Captain UFO is an arrogant and astute criminal mastermind, he was among the four members (along with General Sahara, Hell Boxer and Baron Iron Mask) of the Big Four lead by Iron Claw.


He was the captain of the UFO command ship that the Crime Big Four used to travel the world.

Facing the JAKQ and Gorenger teams, Hell Boxer and the rest of the big four combine into the super cyborg entity “Big Four Robo”, a monstrous and hulking mechanical monster with multiple cannons protruding throughout his body and a grinder in his lower torso. Virtually invincible, it took the combined special attacks of JAKQ's Big Bomber and Goranger's Goranger Hurricane Ball to destroy the monster.
