Ra-Dorudo-Gu

Ra-Dorudo-Gu appeared in 2000 TV series called Kamen Rider Kuuga. Ra-Dorudo-Gu (ラ･ドルド･グ Ra Dorudo Gu) is a condor-like Gurongi armed with a pair of tonfa, Dorudo assumed the form of a man in black with white robes on him, and is labelled by the police as Unidentified Life Form #47 (未確認生命体第４７号 Mikakunin Seimeitai Dai Yonjūnanagō) and B#9 (Ｂ群９号 Bīgun Kyūgō).

He carries an abacus which he uses to count the number of kills by the Go Group Gurongi until Ichijo destroyed it with a Marking Bullet, forcing the Gurongi to reveal his true form in a hit and run attempt to kill Ichijo.

However, as a result, Dorudo lost his purpose as the game's overseer and is forced to fight for his life against Gadoru as Ichijo arrives to the scene.

Dorudo eventually attempts to retreat from the fight and is pursued by Sugita and Sakurai who shoot him dead with the completed Nerve-Breaking Bullets.

In the World of Kuuga, he is labeled Unidentified Life Form #8 (未確認生命体八号 Mikakunin Seimeitai Hachigō). He fights Kuuga and attempts to flee before being destroyed by Kuuga who uses Pegasus Form's Blast Pegasus attack.

At least two Ra-Dorudo-Gus were part of a group of human-turned Gurongi created when they were exposed to N-Gamio-Zeda's miasma. Some were later absorbed by him in a last effort to defeat Kuuga and Decade. The remaining Gurongi died after Gamio was defeated.
