Luffy has a worldwide reputation for causing trouble, challenging the Shichibukai, the Marines, and two of the Yonko (Big Mom and Kaido), 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.
