Luffy has a worldwide reputation for causing trouble, challenging the Shichibukai, the Marines, and even a Yonko, additionally committing felonies and actions which were deemed threatening by the World Government. Furthermore, in the majority of these confrontations, he emerges as the victor. He has gained a reputation for being "reckless" and, in some cases, "insane", after causing an incident in Enies Lobby, assaulting a World Noble at Sabaody Archipelago, entering and escaping from Impel Down, and joining the Battle of Marineford.
