Magia

Magia are HumaGears that have been hacked to turn into twisted monsters and major antagonists in Kamen Rider Zero-One.

A Magia is created when a Zetsume Riser produced by MetsubouJinrai.NET is attached onto a HumaGear. The HumaGear then inserts a ZetsumeRise Key into the Riser, causing their skin to burst off and reveal their metal skeleton before tendrils burst out of their mouth and wrap around the body, remolding it into a mechanical monster.
