==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's Dimension Blast.

====Neverending Story====
Alternative wasn't Amadum's monster (only used as a Dark Rider) in the world within the Magic Stone. With the Batta Yummy and Arch Orphnoch, they attacked and defeated Beast when he intruded in Amadum's lair as he planned to harness the Kamen Riders power, forcing Beast to his proper place in space and time. The three monsters later appeared to capture the young Haruto and Koyomi, fighting off Haruto, Rinko, and Shunpei, when they tried to stop them. They brought the children to Amadum as Tsukasa Kadoya gave him the thirteenth and last Rider Ring (Fourze). The Kamen Riders refused to fight Haruto, saying they fought for human freedom and not just justice, engaging Amadum's monsters. Alternative, Batta Yummy and Arch Orphnoch, along with several other monsters, were destroyed by Wizard and Decade.
