―Transformation phrase as Bikaiser.[src]

Kaisei Mogami (最上魁星 Mogami Kaisei) was the counterpart of Kaisei Mogami in the World of Ex-Aid.

Character History

As Kaiser Reverse, this Kaisei Mogami made his appearance before the Gamer Riders at Seito University Hospital. Taking claim for the Nebula Bugsters unleashed there. Following his counterpart in the World of Build, Mogami activated the World of Ex-Aid's Enigma device, causing the Gamer Riders' transformations to be cancelled and rendering them defenseless. Kaiser Reverse attempted to kill the doctors only to be met by Kamen Rider Ghost, who assumed Newton Damashii to defeat the Nebula Bugsters accompanying him. Seeing his advantage lost, Kaiser Reverse took his leave. Kamen Rider Heisei Generations FINAL: Build & Ex-Aid with Legend Riders


Post-mortem

Sento was reminded of the unification of the two Kaisei Mogamis into Bikaiser when he witnessed Fu Washio transform into Hell Bros. The Counterattack Hero

Personality

This counterpart of Kaisei Mogami is louder and more ruthless, and is more focused on the annihilation of the Kamen Riders than the humans.
