Twenty-Fifth: FGOD Error Beginnings:
Geno
Strings
TK
Classic Sans
Classic Papyrus
Chara (If this is a Human FGOD Multiverse)
Others (Aside from Geno, Strings, and others that have already been done at least once)

I have personally done Geno and TK. I don't mind Strings as a background, but some variety in who became what would be amazing. Feel free to offer others who haven't been done much (I've seen Lust -> Error)

I don't really have much to say on this. This is more just a fun thing to think about and adapt. I know canonically Geno -> Error, but FGOD Error is already a massive jump from canon, sooooooooooo
