Watch Kinnikuman Nisei (Dub) - Episode 69

Kid Muscle (or Mantaro for short) is a bumbling, gross, and wimpy sort-of person. Unfortunately, he has been summoned to protect the earth from the evil dMp, a band of cheating wrestlers from outer space. Luckily he's not undertaking this task alone. Kid Muscle must join the Muscle League, a group of wrestlers from outer space who are training themselves so they can defend the earth, and stop the dMp by achieving "Ultimate Muscle", a hidden power that makes Mantaro an almost unbeatable opponent.
