Dragonball Z: The Elemental Lords
Former lieutenant of Lord Caius, Void was replaced by Sem after he attempted to overthrow Lord Caius (and nearly succeeded). The fight between Void and Lord Caius lasted for days, Maru had already been nearly killed and all of the captains who were still alive were too scared to join in the fight. Until the massively powerful captain, Sem, fought past his fear and threw himself at Void, providing enough of a distraction for lord Caius to gain the upper hand in the battle. Void was eventually overpowered and placed into a chamber that suppressed his powers and restrained him. This chamber was then placed in a maximum security facility where he was kept for decades, until he was brought to earth by Eurhel as an ironic means to defeat those standing in the way of returning Lord Caius to power.
Now abandoned on earth he searches for means to return to Churak and exact revenge upon his former captors.
