### Transformation

Following the surgery by fellow Shocker Scientists which replaced his arm, Ace was able to transform into Riderman. While a belt was part of his Riderman Suit, it is not the source of his transformation unlike the first three Kamen Riders and indeed the majority of those that would follow. Instead, Ace Runner transforms by raising his hands in the air, with his helmet materializing in his hands. He then puts the helmet on and then his gloves, belt, and the suit itself appears over him.

### Cassette Arms (or Attachment Arms)

*Main article: Cassette Arms*
What Riderman lacked in physical strength of the Extra Riders, as well as most of the Riders before and after him, he made up for in persistence, smarts, and his wide array of prosthetic weapons to meet his needs. His weapons were also the basis for the "Rider Slash" and "Rider Shooting" finishing attacks.
