Capitán Chance commands the specialized police unit Gorilla Force. Dr. Mundy of Garrick Prison deliberately recruited him for a covert mission requiring exceptional skills. Mundy tasked Chance with infiltrating Garrick Prison as an undercover prisoner to identify and recruit five specific inmates possessing unique talents: Babyface, Magician, Sexy, Superstar, and Jet. These individuals formed his elite team.

Chance's primary prison objective was orchestrating a meticulously planned escape with these recruits, serving as both their initial mission and capability test. Utilizing coordinated deception, including exploiting a staged musical performance by the kidnapped singer Presman Kingley and Sexy's distraction tactics involving a blinding crystal, Chance successfully united the team and breached the prison's maximum security. The escaped team rendezvoused with Magician at spatial coordinate S71 N25, solidifying the complete Gorilla Force unit under Chance's command.

Operating from a sophisticated spaceship concealed within a derelict exterior shell, Chance led Gorilla Force against the Organization of Evil, a powerful criminal syndicate threatening galactic civilization in Zone Subsqui. Volk Lazer led this organization, with Helgal as his chief enforcer. Chance functioned as the team's field commander and strategist, coordinating their specialized roles during missions. His leadership involved direct operational participation, urging his team forward in critical engagements like the intense battle to capture the merchant vessel *Reniera e Soderina*.
