OK, so I need name ideas for the au and nickname ideas for sans. Here's some details that may help make the decision. OK, so it's a sans centric universe, the main story is about sans. The whole thing about this universe is that all monsters are on the surface and frisk has lost the ability to reset, but she could do it before. At the beginning, everything is pretty much the same as undertake, but a few characters have minor changes in personality. Sans still doesn't trust people well, he is a little depressed from events before the tests and the thousands of resets that frisk put him through. The only major personality changes is after the accident where he becomes a little more sad, but also becomes a little bit nicer and cares more. There is one major difference with him though, he isn't too lazy. He still falls asleep on the job a lot though. Paps is the same except he is a bit less optimistic and he worries about his brother more.
