i drew what age swap sans looks like out of gacha. also wrote doen facts about him!
some more facts!
if his frisk did a genocide run that he somehow survived and core frisk offered him to go to the omega timeline it would take him awhile to stay full time. aka he'll go there but probably go back to his own timeline untill he is fully use to it. but a papyrus being around him in the omega timeline will help speed it up.
he does drink things like ketchup, mayo, relish and mustard but he favors hot sauce and energy drinks.
he can't stand anything Slimey, so its hard for him to help with cleaning the true lab.
unlike classic sans his room is pretty clean. easy there is a pill of blacknets but its what he hides in after a long day.
he struggles with his hunger cues and self care so he needs papyrus or someone to remind him to shower and eat.
age swap can and will go completely mute if he feels stressed out or flustered.
his sleep schedule is so out of wack. he has also went week without sleep and functioned perfectly fine untill he was walking him with past undyne's house to go back him, and he passed out. lets just say papyrus had to call alphy and asgore telling them sans will be taking the next week off weather sans liked it or not.
his au is one of the easiest to get with, and the other residents of his au are extremely welcoming of outsiders, more so towards the dark sans. much to dust and horror's surprise..
that being said his au isnt Intiarly unwelcoming to the star sanses or other "good" sanses.. sans and papyrus are pretty Nurtral about both sides.
age swap sans has a dot in the middle of his spine with little lines coming from it. that's the scar from the accident on take your kid to work day.
