The first squad leader of the Dark Axis invasion force. Zapper Zaku used to be an honest person. He fought fairly, cared about his friends, and believed that people become stronger by keeping promises. That was before Zapper Zaku became a squad leader. When Zapper Zaku was promoted, his personality became twisted. Now he prefers to shoot first then ask questions later, he never hesitates to threaten his subordinates, and fights dirty. Whenever Zapper Zaku leads an attack, he never has any sort of plan and just comes up with ideas on the fly. The only plan that Zapper Zaku came up with turned out to be the only plan of the Dark Axis trio that completely succeeded. Finally, Zapper Zaku is a skilled actor, able to fool enemies and allies alike with his acts.
