* CompleteMonster: [[AGodAmI Kaisei Mogami]] is a MadScientist with an InferioritySuperiorityComplex. Believing himself to be smarter than his former partner, Takumi Katsuragi, Mogami began working for Juzaburo Namba and [[Film/KamenRiderHeiseiGenerationsFinalBuildAndExAidWithLegendRiders teamed up]] with his alternate self, a Foundation X researcher. Creating the Enigma, Mogami intended to use his machine to merge the two worlds and collide them with each other, leaving only him alive as an omnipotent being, the Bikaiser. Using innocent civilians as batteries by infecting them with Nebula Bugsters, Mogami revives the [[Series/KamenRiderFourze Horoscopes]] and the [[Series/KamenRiderOOO Greeed]] to distract the Riders, ordering Ankh to attack Eiji, fully knowing that he was his best friend, while continuously mocking the Riders with the information that they could watch the destruction of their worlds.
