Diavolo/Abilities and Powers

Personal
Transformation: Despite likely being human, Diavolo and Doppio share many minor abilities in changing their physical appearance. Doppio looks around 17 despite Diavolo chronologically being 33 and shorter than Buccellati, but while attacking that same man Diavolo appeared to be a head taller if not more as well as being muscular as former protagonists like Joseph - however, during the battle in Rome, Diavolo was roughly around Mista's height. As well, when Diavolo takes over, Doppio's freckles disappear and his voice deepens, and it may be possible that his hair can become longer or short than Doppio.

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.
