In will bryers x harem it would be cool to see Will absorb the mind flayer and its powers but what would be even more cool is that Will has some sort of secret power that even he doesn’t know about but when Billy and the mind flayer come, then he unlocks it and defeats the mind flayer and absorbs his power and saves Billy. you could make it where a very distant relative had the power that Will has but the power hasn’t been seen in generations until Will unlocks it . That seems like a very cool idea.
