the Foundation and seeing its counterpart from 507's reality brought another 682 to their universe, decided to tie him to its version of 682 in order to get rid of it and take revenge on its counterpart for bringing in a second monster. After writing a note and pinning it on 507's chest, he shifted back to his reality, bringing with him the alternate 682, causing the Foundation to resume its attempts at killing the immortal lizard.
SCP-507 once traveled to the interdimensional kingdom of Alagadda governed by the Hanged King. There he encountered another interdimensional traveler Ickis of the Wandsmen. The Wandsman could smell the fear emanating from him and was shocked to see him here, but as he appeared 507 soon disappeared without any trace, leaving Ickis dumfounded. Ickis would later recount this encounter to Dr. Calixto Narváez when the latter entered Alagadda for the second time.
One day, SCP-507 arrived to the underground city of UnLondon where he immediately took shelter in a nearby abandoned home due to the poring rain. There he found a crowbar he could use as a weapon and a book along with some maps hidden behind a wall which read about a man trying to form a rebellion against UnLondon's government and escape to the surface. However, a bird-like surveillance drone spotted him and the book, notifying a nearby Bobby. The Bobby attempted to arrest 507, but the latter managed to escape by throwing some of the "Wonderfood" to the ground, making the Bobby slip, and throwing a mattress out of the window to cushion his fall after jumping out. Waiting to be teleported back to his home dimension, 507 wandered through the alleyways to keep a low profile and avoid the surveillance drones or the Bobbies. Having run out of food, he was forced to consume the disgusting Wonderfood that intoxicated the inhabitants. While sleeping, he was awoken by one of the Wretches, an old man who turned out to be the book's author. The man, proclaiming himself as the Leader, brought 507 to his secret hideout believing he would help him and his fellow people leave the UnLondon to the surface. Unfortunately, a smaller drone which 507 had unknowingly digested with the Wonderfood emerged through his throat, causing him to vomit it out, at which point it notified all Bobbies of the duo's location. The Leader attempted to kill 507 for blowing his cover, but before he could deliver the killing blow, 507 went back to his chamber, leaving the Leader at the mercy of the Bobbies. Upon his return, 507 shared his findings with the personnel and was rewarded a proper porridge under a sunny day.
During Halloween, SCP-239 wanting to celebrate altered reality into a Halloween environment. In this alternate reality SCP-507 was turned into a teenager named Guy Hooper. He went to DJ Scravecrow's performance inside a barn to have fun, but the event was interrupted when Iris fought with her possessive boyfriend Abe. Iris stormed out of the barn, but Guy noticed Abe going after her and concerned over her safety he decided to follow them. Abe began shouting at Iris, only to be interrupted by Guy telling him to leave her alone. Abe attempted to intimidate him, but luckily for Guy Alex soon arrived to tell Abe to leave. He refused and as he was at a disadvantage pulled out his pocket knife to attack Alex, hadn't been for Guy grabbing one of his legs which allowed Alex to beat him up. Infuriated Abe left in his truck, and with no other means for Iris to go back home Guy offered to drive her home in his own car. On the road, the vehicle to run out of gas due to a hole in the tank, forcing them to walk back home. They then came across Abe's truck and saw it was ruined. Inspecting the car they found what appeared to be Abe's bodily remains coated in a black sludge, meaning he was killed by a monster. Fearing for the safety of the others, Guy and Iris went back to the barn to warn their friends.
Returning to the barn, the two met Alex drinking with his friends Porkchop, Spencer and Lance, and tried to explain to them that a murderous monster was on loose. However, as they talked the barn suddenly collapsed completely, causing the boys, save for Guy, to go to the debris to look for survivors. Unfortunately, SCP-106, who was left unaffected by the reality change, emerged and slowly killed all four of them, leaving only Guy and Iris alive. At Alex's order, the two made a run to Alex's truck while 106 was finishing his job. They sought to drive back to town to call for help, but crashed into a tree, leaving them halfway on the road. As Guy was left wounded, he told her to go on as he sacrificed himself to distract the monster. Saddened, Iris did as he asked and ran through the forest. Guy attempted to hide in the trees, but as his brain was now damaged his crumbled to the ground and his vision went blurry. Soon SCP-106 found him and as he pushed him into his pocket-dimension, Guy saw 106's face changing into that of the Smiling Man's. Recognizing him as SCP-507, 106 locked Guy inside a mental asylum's padded room where the Smiling Man was about to lobotomize him. This alternate reality was turned back to normal after Dr. Clef stabbed 239 with SCP-668 when she attempted to become friends with him, leaving 507 along with everyone else to dismiss the entire experience as nothing more than a dream.
