Heritage for the Future/Evil Incarnate DIO

Evil Incarnate DIO (邪悪の化身ディオ), or "Shadow DIO" in the English localization, is the form DIO takes for most of Part 3 while waiting for his body to completely assimilate. To reflect this, his moveset involves mainly open-hand light and heavy attacks (which ties into how weak the left side of his body was if Dio happens to have his animations be performed when facing right).

The World in this form, is also depicted as a faint-and-clear silhouette.

Moveset and Gameplay
In the game where Active Stands are prevalent, Shadow DIO is a passive Stand user. He can deal a lot of damage with full offensive attacks without an Active Stand via a solid amount of frame-traps and pseudo-disjointed pokes with his silhouette-version of The World, even though he lacks the more defensive and utility-type traits of having an active Stand. His Stand attacks are effective as surprises, and capable of juggling and/or short bread-and-butter combo finishers. Combined with his own attacks, he deals a lot of damage in a short time, more so within The World, when he stops time.

Story Mode
His Story Mode in JoJo's Venture has him simply face off enemies until reaching Jotaro, with no storyline involved. In Heritage for the Future, the incarnation of evil, DIO awaits the arrival of the Joestar Group to annihilate his adversaries and become the ultimate being. Evil Incarnate DIO only appears in Kakyoin's Story Mode as the first stage, and Hol Horse's as the final.

In Super Story Mode on the PS1 version, after finishing Super Story Mode once, four extra stages are unlocked, adapting various characters' encounters with Evil Incarnate Dio.
