Pretty much a marks that goes through what happens in the comics but when he's emperor and really old that he has gray hair and everything his universe starts collapsing for some reason and eventually when he's that last living thing he gets sucked up by a portal and his looks are deaged but has all the strength that a viltrumite would have at his actual thousands of years of age would have and sent to the past or a different dimension all together and see what he gets up to maybe he's a darker mark who replaces that universes mark or goes to deal with thragg early and takes over the empire or just lives his life and interferes when he feels like it
