Chico Biente is a teenage member of the Deloyer 7, the primary rebel group fighting for Deloyer's independence. He fulfills the vital role of weaponeer, specializing in heavy armaments. His signature weapon is the powerful portable laser cannon, the Big E-Gun, capable of piercing weak points in enemy Combat Armors with a single shot – a critical asset for the rebels' guerrilla tactics against the Earth Federation's mechanized forces.

Operating alongside core members like founder Rocky Andrew, second-in-command Canary Donetto, and Dougram pilot Crinn Cashim, Chico battles across Deloyer against overwhelming odds. His combat role typically involves providing essential fire support, frequently partnering with Canary in auxiliary actions during engagements.
