Go-Gadoru-Ba

Go-Gadoru-Ba appeared in 2000 TV series called Kamen Rider Kuuga. Go-Gadoru-Ba (ゴ･ガドル･バ Go Gadoru Ba), known to the police as Unidentified Life Form #46 (未確認生命体第４６号Mikakunin Seimeitai Dai Yonjūrokugō) and B11 (Ｂ群１１号 Bīgun Jūichigō) is one of the strongest Gurongi Kuuga had ever faced.

Armed with various weapons similar to Kuuga, Gadoru assumes the form of a man in militant garb. As the Go's leader, he intervenes in the fight between Zazaru and Gooma and later comes to Baruba's aid against a power-mad Gooma when Kuuga arrives to witness him putting the bat Gurongi back in his place.

With Daguva going to Tokyo soon, he and the other two remaining Go undergo the same process as Gooma to ready themselves. After his two allies were killed, Gadoru is the last of the Gurongi to play. After undergoing training to ready himself, Gadoru heads to the police department to find worthy opponents to fight as part of his game.

When confronted by Kuuga in his default Grapple Form (格闘体Kakutōtai), Gadoru reveals his new ability to the different powers of Kuuga, assuming Quick Form (俊敏体 Shunbintai), Shooting Form (射撃体 Shagekitai), and Herculean Form (剛力体Gōrikitai), before defeating Kuuga at full-power in Shocker Form(電撃体 Dengekitai). But due to Ichijo, Gadoru's game had to be reset as the Gurongi attempts to kill Dorudo for failing his part.

After Dorudo retreats, Gadoru attempts to kill Ichijo upon being wounded by the officer's Nerve-Breaking Bullets as Yusuke arrives to battle the Gurongi as Kuuga. Once taking their fight to the woods, Kuuga assumes Amazing Mighty Form and destroys Shocker Form Gadoru.

Go-Gadoru-Ba, among many other revived monsters, was part of the Dai-Shocker army in the World of Decade that was fought and wiped out by a gathering of 25 Kamen Riders.
