Sans/WiseTale

==Backstory==
Sans is a skeleton who is a scientists and a co-worker for Gaster. Sans lives in the Underground, but in his younger days he met a human named Aqua. Sans helps Aqua and shows her to his house in Snowdin. Gaster was Sans's caretaker at the time and was hesitant at first about letting the human in, but with some thought he let the human stay. Sans and Aqua were the best of friends playing together and enjoying each other's company. Gaster is relieved that they became good friends however, Aqua only stayed for a few days as they both said their farewells. Sans never sees her again.
Many years later Sans becomes a scientist and co-worker for Gaster helping him on various scientific projects. However, once the sixth human who falls down the Underground after Chara arrives a civil war starts. Sans and Gaster along with the help of Alphys were on a rescue mission to save as many monsters they could possibly can no matter which side they were on. After the death of the sixth human and the war ending Gaster reveals that the human created the war which shocks and infuriates Sans.
Sans has a change of heart about humans seeing how dangerous they are and the damage they could cause to the Underground. Sans helps Gaster and Alphys create machines to strengthen monsters he also helps Alphys to create the body of Mettaton the killer robot. Sans and Mettaton were good friends as Sans helps him in the entertainment business making Mettaton a star however, this is the start that broke their friendship. Mettaton becomes more focused on his audience than his friend and Sans becomes afraid of losing his friend. Sans did what he could, but in the end they drifted apart making Sans depressed.
Soon though Sans then hangs out with Alphys watching anime and relaxing enjoying each other's company however, one day the seventh human who falls after Chara arrives. The scientists united their minds and efforts in stopping the human and his carnage. Sans and Gaster have a lot of debates on how to stop the human, but despite that Sans mainly goes on rescue missions to save monsters and occasionally monitors the human. Sans wants to stop the human however, Gaster advises him not to face the human to Sans's reluctance. 
Sans helps Alphys with the experiments with Determination to save monsters from their deaths, but they were mainly unsuccessful. Sans becomes desperate and injects Determination into all of the patients despite Alphys's warnings. Fortunately all the monsters recovered to their relief. Gaster is slightly disappointed in Sans not knowing the consequences, but at the same time is proud of him as he might of saved their lives. Gaster then lets Sans face the human advising him to use the blue bone attack to capture the human which Sans gladly accepts the mission.
Sans teleports to the Last Corridor and waits for the human to arrive which he eventually does. The human warns Sans, but he confidently believes that he can capture the human. The battle is long and intense however, in the end Sans is the victor capturing the human in a blue bone prison. Gaster teleports behind him needing his help, but to let the human go which surprises Sans. Gaster mentions it's about the patients he injected with Determination and with some persuasion he reluctantly lets the human go and teleports back to the lab.
As Sans and Gaster return to the lab they went to the bed chambers as Sans sees the amalgamates that he accidently created. Sans horrified with his failure teleports away to a dump in Waterfall along with the diary that contains all the entries. Sans wrote the last entries before Gaster eventually finds him, although Sans wants to be left alone Gaster admits both of their mistakes and persuades him to stop the human once and for all. They both teleport back to the lab as they and Alphys discuss a plan to stop the human. 
As Gaster teleports to the barrier Sans and Alphys made the preparations and once Gaster and the human teleport inside the Determination Extractor room they locked them both in. Gaster then overloads the Determination Extractor to Sans's horror as he tries to save Gaster, but he uses gravity manipulation to push Sans as far as possibly could to protect the skeleton. Sans hears Gaster's final words saying the Entry of number 17 before the Determination Extractor fired as a part of Gaster infuses with Sans and the whole world turns to white. Sans then continues his life in the original universe of Undertale gaining new power, a brother and humour until once again he faces the seventh human, but the human is not the one he knows of.
==Profile ==
===Appearance===
Sans is a skeleton who wears a long white lab coat that is slightly bigger than his size. Sans wears a scruffy dark navy blue t-shirt, but he also wears black formal trousers and black shoes. Sans's eyes are white when he is in a neutral state however, that can change once he is in battle and using magic which turns the colour of his left eye to yellow as the other is just a black socket.
===Personality===
Sans has a much more serious personality as he is very easily agitated when something does not go his way and he hardly ever makes jokes as he is more focused in finishing his tasks. Sans will follow Gaster's orders even when he entirely disagrees with him, but this can often leads to arguments later on. Sans at times is lazy and enjoys the company of others, but in stressful situations Sans can get depressed and will loathe himself if he cannot save others from their demise.
==Soul==
Sans has a monster's soul and he is capable of using magic mainly to summon bones or teleport.
