Kinnikuman

Status: Releasing
Genres: Action , Comedy , Sports

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".

Notes:

Kinnikuman won the 30th Shogakukan Manga Award for best children's manga in 1984.

Tiger Mask

Also known as Tiger Mask.

Status: Finished
Genres: Action , Sports

In the manga and anime, Tiger Mask (whose real name was Naoto Date) was a feared heel wrestler in America who was extremely vicious in the ring. However, he became a face after returning to Japan when a young boy said that he wanted to be a villain like Tiger Mask when he grew up. The boy resided in an orphanage, the same one that Tiger Mask grew up in during his childhood. Feeling that he did not want the boy to idolize a villain, Tiger was inspired to be a heroic wrestler.
The main antagonists in the manga and anime was Tiger's Cave, a mysterious organization that trained young people to be villainous heel wrestlers on the condition that they gave half of their earnings to the organization. Tiger Mask was once a member of Tiger's Cave but no longer wanted anything to do with them, instead donating his money to the orphanage. This infuriated the leader of the organization and he sent numerous assassins, including other professional wrestlers, to punish him.
Most of the environment and characters were fictitious, but real-life pro wrestlers Antonio Inoki and Giant Baba were included in the manga and anime as well.
