Dr. Sack

"I've always viewed myself as a man of science...but when you live in a world of gods & monsters, mysticism is too hard to ignore."~ Zack to Michael Myers in A Spooktacular Halloween.Dr. Zackary Vore, commonly known as Dr. Sack was once a friend of the infamous Dr. Victor Zolostene, both of whom worked together to find the secrets to immortality during the Black Death. In the modern day, Zack worked as a psychiatrist at Blackthorn Asylum, a place which was meant to rehabilitate the weirdest of the weird. After a horrible breakout happened, the asylum was shut down & he fled to find other means of work, with him aiding the Monirken Empire in thwarting the many nefarious world-ending schemes of the Deep Creeps. Despite appearing later than most of them, he is among the main characters in the Terrachaoverse series.
Tier: Low 7-B; High 5-A with the Sickening Sickle; at least 5-B with the Shadow Pumpkin
== Appearance ==
Zack appears as a man of below average height wearing a black suit jacket, black or dark gray pants, a burlap mask with sharp teeth, & a noose in place of a tie. The noose in particular is what was originally used to hang him, but he kept it as a souvenir since the hanging failed, wearing it as a sign of his immortality. He typically wears a collared shirt, usually mint green, but he's also worn purple, red, & leaf green shirts.
== History ==
=== Early Life & Quest for Immortality ===
Zackary Vore was born somewhere in England on November 10th, 1317. He lived next door to the Zolostene family, & he became a good friend with their son Victor. Both of them shared an innate pursuit of knowledge & curiosity about the world. Zack saw Victor as someone who was very intelligent like himself, so they bonded quite naturally, which was rare considering how sheltered Victor was, evidently surprising his parents. During their young adulthood, they would excel in different fields of science, & feeling afraid of getting older & losing the wonders of youth, they sought to discover the secrets to immortality. While Zack would bring about a more scientific means to creating an age-defying serum, Victor believed that mysticism would be the deciding factor, & the two would embark on a quest to find the legendary Fountain of Youth.
Decades would pass & by 1346, Europe & even some of Africa & Asia were engulfed by the Bubonic Plague. Hundreds of millions of people had met their end to this pestilence, but Zack & Victor found themselves rather lucky during this pandemic. They had caught wind of the Black Death while they were in northern Africa, where they actually managed to find the mythical Fountain of Youth somewhere in what used to be Mesopotamia. Victor had no intention on sharing the elixir of life with anyone other than those he deemed "deserving" of it, while Zackary would have more generous intentions. Regardless of their differing views, the two returned to England with some of the water they collected, covering their tracks along the way. Understanding that prolonging life to the extent of the water's properties would cause Humans to proliferate out of control, they would only share minuscule amounts of the water with whom they would share it with. Victor only gave it to those he deemed the smartest & the strongest, while Zack simply wanted to help anyone he could. The Black Death would end in 1353, but the Bubonic Plague would still return at later dates in history. 
Decades & even centuries would pass by, with Zack & Victor's drinking of the fountain's water proving to be successful as neither of them had hardly aged past their thirties. During this time, Zack & Victor had still kept in touch every now & then, exchanging scientific & magical information with each other to even further their evolution. In the 1600's, the two went their separate ways as Zackary moved overseas to what would eventually become the United States. Near the end of the century, people had found out Zackary's true identity & accused him of practicing witchcraft, evident from his inhumanly long lifespan. A trial had occurred in Salem, Massachusetts, & while Zack confessed he had used some mysticism among his predominately scientific research, he made sure out of the kindness of his heart that the name of Victor Zolostene would not even be whispered of. The trial had ended & Zack was hung at the gallows, but instead of dying, Zackary did something that made everyone's blood run cold; he tilted his head up, grabbed the rope above him, & lifted himself out of the grasp of the rope, leaving the crowd running & screaming in fear. Zack had become somewhat of an urban legend, recognized as the Man they Could Not Hang. Zack later went into hiding & built an elaborate underground home for himself in an unspecified location. 
=== Adapting to the Times ===
Finding new purpose in the modern world, Zackary became intrigued by how Humans were advancing as a species & decided to start studying the mind. He would even study at Miskatonic University in Arkham, Massachusetts for a few years, primarily focusing on psychology & psychiatry. Not to mention, this time he actually felt welcome in this State. Time went on & he eventually signed up as a psychiatrist at Blackthorn Asylum in 1992. This was no ordinary asylum, as it was a prison for the most dangerous outcasts, often spoken of in scary campfire stories as a place where monsters go. Only the weirdest of the weird were committed here, & Zackary used all of his brain power to help these tortured souls to the best of his ability. This is where he became known as Dr. Sack, as he would wear a burlap sack over his head when interacting with his patients, putting their minds at ease if they were afraid of being gazed upon by judging eyes.
