Giant Gamma

A Giant Gamma (巨大眼魔) is a form which can be accessed when an evolved Ganma absorbs a Parka Ghost before a Kamen Rider catches it in a Ghost Eyecon, causing them to change 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 Gamma to separate both the stronger Gamma and the Parka Ghost that the monster has absorbed. The Iguana Ghostriker is most useful at dealing with Giant Ganma.

Giant Ganma

 * The Denki Ganma became giant when it absorbed the Edison Parka Ghost. It was defeated by the Iguana Ghostriker, reverting it back to its humanoid form as the Edison Parka Ghost was released.
