The plot starts when 'Arnold' (a typical insurance company salaryman) encounters an alien named 'Alpha Man' from 'Planet Alpha'. The alien tells Arnold that an evil scientist named 'Dr. Bomb' is planning to set an "End the World" weapon. The alien then gives Arnold an odd metal rod, a fork and a coin, which turns him into Bravoman, a bionic tokusatsu hero who possesses telescopic limbs that can be used to fight against Dr. Bomb and his henchmen. Bravoman can mainly use his telescopic limbs to attack enemies. Depending on his position (jumping, crouching etc.) he will either use his arms, legs or head to attack.
