Jyangyaru's Pursuit (JYANGYARU no Tsuiseki- ジャングルの追跡) - S1.E32

Jangal did a test on his robot in Popolonesia islands but unfortunately for him, his activities were sighted and reported to the Voltes team. Voltes attacked the robot and Jangal's flying saucer and made it crashed on an island. Jangal escaped into the jungle and the Voltes team were after him. Ippei wanted to kill him but Kenichi wouldn't let him. Kenichi said that he had Boazanian blood too, so Jangal was his fellow man.