==Abilities ==
Bones: Sans has the ability to summon bones at will and launch them like projectiles at his opponent. Sans rarely uses this ability because of his research and various other scientific projects, but he does use this ability quite often when he fights Krotos the seventh human who has fallen after Chara.
Blue Bone Attack: Sans can summon blue bones an attack that will not harm a user unless they move. Sans uses this ability to capture someone or to prevent people from entering, but it is also quite rare for him to use this ability unless under stressful situations. 
Teleportation: Sans can teleport anywhere in the Underground as long as he can imagine the place he is aiming for. Sans uses this ability on a daily basis whether for rescue missions or to go to a place he desires. Sans uses this ability quite often during the civil war and the rampage of the seventh human who falls after Chara.
== Weaknesses==
Depression: Sans can get easily depressed when stressful situations can get out of control and there is nothing he can do about it. Sans will loathe himself if he cannot save others from death or worse make them suffer a terrible fate that even death cannot save them.
Anger issues: Sans can become easily angered when things do not go his way or disagreeing with someone in tense situations. Sans's anger at times can make him irrational and spiteful becoming prideful as well in the process. Despite this he can control his anger and do what he is ordered even if he disagrees with it entirely.
==Relationships==
===Gaster/WiseTale (Friends) ===
Gaster was once the caretaker of Sans, but now Sans works for Gaster as they work together on various scientific projects. Gaster apricates Sans for helping him with their scientific discovers even with their differences. Sans although he can a bit angry with Gaster at times they can still crack a joke and laugh it off, but in tense situations they always have each other's back even when they disagree. Gaster always considers Sans a friend and vice versa and hopes that one day that he, Sans and Alphys will see the sun once the Underground has been set free.
=== Alphys/WiseTale (Friends)===
Alphys is friends with Sans as they watch anime together, make terrible joes and just sit back relax on the couch. Sans helps Alphys make Mettaton's body and it was a proud moment for them both once they created it. Sans enjoys Alphys's company as she does not boss him around or ask him to do anything for her while Alphys apricates Sans for just being there to cheer the mood and have a good time. They both have a better working relationship than they have with Gaster since they spend time together away from work.
===Mettaton/WiseTale (Former Friends)===
Mettaton was once friends with Sans as they both made jokes and spent time together, but all of that changes when Sans helps Mettaton become a star in the entertainment industry. Mettaton becomes more obsessed in entertaining his audience rather than keeping his friendship with Sans which made him depressed. Sans tries his hardest to maintain their relationship even going so far to put faults in Mettaton's body so that he can still see him. Eventually their friendship was no more as they are now nothing more than acquaintances. 
===Asgore/WiseTale (Acquaintances)===
Asgore meets Sans occasionally with Gaster although he does not know Sans on a personal level he is just glad that he helps Gaster to break the barrier or help his people. Sans does not know Asgore very well other than that he is their King, but he likes to give him the name King fluffy buns as a joke due to his appearance. Asgore and Sans are on friendly terms even if they do not see each other that much.
===Aqua/WiseTale (Friends)===
Aqua after a long journey to Snowdin gets a hand up from Sans when he is a child and takes her to his house. As they enter Sans asks Gaster if she could stay for a few days although Gaster hesitates he then agrees to Sans's relief. Aqua and Sans were the best of friends telling jokes together, going to Grillby's together, and spending time together. They both said their farewells as Gaster teleports himself and Aqua away and Sans never sees her again, but once he found out he is sad however, he also understood why it had to be done as he wishes that she could have stayed a bit longer. 
===Violet/WiseTale (Enemies)===
Violet and Sans barely knew each other as they did not have time to properly know each other since there is a civil war going on in the Underground. Violet has a hatred for monster kind so she caused as much havoc throughout the Underground disregarding the lives of monsters. Once the war ended and Violet deceased Gaster reveals that Violet is the one who caused the war which surprises Sans. This revelation changes Sans's viewpoint on humans seeing them as a threat to monster kind and if he realised this sooner he would have stopped Violet where she stood.
===Krotos/WiseTale (Enemies)===
Krotos fears and respects Sans because of his power and resolve in trying to stop him and he would have succeeded if not for Gaster's interference. Sans despises Krotos because he is severely injuring monsters to the point that they are crumbling to dust. They both fear each other because of their capabilities, Sans because of his magic and exploiting weaknesses and Krotos because of his perseverance and adaptability. Krotos's rivalry with Sans is intense, but it is only second to one. 
==Trivia==
* This is the first WiseTale character that has an image for the character.
*Sans's parents passed away while he was young so Gaster becomes his caretaker until he could stand on his own two feet.
*Sans does not know Toriel until after the events of WiseTale when he has forgotten about Aqua, Violet and Krotos.
