Personality
Despite being built for evil, Luffy Bomber prefers to do things his own way and does not seem to obey Usodabada, as such his intentions are usually a riddle, but he is a genuinely friendly robot who doesn't mind helping others. He does not appear to be too bright but always knows what must be done, although this can make him quite impulsive. He is fearless and fights with everything he has without hesitation. Despite being a robot, he has a great love of meat and eats gigantic portions of it whenever he can. He is also a heavy sleeper, and may fall asleep during improper moments or at improper places. Due to his friendly nature, he became fast friends with Chopper Man upon their first meeting.
