One Piece: Crocodile

From the start, he transmigrated into the world of the Pirate King, and even took over the body of Crocodile, one of the Shichibukai. Unfortunately, the timing of his transmigration was terrible! He arrived just as Crocodile was being sent to Impel Down! Without a System, Crocodile had no idea how to break out, so all he could do was wait for Luffy to come rescue him! After getting out, he joined the Paramount War. By changing history, Crocodile gained enormous benefits from the battle. Luffy: Crocodile actually helped me! Whitebeard: You lousy little crocodile brat, I can't believe I owe you one! Sengoku: You bastard, Crocodile! Doflamingo: Crocodile, not only did you make me jealous, you even want to take over my Dressrosa!
