Weretiger

The Weretiger (voiced by Kingoro Torajima) is a Phantom born from a man called Igawa (井川) when he gave up in despair. Igawa described himself as a "muscular man" (筋肉質な男 Kinniku Shitsu na Otoko), who seems to be focused on strength training but is even stronger in his true form. In addition to his sheer strength he was equipped with a sword and launch energy balls from his pectorals.

Weretiger is ordered by Medusa to go after the Gate Toshie Nitoh (仁藤 敏江, Nitō Toshie), Kosuke Nitoh's no-nonsense grandmother who came to Tokyo to take Kosuke back to their home in the Fukui Prefecture.

With aid from Gremlin, posing as a bus driver, Weretiger reveals Kosuke's identity as Kamen Rider Beast to Toshie as she willingly offers herself as a sacrifice to nourish her grandson.

Just as the trade of the captured Shunpei for Toshie take place, Weretiger tries to push Toshie into despair by killing her grandson, but Haruto intervenes and he and Kosuke fight Weretiger and Gremlin, with the latter getting his Beast Driver back.

After Kamen Rider Wizard handles with Weretiger via the use of the Drago Timer, he lets Kamen Rider Beast finish him off with his Strike Beast Rider Kick.
