Devo

Devo the Cursed is a minor antagonist appearing in Part III: Stardust Crusaders.

Appearance/Personality
Devo is a tall Native American with long dark hair. His face and body are covered by countless scars: the results of Devo letting his opponents attack him in order to make his anger and his stand's power grow.

At first, Polnareff believes him to be a complete idiot, since Devo was hiding in the fridge of Jean Pierre Polnareff's room and left all the drinks outside, above the very fridge, making himself easily detectable. However, that was part of Devo's plan, as he intended to be detected by Polnareff and hit by his stand to activate his anger.

History
Prior to allying with Dio Brando, Devo was already known all over the world as a lethal assassin. It seems that he was able to use Native American magic and that he had worked for Mafia organisations, armies and governments from any part of the world. According to Mohammed Abdul, any person who has seen Devo's stand's power has been killed, leading ordinary people to believe the victims were cursed and them giving Devo the nickname "The Cursed'.

Stardust Crusaders (1987)
Devo ambushes Jean Pierre Polnareff in his hotel room in Singapore, tricking him into activating Ebony Devil's power by hitting him. He then escaped from the room, found refugee in a toilet stall and tried to kill Polnareff from there by possessing a doll with his stand.

Though Ebony Devil managed to tie Polnareff under the bed, so that he couldn't properly use his Silver Chariot, the Frenchman was able to destroy a mirror and use the reflection of its fragments to finally counterattack Devo's stand. Polnareff asked for information about J. Geil, but as Devo would not talk, he destroyed the puppet, leading to Devo's death as well.

Trivia

 * It seems that Abdul and Devo had previously met, since he was able to give an accurate physical description of the killer. However he was unaware of Ebony Devil's powers, as he was not one of his victims and had only seen him from afar.
 * His name was changed in Viz Media's translation of the manga to avoid lawsuit from the band of the same name. He was instead named "Soul Sacrifice", a reference to the song of the same name by Santana.
 * In the game Heritage for the Future Devo can use his stand even after being de-aged by Alessi, implying he  was either born or developed his stand ability at a young age.
