Wild Joe is one of the main antagonists of Oda's one-shot Wanted!. He is killed early in the story and is a ghost for the rest of it.
In One Piece, Joe's wanted poster can be seen among others in Fullbody's ship, at the Gold Roger Bar in Loguetown, and at the beginning of One Piece Movie 9. His bounty is 2,000,000. His wanted poster can also be seen in Whiskey Peak in the anime, when Zoro and Luffy were fighting and Vivi rode into the middle of the fight. Once the situation calms down, the wanted poster can be seen.
