Undertale OC Wiki

Judge!Sans is a Sans god like Ink, Error, Dream, etc. Basically, he judges you for every single action that you have made, and if he thinks that you are a truly bad person, he will delete your game. However, if he thinks you are a good person, he will simply do nothing but call you a hacker and congratulate you for getting through the multiverse. So in a sense, he's like the absolute final boss of a game, if a game included going through several Undertale AUs. He was made back in 2018.


Judge was made from a failed experiment when Dr. Gaster tried to make a synthetic human soul but wound up making a synthetic skeleton soul. Dr. Gaster did not repeat the experiment to try and not repeat the same mistake and make another skeleton soul. Dr. Gaster found out he had made a skeleton soul a few weeks after he put the synthetic soul into a container of nutrient fluid and saw a bundle of bones in the container, Gaster waited until the bones formed into a baby skeleton in which Gaster took a nearby blanket and took the skeleton out of the nutrient fluid and wrapped him up in the blanket. Gaster took care of the baby skeleton for five years, teaching him about the protector and the destroyer of AU's, basic math, science, and language.

Sans was happy with his life for about 4 years when Gaster said that he was going to be the judge of the AU'S, Gaster explained that Sans would have the power to let a fallen human pass through the multiverse unharmed if they were good or to destroy them and their souls if the human behaved poorly. Sans was both happy and nervous about the upcoming responsibility about becoming judge. Sans wondered if he would do a good job if he was judge and Gaster assured him that he would do a wonderful job.

As the next year of Sans' life approached, Gaster asked Sans if he would be ok living on his own, or if he prefers to go to an AU to be looked after by someone until he could fend for himself. Sans asked why Gaster had given him the options and Gaster bluntly told Sans that his time in the void was quickly coming to an end and that he would die in a week's time. Sans spoke in a disheartened tone that he would like the second option but asked Gaster if he could take a picture of him just to remember him by. Gaster had obliged and the two of them got in front of a timed camera and the two of them both put on the best smiles that they could. As the end of the week approached, Gaster took Sans to Undertale to live with the skelebro's until he could fend for himself, as they said goodbye, Sans said he would always remember him and Gaster shed a tear and said that he would always remember Sans, even in death. The two hugged and Gaster disappeared into the void where he soon became dust after a day.

When Sans moved into the skelebro's house, Undertale Sans said that Sans should have a nickname, Sans disagreed but eventually Sans agreed and said that his father might have liked to have Judge as a nickname. Undertale Sans agreed that it was a fitting name and Judge was glad. He lived happily in the Skelebro's house comfortably for about 13 years, being homeschooled by Sans when he wasn't selling hotdogs and being taught how to cook (albeit poorly) by Papyrus. Judge told the bro's he had to go to the void to learn how to be the Judge a couple months after his father promised he would become. The bro's were understandably pretty sad but understood completely and said that they hoped that they would meet again later and Judge said that they would always keep in touch through cellphone. After a few days of him packing and just being silly with his brothers he had a going away party with Sans, Papyrus, Grillby, Undyne, and Alphys. He bid everybody farewell the next morning and teleported to the void where he would learn how to use a few other powers.

Ink taught him how to see the statistics of anybody who came through the void, how to decide whether someone should pass through or not, and how erase somebody's game file. He was also taught other powers like how to look at other AU's and how to go to them, as well as attacks should a murderer come through the void. Judge understood every bit of information and kinda mastered magic.

Now Judge floats around in the void playing videogames with Dream when he had time and filling out small jobs just to get some gold to feed himself and get videogames. He is also happy with his spot in life currently!



Judge is a skeleton with black eyes and white eye-lights, he has an indigo hoodie with a dark indigo lining. He has a light indigo sweater, grey-indigo pants with light grey-indigo strips with less saturated indigo slippers. He has a decorative slash wound on his sweater with the words Spare and Kill on opposite sides on the jacket, as well as a flower sewn into his right slipper and a knife sewn into his left slipper.


He's laid-back and it's difficult to make him mad. He's pretty sarcastic and will often make jokes at someones expense. He's actually pretty caring though, and if you ask him to stop saying mean jokes about you then he will. Judge doesn't know what to do when someone is going through a stressful situation, this is due to his lack of empathy and his small amount of sympathy. For clarity, Judge only feels a handful of emotions, so he can't help anyone in a good way who doesn't feel one of the emotions he feels (he can help someone if they feel bored, but he can't help someone if they feel angry).

Even then, he can only hug the person or just try to talk it out with them. He does want to help people though, since he is very compassionate, he just doesn't know how to in certain situations.


Deleting someone's game files, floating around the multiverse, and re-coding game files. He doesn't really fight, so he just sends random pieces of code as attacks. He can also teleport in and out of the Anti-Void, and he can teleport to any AU if he so chooses.

  • Judge can only feel a few emotions, those being: Distaste, boredom, sadness, joy, disgust, content, and fear.
  • He's pretty much neutral with everyone in the multiverse. Not really having best friends.
  • Judge will most likely not have a debut comic. He may only show up in asks.
  • He has a few drops of determination in him due to determination being in the mixture that was supposed to create a synthetic human soul.
  • He doesn't hate a lot of people simply because he can't feel hate. He can dislike a lot of people though.
  • Judge is also Aromantic Asexual. Meaning he doesn't have crushes and he doesn't like romance, he doesn't get what all the hype is about romantic relationships. He is fine with friendships though, and he cares for his friends and family. He's tried to date in the past but eventually found out he didn't like dating, his exes didn't become friends with him though, but he doesn't really care.
