Just to clear anything up, Mahito isn't actually a person, he's a cursed spirit. He looks like a person because he's the embodiment of human's hatred for each other. Greed, cruelty, arrogance, he represents all of that. His power is called Idle Transfiguration. It allows him to touch people's souls and change their shape, which is how he turned all those people into monsters and turds. He can also change the shape of his own soul, which lets him shape-shift, and he's immune to physical damage as long as it doesn't also hit his soul.
All my homies hate mahito and I'm glad to call them homies, (he is a W villan tho ngl) and I can't blame Kidd for liking him because his powers are pretty cool, but If y'all watch JJK y'all will definitely understand 😂
Also I did see that even tho cj didn't show the all the context behind every clip, Cee was ecstatic whenever mahito got his ahh beat so imagine with it😭
