Diavolo/Abilities and Powers

Personal
Transformation: Should Diavolo ever take over Doppio's body or vice versa, multiple physical changes occur. Doppio, when taken over by Diavolo, rolls his eyes back to reveal Diavolo's fragmented eyes and gains a larger muscle mass and height. Doppio's freckles also disappear and his voice deepens. Later on, when he attacks Polnareff, he removes Doppio's sweater to reveal untied and long hair, dotted now with spots.

Stand
Diavolo's humanoid Stand is King Crimson, of immense offensive power; also enabling Diavolo to foresee and bypass events of his choice occurring within a time frame of ~10 seconds.