Eight years later, Zack had found out that Victor Zolostene had moved to the States, & while Zack believed this to be a sign of a friendship being rekindled, it was anything but. While Zackary was amused by how much humanity has evolved since the days of the Plague, Zolostene became extremely contemptuous of mankind, enforcing natural selection at any given opportunity through a team he was building up called the Deep Creeps. The two doctors officially had a falling out when Zack refused to join Zolostene, going their separate ways for good.
Continuing his work at the asylum, Zack would find that some of his patients were abnormal in a way he would especially find interest in, for they were of the supernatural. He knew of their existence thanks to the Deep Creeps' roster, & he would go out of his way to pay even closer attention to these abnormal patients. One in particular, Michael Myers had become a regular attendant to Zack's sessions. Zack knew well about the murders Michael had committed in his youth, but would struggle to find out why he does what he does, mainly because Michael doesn't speak. In 2012, Michael had escaped from the asylum by participating in a massive breakout. Zack had lost many of his patients in the process & was fired due to the staff believing he seemingly enabled Michael by wearing a mask in their sessions, as Michael himself was also fond of wearing a mask himself. Zack would then go into exile in his underground base. 
On August 14th, 2017, the Deep Creeps had launched an attack on Zack's underground base, with Hogulus Decimus, Bruce Carnus, & MORTIS destroying everything in sight. Zolostene stood over Zackary, crushed by the rubble, saying a few parting words before leaving him for dead. However, the Deep Creeps were overconfident & did not think that Zack had an ace up his sleeve, for he would escape from the debris & secretly follow the Deep Creeps through the Internet, catching wind of whatever heinous schemes they might be up to. 
=== Returning from "Death" to Save the World ===
On Halloween morning, Zack witnessed a portal to the Redimension open somewhere in Herkimer, New York, with the Deep Creeps emerging alongside a terrifying monster simply named the Beast. Zack overheard enough about their plans to formulate a plan of his own & go find the most powerful supernatural beings in the world to work together & stop the Beast from ending all life on Earth. Luckily, since MORTIS was partially leading this operation to settle a personal score, Zack was able to get a somewhat precise lead on where to go first. It took some time, but he made his way to the Ledda Residence, where he introduced himself to Almighty Tallest Daniel Ledda. Dan was initially weirded out by Zack's nickname, but gave his full attention when Zack mentioned that he has valuable knowledge about the Deep Creeps & what their latest scheme is. Going inside, the two sat at the dining room table, where Lord Claudius Ko'Al & Princess Twilight Sparkle overheard their conversation. Zack explained how he was able to survive his alleged deaths, his past with Zolostene, Zolostene's misanthropic ideals, what the Beast is & what he's destined to do, & even let Dan borrow his thumbdrive which contained top secret photos of the Deep Creeps' current base. When Zackary finished his exposition dump, Claudius chimed in to announce he'd be helping Dan with the inevitable battle against the Beast.
Sometime later that afternoon, Zackary & Claudius had contacted as many people available who could help fight the Beast when he arrives. Zack returned to the Ledda Residence & joined in a conversation between Dan & Asmodeus, the latter being surprised that Zack is still alive. Dan explained that he believed the Hexacontakis should be used to send the Beast to another dimension through the Dimenchamber, but was dismissive when realizing the Deep Creeps might already know about the many dimensions of the Multiverse. Luckily, Claudius chimed in & said that Juvenile Batman was working on a device to attach to the Dimenchamber that can scramble dimensional coordinates, which gave Dan more confidence in his plan. However, when Asmodeus sensed Twilight resting down the hallway & suggested she help out, Dan adamantly refused to put her in any danger. Zack disagreed & stated they must use every resource available to achieve victory, but Asmodeus tried to convince him not to have Twilight join in. Zack left the conversation after showing Dan a list of everyone else to be involved, with 23 entities total, including Unwoak who was also overhearing this conversation.
