it would be awesome if he got an authority from a witch factor epically the authority of greed

or maybe his ancestor is cumber

if you wanted to you could add the evil sayian transformation to the mc by having him eat too many of the fruit of the tree of might.

since you added aura from rwby to everyone they should naturally form a semblance.

reward Atlantean physic

reward anti magic grimoire from black clover

reward ultra ego form

reward iron dragon slayer magic

reward surgery fruit

reward mystic eye of death

suggestion for possible wishes 1. the knowledge of all magic from universe 7 so he could possibility get the knowledge of babid's mark knowledge to increase his strength and moro's magic of life absorption, 2. to unlock his potential to possibly get access to beast in the future,

name will be what you but my name suggestion is eis

oc suggestion cooler's son a frost demon with all 4 of frezia's forms plus cooler's fifth form, golden and black form so our mc can eventually absorb him

evil Saiyan powers would be awesome to add to him too being able to corrupt other people

sugestion for future character cards atom eve and duplikate from invincible and Marie Moreau and starlight or queen mave from the boys

if he got superman like powers than flew under a blue sun he could get superman vision and heal lana that way

their is also platinum kyrptonite if you want a cheaper way to get superman like powers or and even cheaper way to get superman powers have our mc buy an alchemy skill to transmute a regular piece of green kryptonite into a platinum kryptonite

suggestion third option save a few sayians and let the rest perish so you have a few loyal sayians to the protag like broly

4 if raven not already chosen

a suggestion maybe the mc should visit a planet with a blue sun to get superman vision to help protect his wives with adaptability the blue sun powers should last even if he goes back to a yellow sun planet
