Cameo

Cameo is a minor antagonist featured in Part III: Stardust Crusaders.

Personality
Cameo is a coward man who likes to toy with people's hearts. He is not afraid of turning people's wishes against them and make them suffer. His attack consists in acting as a humble servant of his enemies, only to turn against his "master" without mercy after showing his true intentions, protected by the thought that the enemy will not attack his relatives (actually clones created by the stand Judgement). He often shouts "Hail 2U!", after granting a wish, and as a battle cry

Stardust Crusaders
Cameo is one of the mercenaries hired by Dio Brando to kill Jotaro and his party, waiting on the island where Joseph is visiting Avdol's father. Cameo spends the entire time underwater, inside a hole dug by himself, wearing swimming goggles and a breathing straw. With the lack of damage connection between him and his stand, Cameo allows the automatic stand to do all the work while he watched closely. He uses his stand Judgement to make Polnareff believe it to be a genie and express his three wishes. Polnareff asks it to revive Sherry Polnareff and Mohammed Avdol, and so Cameo creates clones of them who end up attacking Polnareff. The real Avdol shows up and saves Polnareff from the clones, destroying them and finding Cameo's hideout. Much more easy-going than before his "death", Avdol suggests to Polnareff that they should torture him a little, blocking his breathing straw with his finger for a few seconds and laughing, all the while Cameo suffers with the lack of air. The pair end up urinating into his breathing straw, which prompts to a terrified Cameo reveal himself and beg for forgiveness. Avdol refuses and uses Magician's Red to burn him as his fourth and last wish.
