In some rare cases, a Kamen Rider is part of the same species/organization that the antagonists are from. These Kamen Riders all possess monster forms separate from their Rider powers and equipment and their affiliation can be either good or evil.
In a few minor cases, the form in question is only temporary and they can have their humanity restored or at the very least regain control of their human nature and transform back into their original persona again.

Notes[]
- Technically, some of the Riders' basic forms are a monster form.
- Double Riders: Grasshopper Man (Shocker)
- Kamen Rider Stronger: Electric Human Stronger (Black Satan)
- Kamen Rider ZX: Perfect Cyborg (Badan Empire)
- Kamen Rider Shin: Cyborg Soldier Level 3 (Institute of Super Science)
- Another Riders
- Additionally, the original Kamen Rider Amazon has been noted to have a monstrous appearance. This is acknowledged in-universe by Yusuke Onodera's remark that the A.R. Amazon appears more like a monster than a Rider in episode 28 of Kamen Rider Decade.
