Empowered Gamma

Gamma Assault (眼魔アサルト) are the unique evolved forms which are accessed by the Ganma to grant them greater power. They achieve this through the Ganma Eyecons which they are born from, when the Eyecon bonds with an object in the physical world the object is then converted into their equivalent of a Parka Ghost which they infuse with their Primal Body, completing the transformation.

If a Ganma Assault should absorb a heroic Parka Ghost before a Kamen Rider catches it in a Ghost Eyecon it will become a Giant Ganma, changing into a bigger and more powerful form based on their unique motifs. In order for Kamen Rider Ghost to free the Parka Ghost and capture it in an Eyecon, he must first defeat the Giant Ganma to separate both the Ganma Assault and the Parka Ghost that the monster has absorbed.

Upon being defeated by a Kamen Rider, the Ganma Assault is forcibly returned to its Primal Body before it is subsequently destroyed alongside its Ganma Eyecon and Parka Ghost which returns to the object it had bonded with.
