they're both ultra important and integral to the lore but we know fuck all about either of them

chara was some kid who was heavily abused i guess and tried to an hero but wound up being raised by goats, eating chocolate, playing with knives and liking big numbers because they conflated getting stronger in video game rpgs with getting stronger irl somehow, then died, then uh i guess maybe kinda haunted frisks's body when they found down 100 years later and uh idk weird le epic creepypasta stuff happens with them that's still COMPLETELY confusing and unclear if you go full geno. but tl;dr without them there'd be no undertale

gaster is some dude who did some epic inventions and then made deltarune and we know literally absolutely nothing beyond that whatsoever for sure but we are one hundred percent certain that without him there'd be no deltarune and very likely no undertale
