Just an advice, as a veteran Novel reader and relatively experienced fanfic reader i would advice you that you souldnt keep your focus on beings evolving due to his energy(that occurance itself was a mistake in my opinion) because it gets Boring pretty fast and fans of marvel comics/ mcu may not like it because if world got a powerup like that og characters need powerup too and it makes everything messy(as if it isnt in og) so my idea make that energy disappear after a short time( you can use excuse of it being limited) as for mutated beings you can make MC took their energy(suck them off lol) because even if its diluted it is his energy after all.. After that of along the way MC can build his little custodes army lol
