In one of my AU's, Undermind, he's ma S4nsy bab~ Name: S4ns Age: ??? Species: Skeleton/Glitch Backstory: He was once a regular Sans, only wanted his brother to have a real father. He went back in a time machine to save him. Unfortunately, something went wrong- when he was saving his father... he was pushed in as well. He saved him, told him what happened, and then glitched into the younger Sans's mind for eternity. Though he can teleport to other AU's for a while without being seen, he will get weak if he doesn't go back for a while. And since the younger Sans was the one who pushed him in, (Or Kristen,) he found a screen, and he's able to torture him through it. Goal: To live free and fully again, someday...
