Osiris is a humanoid Stand; with large, muscular arms marked by lines of a vascular pattern; of a thick brow, and fingers capped by suckers. It is only revealed from the chest up; mist obscuring a possible lower half.
It doesn't show any personality and follow Daniel's instruction mindlessly.
According to JOJOVELLER, its appearance is a rearranged African traditional picture, with mechanical parts.
Osiris represents the Egyptian God Osiris; related to prosperity and life after death.
Osiris is an Automated Stand that completes Daniel J. D'Arby's gambling and cheating skills. More precisely, it is the cooperation of Daniel's gambling and Osiris' ability to steal souls on easy-to-reach conditions that make the pair so dangerous. Because of this, Daniel nearly defeated the entirety of the Joestar Group.
Soul Removal: Osiris has the ability to take the soul of anyone who loses against D'Arby be it in a bet or in a game.
More specifically, it will act when the opponent "admits defeat in their heart", which is said to reduce their soul energy to near-zero. However, D'Arby needs his opponent to agree to gambling their soul. If the loser bets the soul of another person, Osiris can take it even if that person is not present or agrees with it. Cheating is allowed when gambling against D'Arby, who he himself considers perfectly acceptable, as long as you don't get caught.
The souls are compressed by Osiris' fists and stored in a semblance of poker chips, which D'Arby keeps as a collection. D'Arby is then free to gamble individual souls or even split a chips in several blank pieces to used in a game, with all of the parts being equal to one soul. If he recognizes defeat, the souls he's gambled are released. He can also release the souls at will if he wants.
According to Daniel, if he dies, so does the people from whom he took the souls.
