Kinnikuman (a.k.a. Kinniku Suguru) is a cowardly, clumsy, moronic, gyuudon-devouring excuse for a superhero (or Choujin)... who just happens to be the prince of an alien planet. But despite his pathetic appearance, he is very honorable and can become quite powerful when he needs to be. With his sidekick Meat-kun and fellow Choujins Terryman and Ramenman there to help him, Suguru quests to become the greatest Choujin on the planet. Whether with a combination of tremendous heart and stamina (The Burning Inner Strength) or the "Power of Friendship", Kinnikuman frequently defeats villians 10 times more powerful than him and often causes his enemies to have a change of heart and join him. Though he seems destined to be an idiot forever, slowly but surely Kinnikuman becomes worthy of the title "Hero".
