@Samuel Measa If Kirby was going to be in a Death Battle, I'd rather see it against Galacticus since they have similar origins. I think a team up would be funnier. Kirby, Herald of Galacticus!
Jeff. You ate the power ups every costume hero gets to play with. Kirby eats those daily and fought things that have ended universes. Not 'could' end them. The entities had ended universes and still ended up in the Kirby serving tray.
Back away as you need another 10 year minimum at best.
Jeff, back away slowly. That is an eldritch being. The last survivor of the previous universe. The being that always hungers. The thing that can swallow anything. The being destine to swallow all in its ever growing hunger. kirby and Galacticus could form a survivor's therapy group.
