As Super-1, Kazuya Oki possesses 5 super-powered glove attachments called the Five Hands (ファイブハンド,Faibu Hando). To change arms, he does a circular motion with his hands and says "Change-(name of hand)".
Super Hands (スーパーハンド,Sūpā Hando): The default silver gloves that allow Super-1 to perform a super punch with a force of 300 tons.
Power Hands (パワーハンド,Pawā Hando): Red gloves that allow Super-1 to lift up to 50 tons of weight, as well as initiate the Megaton Punch (メガトンパンチ,Megaton Panchi).
Elek Hands (エレキハンド,Ereki Hando): Blue gloves that allow Super-1 to channel up to 10,000 volts of electricity, as well as fire the Elek Beam (エレキ光線,Ereki Kōsen).
Thermal Hands (冷熱ハンド,Reinetsu Hando): Green gloves that allow Super-1 to use the left glove as a cryogenic sprayer and the right one as a flamethrower.
Radar Hands (レーダーハンド,Rēdā Hando): Gold gloves that allow Super-1 to shoot missiles that emit radar waves, allowing him to see further from the radar screen on his gloves. The missiles can also be used as a projectile or modifed with explosives to strike an enemy target.
A heavily expanded evolution would later appear with the Heisei Rider, Fourze, an Astronaut Rider like Super-1, who uses Astroswitches to assume various Module attachments, with 10 of them being assigned to a single limb for a total of 40. Coincidentally, both Fourze and Super-1 are space-themed.
