Kinniku Tatsunori was a great fighter of the Kinniku Clan and the father of Kinniku Mayumi, as well as the brother of Sadaharu Kinniku. He appears in a series of flashbacks throughout the series, but plays a more prominent role in Kinnikuman (2011). The KIN Mark is on his forehead.

Mayumi Kinniku tells a story to Kinnikuman during the finals of the 21st Choujin Olympics: The Big Fight, where he describes how Tatsunori Kinniku was a great warrior. During one war, he was almost captured and those that captured him sought to remove his mask, but - in an act of self-defence - he used a technique called the Niku Curtain. He was punched and kicked for several days straight, but he never once lowered his arms or let down his guard. Eventually, the enemy gave up and he was able to preserve his mask.

In the anime he uses the Kinniku Guard for 3 months to protect his mask during a Space Samurai invasion on Planet Kinniku.
