Leonero was a member of the Spade Pirates. After Whitebeard defeated the gang, the entire crew was taken over by him.
- His name was first announced in One Piece magazine for the manga series’ 20th anniversary.
- Like all other former members of the Spade Pirates, with the exception of Ace, Leonero has only appeared in flashbacks in the manga. Thus, he did not appear during the Battle of Marineford.
