Biography
An A.R. version of Alternative is an evil Rider associated with the Dark Riders who assumed the guise of the Negatives World counterpart of the real Tanaka, Natsumi Hikari's high school teacher. Though ordered by Otoya Kurenai (A.R. World) to keep an eye on Natsumi rather than kill her, he intentionally decides to attack Natsumi, resulting in Dark Kiva beating him merciless. Alternative is then later destroyed by Kamen Rider DiEnd.

Contract Monster


The Alternative's sole contract monster, Psycorogue, resembling a humanoid cricket, had the ability to transform into a motorcycle named Psycoroader through the use of the Wheel Vent Advent Card and during the Alternatives' Final Vent Dead End. This Mirror Monster had an opposite color scheme to its corresponding Rider, having white armor with black accents. Its name is a portmanteau of the two words, psycho and koorogi, which is Japanese for "cricket".