As night fell, everyone got ready in their positions. Zack, Asmodeus, & Imhotep briefly spoke to each other, with Zack relaying the entirety of the plan to Asmodeus. Once Darths Vader & Kaidus lure the Beast into the basement with the Force, they & everyone else in the house will weaken him to the best of their ability & finally push the Beast upstairs, where Dan will fight him & send him through a dimensional warp. He also explained to Asmodeus what the Beast actually was since he forgot, & when mentioning the fires of Hell, he asked Asmodeus what being the embodiment of a deadly sin was like. Asmodeus did not want to talk about this, so he simply stated he'd tell him that another time. Eventually, the Beast had arrived, taking many lives along the way & working his way up the house from the basement to defeat anyone who stood in his way, searching for the most powerful being present. Zack noticed that Dan was somewhat struggling against the Beast, so he leapt into battle with his sickle to do some minor damage to the Beast. Zack was swatted away & knocked out cold, but his distraction gave Dan just enough time to prepare for a few more attacks. When Dan was running out of options, Asmodeus, Jackhotep, Sdrawkcab, Big Fat Ugly Bug Faced Baby Eating O'Brien, & Twilight came in to fire their strongest attacks at the Beast. Dan saw an opening & unveiled a nearby curtain that activated the Dimenchamber, scrambling the Beast's atoms across the Multiverse. Zack regained consciousness when he heard the sounds of energy beams & roaring, declaring victory as he saw that the Beast was gone. Asmodeus counted the eight souls who gave their life to stop the Beast, with everyone mourning them. To lighten the mood, O'Brien reminded everyone that it was still Halloween & that they should be celebrating the spooky holiday along with their victory. He also reminded Dan of a certain clown who'd be making appearance tonight, to which they all went outside to watch Pennywise perform his Dance of Doom.
MORE TO BE ADDED SOON(ISH)
== Personality ==
Zackary is driven by his curiosity & intellect, as he finds the mind to be a fascinating subject. This is what led to him becoming a psychiatrist, & he finds the minds of supernatural beings to be even more intriguing since they are more free than the average person is, unbound by societal norms. When having sessions with his patients, he wears a mask to give them a sense of comfort with anonymity; with no face to be seen, any fear of being judged is reduced. However, he's taken a liking to wearing this mask anyway considering that his experiments led to his face becoming disfigured. 
In his youth, he was scared of getting old, which led to him & Zolostene discovering how to become immortal. However, unlike Zolostene who grew to hate mankind as it devolved around him, Zack was more optimistic & saw the good in man's evolution while also acknowledging the negative effects of it. Zack also likes to write poetry, specifically about human nature, the mysteries of the mind, & the instinctual desires that we all have. He can also be a bit of a goof sometimes, as he humorously waddled away from Blue Shirt Shaggy & Han Velsing after the former unmasked him, & he repeatedly slammed his head on the keyboard of an old, unresponsive laptop in Enter the Spooks. His sense of humor can sometimes be morbid like in The Impression of the Doki, but it can often complement other characters' humor like in the Doki Doki Literature Empire trilogy. 
== Powers & Abilities ==
=== Physical Abilities ===
Superhuman Strength: While not much of a physical fighter, Zack has shown that he is willing to throw down if necessary. He may be old, but he still has a good swing to his punch, as his experiments have ascended him beyond human. His one feat of strength was that he was able to inflict minor damage onto the Beast, but this is only thanks to him wielding the Sickening Sickle. His normal strength is unknown, though he believed he would be able to fight Leo Panthera & Michael Myers, & the latter actually did harm him by flipping a desk onto him once. Given that it took almost a minute for Zack to recompose himself, he'd considerably be behind Michael in terms of physical potential.
Superhuman Speed: Zack has comparable speed to Jack, as he was able to run alongside him from an unspecified forest to the Ledda Residence, giving him transonic moving speed. He was also able to swiftly dodge Jack trying to strike down the Shadow Pumpkin with the Hallows Blade, placing his combat/reaction speed in the massively hypersonic range. He can also waddle away like a crab if he needs to make a quick exit.
Durability: Thanks to his scientifically-enhanced physique, Zack can take as much damage as he can give, which is notably behind Michael Myers' level of toughness. However, it is known that he cannot be killed by suffocation/asphyxiation, as hanging him does nothing. He also once survived the Beast casually backhanding him in the face, although it knocked him out unconscious & he was amped at the time by his sickle. He was even capable of briefly wielding the Infinity Gauntlet, which could be an outlier, but it's likely he was holding his sickle off-screen or at least had it in his coat.
Immortality: Through a combination of science & magic, Zackary has become immortal in that he is immune to dying by old age or disease. 
Haunting Visage: While not really much of a superpower per se, when unmasked his face can intimidate others rather easily. Even Blue Shirt Shaggy & Han Velsing, both men who have seen their fair share of monsters over the years shrieked at his appearance when Shaggy unmasked him. 
