Incinerator (Movie Voyager)
"Since the end of the war and the destruction of MEGATRON, more and more individual DECEPTICONS have been appearing on Earth chasing rumors that their leader still lives. Most choose to remain hidden from the AUTOBOTS who have stayed behind to defend the world, but not INCINERATOR. He's actively hunting AllSpark enhanced AUTOBOTS, reasoning that one of them must know where MEGATRON is. When he catches an AUTOBOT, INCINERATOR takes him on a little ride, swooping and diving dangerously, hovering over canyons and volcanoes, and generally terrifying whatever information he can out of his victim. When he's done, he just finds the deepest hole he can and drops his helpless prey in."
