It’s not like I’m wanted.”Ike: “Huh? We’re a Private Marine crew. We just fly the Jolly Roger, but we’re not pirates. Why would we be wanted? One call, and the bounty is gone.”Crocodile: “The Straw Hats are in Alabasta. Why isn’t the Marine arresting them?”Marine officials: “Huh? They’re Private Marines, not pirates.”World Government: “The Straw Hat Pirates destroyed Enies Lobby! Arrest them immediately!”Ike: “Who said that?
