S1·E29 The Continent of Sakezan

Sakezan is the only human living in a jungle world named after him. He is a parody of Tarzan and, as his name suggests, is very fond of saké. Sakezan captured Maetel when the 999 took a quick stop there and she became her slave/companion. In an attempt to rescue her, Tetsuro was defeated by Sakezan and ended up in a prison cell.
