Vincent Volaju is the main antagonist of the Cowboy Bebop movie, Knocking on Heaven's Door. He is a terrorist who planned on unleashing a virus on all of Mars on the night of Halloween.
He is voiced by Tsutomu Isobe in the Japanese version and Daran Norris in the English version, the latter of whom also voices Nakago.
Vincent first appears detonating a medical truck and unleashing a nanomachine virus. Faye Valentine catches a glimpse of him while looking for a bounty head who was supposed to be driving the truck. In an episode of Big Shot, an award 300 million Woolongs is put on Vincent for the attack. When Spike spots Vincent outside a Pharmaceutical building, he chases him towards a train station. After a brief fight, Spike knocks him down, but Vincent grabs Spike's chest and twists it, then shoots him out of the train before detonating a grenade that destroys the train. Later, he is planning to initiate his terrorist attack on the Halloween parade, so Faye hijacks the weather control system for Mars to start raining. Spike finds him at the top of the tower and the two engage in a long and brutal fistfight until Electra arrives and shoots him, and as Vincent dies remembers her and admit that she was the one he used to love.
