Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Rider
Following Zaizen's downfall, the alias of "Dr. Pac-Man" would be taken by Parad as he interrupted Kuroto Dan's own plot to utilize the Ganbarizing Gashat as part of a game in which he provided Bandai Namco-based Gashats to the doctor Kamen Riders.
Admitting to Taiga Hanaya that Emu Hojo was patient zero of the Game Disease, Kuroto Dan claimed that he was given it six years ago in an experiment conducted by Michihiko Zaizen. He neglected to mention, however, that it was he himself who first gave him the Bugster Virus a further decade prior. Dan would later confess to Emu that he had ordered Zaizen to extract the matured virus from him. The said virus is also revealed to be Parad.
