Shioka, Raizou

Raizou Shioka (Shiokara) is the eldest of the four commanders of the Roborobo Gang (known as the Rubberobo Gang in the dub), serving as the team's designated "muscle." Unlike Sarami, he has difficulty interacting with children and firmly believes in the superiority of his elders.
Frequently called upon when brute force is needed, Shiokara is capable in combat but little else, as he is widely considered extremely dim-witted—even by the already chaotic standards of the Roborobo Gang.