=== Special Powers ===
Superior Intellect: Zackary has a degree of knowledge in regards to the link between mental & physical problems in one's being, mainly the mental ones. He's studied many minds throughout his career from all sorts of ages & varying levels of sanity. He's often contemplated being a psychologist instead of a psychiatrist, but he does like to delve into the physicality of mental issues. His knowledge & wisdom are also reflected in his poems. He was also smart enough to fake his death on multiple occasions, once when he was hung at a witch trial (or rather, warlock trial), & another time when the Deep Creeps destroyed his underground home.
Alchemy: Back when he was partners with Zolostene, he introduced Victor to the science of alchemy, which allowed for him to become immortal by stopping his body from aging & deteriorating past a certain age. He would also use his alchemic skills later in life to forge his own medicines that he'd give to his patients.
Dark Magic: Zack is a man of science first & foremost, but thanks to Zolostene he has some knowledge of the mystic arts, which he's kept in a leather notebook of his. Although, it seems he's forgotten most of what he's learned, as in Enter the Spooks he said he was hoping to find some "cryptic words in Latin" as opposed to knowing that he'd find a Latin spell.
* Cloaking Spell: By uttering the chant "Evanescere, evanescere, in tenebras evanescere! (Translation: Disappear, disappear, into darkness disappear!)", he can hide the power signature of a person or object. It could even work on a powerful vessel like the Shadow Pumpkin, as it was made completely undetectable to Jackiller's Spook Charm.
== Equipment ==
Spellbook: Being the accomplished scholar that he is, Zack brings a leather notebook with him most places he goes to. He jots down his notes with a golden skeleton pen, writing down whatever he finds to be useful information. This book contains handy reminders, records of sessions with patients, scientific research, & most dangerously, spells. 
Sickening Sickle: A weapon given to him by Zolostene, this sickle is made out of an unknown metal & a wooden handle. He has only been shown using offensively in one instance where he briefly distracted the Beast by cutting into his shoulder. However, it cannot break through magical barriers. It also gives Zack enhanced durability, as well, able to make him far stronger on a level similar to Darth Kaidus. Since it was likely on his person when he briefly tried on the Infinity Gauntlet even when he was not carrying the sickle, we can infer that it gives the wielder some kind of aura that temporarily lasts even when it's not in his hands. He upgraded it sometime in 2023 to have a chain attached to it so he can swing it around & keep it on his person easier. 
The Infinity Gauntlet (formerly): When Dan tasked him to guard the Infinity Gauntlet in late 2018, he was briefly able to try it on. The only thing he did with it was use the Reality Stone to create a chromithian pear out of thin air. He then returned it to its post. Do note that Zack does not get a separate key in his tier because of how short his wielding of the gauntlet was.
The Shadow Pumpkin (formerly): From late 2018 to late 2021, Zack was the owner of the Shadow Pumpkin, one of the most potent sources of dark magic in the world. As someone more attuned with science than magic, he had a hard time properly utilizing its powers. He eventually gave it to Jackiller after being convinced by Jack to return it to its home universe. These are not all of the pumpkin's powers, but they're the ones that Zack himself used while owning it:
* Transformation: The pumpkin can revert someone to their true state if they're wearing a disguise, or they can revert someone to their original state if they were already transformed into something else.
* Power Bestowal: The pumpkin can supply vast amounts of power to whoever the user directs it to. This was able to restore Equinox to his full power, meaning the pumpkin has the potential for world-ending feats. It was also able to give Scarecrow back his power, though at the cost of his intelligence & sanity.
* Umbrakinesis: The pumpkin can grant the user control over the element of darkness.
** Shadow Tendrils: It can release several tendrils of shadow energy to grab or lash out at opponents.
== Weaknesses ==
Despite living in a world of gods & monsters, Zack has hardly ever relied on his powers & abilities to survive, mainly surviving due to his clever intelligence. He has little to no actual training in physical combat, which is why he chooses to solve his problems mentally instead of physically, more often than not threatening/intimidating his enemies instead of actually fighting them.
== Trivia ==
* His name is a reference to Dr. Sack from The Filthy Frank Show.
*He is left handed, as seen when he was writing in his notebook in Carving Out the Mystery.
*For unknown reasons, his mask often squeaks when squished.
* His title of being "The Man They Could Not Hang" is a reference to the 1939 film of the same, as well as Ygor from Son of Frankenstein, who also survived being hung. Not to mention, his quote about "gods & monsters" is inspired by a quote spoken by Dr. Praetorius in that film's predecessor, Bride of Frankenstein.
* The name of the asylum he worked at is derived from an album by Nox Arcana, the music from which often plays when he is on-screen. 
* His favorite character from Doki Doki Literature Club is Sayori.
