Part in Story

Watcherman appears throughout the series as the aforementioned informant. He owns a Futo-kun Bicycle that he won in a mail-in contest. Akiko used the bike to chase after a garbage truck that had a doll that belonged to the Puppeteer Dopant.

In Kamen Rider W Forever: A to Z/The Gaia Memories of Fate, Watcherman finds the T2 Violence Gaia Memory, which forces him to become the T2 Violence Dopant. He is freed after Kamen Rider Double LunaJoker used the Joker Strange on him and Santa-chan as the Ice Age Dopant. He and Santa-chan explain what happened and end up in a free clinic where they stay during NEVER's attack.

It is presumable that he still helped the Narumi Detective Agency after W`s series ended.

Watcherman was contacted by Shotaro to investigate the mysterious witch his client was looking for, at first having no leads. However, he later contacted Shotaro about rumors and reports online of "The Witch of the T Junction", a beautiful thief who steals women's clothes and robs men of their money. Shotaro thanks him and pays Watcherman for his information, only for the two of them to see the fabled witch in front of them. Shotaro tells Watcheman to run to safety, but the excited otaku tries to take a photo of her with his phone only for Shotaro to accidentally knock it out of his hand and break it while chasing after the witch.Be Wary of the T/The Man who fell in Love with a Witch

Dopant Form

  • Height = 230cm
  • Weight = 420kg

As the brutish Violence Dopant (バイオレンス・ドーパント Baiorensu Dōpanto), his left arm is strong enough to destroy anything in its path, even enough to smash through cars. He can compress his body into a wrecking ball-like form called the Violence Ball (バイオレンスボール Baiorensu Bōru) to cause more collateral damage.

  • His bike, Fuuto-kun' was won in a sweepstakes. This is a nod to the actor appearing in Susunu Denpa Shonen where he was locked in a room until he won 1,000,000 yen worth of prizes from postcard sweepstakes.
