Underzero is a WIP Au by us, (us being @sariels-world-ella and @strawberry-lemonade38 ) where the surface world was plummeted into a nuclear winter destroying most of the surface world, but the barrier managed to sheild the underground from the damage and radiation but plummeted them in a deep winter as well.
Grandpa Semi, based off the scrapped character from Undertale is the Grandfather of Sans and Papyrus who became their legal guardian after Gaster got scattered across time and space.
Gerson Boom, hasn't changed much from his Undertale counterpart besides the fact he is the roommate of Semi Serifs.

S: you know… It's going to get a lot colder… I don't think you should just wear only a scarf and gloves G: old sport, I've endured worse, you should know, you've been there. G: not like you are dressing warmly either, Semi S: well, I don't have skin it's not the same… ------------------------------------------------
Gerson: I remember when the surface was so alive and beautiful, it was very green, the skys were blue and it turned into beautiful reds and purples when the sun sets, there were gentle breezes and rejuvenating rain, fresh air, wildlife, I just wish humanity had appreciated it more.
Semi: Them's the breaks, Gerson
Gerson: is that the gross ketchup flavored coffee I told you to stop buying? S: Mhmm S: don't know why you hate it so much.
G: Semi, this is why Wingding never calls you.
S: No, my son Wingding never calls me because he's dead, I thought you knew that. S: And my grandsons call me at least once a month, if not more, Mr. Gerson Boom.
