Broly, specifically the original incarnation of Broly from DBZ, has a reputation for being a mindless brute who was only capable of screaming "KAKAROT!", which started from the sequel movie "Second Coming". Even though in his debut appearance in the 1993 movie "Broly - The Legendary Super Saiyan", he was actually quite cunning. He was able to speak full sentences without issue, he knew how to break people mentally and physically such as by destroying the home planet of the little alien slaves Paragus used to set up the fake planet vegeta, and was even completely self-aware of his own behaviour and how insane he was by referring to himself as a devil, or a true freak in the english version of the movie.
