Maybe one of the coolest splatfest?

Inkmatas
Worked for her power
Has motivations
Never stole
Learned her magic
Doesn't hurt anyone innocent
Isn't a god but can rival gods
Has actual magic

Eggyhead
Was born with all of his abilities ready
Doesn't have good enough motivations
Has stole
Never learned how to use his magic (he had already mastered it)
Hurts innocent people
Is a god
Has "Magic"

Collector
Has a crystal that powers all of his powers
Has motivations
Maybe stole (Idk if he technically stole the crystal from the banisher)
Learned his power
Doesn't hurt innocent people
Is a god (His power rivals gods so he's a god)
Doesn't have magic

im either going with Inkmatas or the collector
(i don't want Eggyhead to beat the crap out of me for no reason)
