Brolly makes his appearance in movie 8, when the z team goes to the new planet Vegeta. Brolly, who is controlled by some collar thing, fights the Z team. He is controlled by another guy(sorry, I can't remember the guy's name right now) but breaks the collar, and thus fights the Z team without limit. Goku defeats him, but he returns in movie 10. He fights the team once more and loses. THEN, he appears AGAIN in movie 11, by this time you're thinking: Dammit, kill this guy and get it overwith. His charecter runs stale quickly because of this, but he is finally killed in this movie.
