Raizou Shioka

Shiokara is the oldest leader of the Roborobo Gang (Rubberobo Gang in the dubbed version), playing the role of the team's "muscle". The polar opposite of Sarami, he has trouble with kids, and is a firm believer in senior superiority. Called upon whenever brute force is required, Shiokara is sadly good for little else, being infamous for his stupidity, even among the scatterbrained legions of the Roborobo Gang.