==Possible Endings==
=== Little SCP-507 Lost===
As 507 began going through different realities, he noticed that each reality had anomalies and Foundation personnel. In one universe he found himself inside a child's room where he found some children playing an RPG game which was about a fictionalized version of the Foundation and their contained anomalies. Before he could engage in a conversation with them, he was transported again inside the house of a man named Robert who was living in a imaginary world of the SCP Foundation. 507 then quickly tried to see if there were any anomalies nearby, but was shot by Robert who thought of himself as Dr. Clef. At that moment 507 again was transported to yet another reality. In this reality the world was in a post-apocalyptic state with multiple anomalies roaming around. Upon arriving, he was immediately captured by a tribe formed from the remnants of the Foundation and was put inside an interrogation room where the leader Dmitri Strelnikov demanded to know from what other tribe he came from. However, 507 refused to give a response and teleported away, leaving Strelnikov concerned. As 507 arrived to yet another reality, he seemingly succumbed to his injuries.
===Rising===
When 507 returned from an alternate dimension with some unknown metal, he found himself inside SCP-343's chamber. 507 blamed 343 for his condition, but the latter tried to reason with him and tell him that they weren't enemies, 507 refused to hear him and teleported away and back into his own chamber, having gain control over his power. Upon returning to his chamber, a researcher came with excuse to interview him, but in reality they were both moles for the Church of the Broken God and this interview was in fact a farce for 507 to give the researcher the metal which he would use to feed SCP-882. However, 343 caught notice of this and faced 507 in his chamber, demanding to know what he had done. 507 attempted to teleport away, but 343 used his powers to teleport the dimension hopper back to him and as he refused to talk 343 killed him.
=== Person of Interest File #2273/01 ===
After the Foundation was forced to become public around 2004, SCP-507 was one of the many safe humanoid anomalies who were released. One time, he published an autobiography about his time under Foundation custody, with SCP-2273 buying a copy to read. Eventually after several years, SCP-507 would die under undisclosed circumstances.
===Day Trip/A Spin Around The Library===
While reading a book, 507 was transported to the dimension of the Wanderer's Library. Upon arriving he fell on a road where a native dinosaur-like entity picked him up by using its mouth to grab 507's shirt since he was about to be ran over by a car, but 507 misinterpreted as an attack and fled. He accidentally trespassed to a wild area where he was attacked by feral creatures, but thankfully was saved by a local park ranger who took 507 out of the area and directed him towards a town near the Library.
Making his way towards the town, 507 encountered various natives, one of which told him that if he needed to get something to eat then he should enter the Library. 507 decided to enter the Library but as soon as he entered he accidentally stepped on a cat-like wanderer's tail, causing one of the Librarians, Rounderpede, to be careful and finish his job at the Library quickly. 507 then met an octopus-like telepathic entity who offered him to use its coupons to share some soup at one of the Library's cafeterias. As they were about to eat the entity inquired 507 on his confusion over the Foundation. 507 told the entity that the Foundation was necessary to protect people from dangerous anomalies, but the entity argued that 507 wasn't dangerous and he shouldn't be kept imprisoned. However, 507 responded that he could be a danger to people and no one really cared about him, leaving the entity to tell him that if he wanted he could ask them to help him in his problems, but before they could keep talking 507 teleported back to the Foundation. After being interviewed on his latest trip, 507 realized that the Foundation, unlike the Wanderer's Library's natives, were uncaring, and so after another interdimensional trip he completely left the organization with possible help from the Librarians.
===Dimensions 2, 3, and Onward===
When the O5 Council made a deal with SCP-001 (Atonement) to save their universe at the cost of destroying others, all of the Foundation sites erupted in chaos as the Council was killed and the anomalies let free. SCP-507 got out of his cell and with his equipment he made his way through the site that held him, finding it in disarray and devoid of human life. He eventually came across another chamber containing SCP-085, and curious about her he entered, finding her on a paper pad. Wearing a body armor, 085 motioned to the nearby pen for 507 to write so they could communicate. 507 explained to her the current state of the site and asked her if she wished to join in leaving Site-17. She agreed and attempted to guide him throughout the site, but in that moment SCP-001 appeared before, startling the two of them. 507 immediately made a run to the door, only to shift in that exact moment to another reality. He found himself on a vast grassy field in a sunny where he noticed that the paper containing 085 disappeared. Fearing he had accidentally dropped it, he frantically began looking for it, only to be met with 085, now transformed into a real human being.
Now a normal human, Cassie could properly interact with 507 and confused over her sudden transformation and their current location, he explained to her how he must've shifted to an alternate reality where she became real. Traversing the grass field together, the two began bonding with one another, 507 blushing due to being in her presence while Cassie wished to know his real name. 507 told her his name was John but he wished to hide since the name was so generic and boring, but she didn't see anything wrong with that . As the sun set, Cassie expressed sadness that she may return to being a drawing once they returned to their reality, causing 507 to promise to her that he would keep with him all the time and would go on adventures together, making her happy. Sadly, as they walked in the night, SCP-001 reappeared before them, telling the duo that their existence endangered other innocent lives and needed to exterminated. It soon began squashing them inside a force barrier, and with no way out Cassie implored 507 to take them to another dimension. Running out of breath, he tried his best to control his power and suddenly they teleported yet again, this time inside a warehouse. There the lights slowly went on one by one, illuminating numerous canvases depicted 085 in a state of fear and pain, all the while a voice began describing her. Soon 507 witnessed her being forcefully outstretched and crushed, causing her immense pain as she was slowly destroyed. Unable to bear this sight he attempted to look away, only for the geometries to change and force him to see as 085 became a lifeless tangled mess. Distraught over this, 507 collapsed to the floor and made no attempts to escape when SCP-001 appeared to him once more. All 507 could matter was a plea to not kill him, but SCP-001 revealed that it wouldn't kill him and instead sent him back to the dark dimension, leaving 507 at the mercy of the Smiling Man.
=== SCP-5775===
Eventually, the Foundation officially employed SCP-507, becoming Junior Researcher Thomas Yaltz. After discovering SCP-5775, an Ortothan spaceship previously used by the Soviets and was now disguised as Mars' moon Deimos, SCP-507 volunteered to take part of the planned expedition to explore the spaceship. His request was approved and he, alongside Head Researcher Dr. Naomi Lyons, Dr. Regina Beale, Agent Jonathan Bell and Agent Helen Troy, who acted as 507's handler, arrived to the spaceship through SCP-5775-1, and upon entering it found out that most of the crew had been killed by some creature. During the exploration they came across a few survivors, Aleksandr Voyich, Vladamir Smirnov and Anatoly Kuznetsov, but when further exploring the spaceship they discovered the real Voyich's corpse leading to the impostor revealing itself to be the shapeshifting monster responsible for the slaughter of the crew and proceeded to kill both Agent Bell and Kuznetsov before attacking Lyons. As the remaining personnel refused to let the creature alive SCP-507 decided to remain behind in order to blow up the hangar while the rest escaped, since he would simply be teleported to another dimension. As both Beale and Smirnov escaped through SCP-5775-1, Troy also decided to remain behind since she was his handler and before teleporting to another dimension exploded the hangar, possibly killing the shapeshifting creature. Nine days later 507 and Troy returned back to their home reality in Waco, Texas with no injuries and were subsequently picked up by the Foundation.
===SCP-6277===
As SCP-6277, a phenomenon which causes people to see in their reflections their dead loved ones supporting them during critical moments in their lives, began spreading due to some threat coming to the universe, O5-9 who made a deal with one of the entities originating from the universe seen in SCP-6277, got hold of 507 due to him being secretly possessed by an interdimensional entity. After O5-9 spoke the threat's name to 507, it caused the entity residing within him to awaken. It proceeded to explain to the Overseer how it witnessed countless realities being destroyed by the threat and had tried to warn the inhabitants of it, becoming known as the Harbinger. Then, as part of O5-9's deal with the mirror entity, the Harbinger helped the entity escape its own doomed universe by taking possession of D-1989, before going back to sleep and allowing 507 to take back control of his body.
===Audiolog VNP-507-5386===
After the Foundation was dissolved into Vanguard, caused a Broken Masquerade scenario and integrating the anomalous world into the normal one, SCP-507 was redesignated VNP-507 and continued sharing what he saw in other dimensions but not only with Vanguard but also with the larger scientific community. One day, he went to an alternate version of the Wanderer's Library where he met a version of himself working for the Serpent's Hand as Agent Hopper. The two talked with each other, discussing the nature of their respective worlds, along with the alternate realities they had visited. Eventually, VNP-507 was forced to depart, biding Hopper farewell before returning to his reality and report back to Vanguard.
===Beyond the Rubicon===
One day almost all of baseline humanity went extinct due to a Calamity, leaving only the nonhuman creatures or abnormal humans. This included the SCP-507 who was also wiped alongside other humans.
