Once during battle when he was surrounded by enemies trying to steal his mask, he used the Kinniku Clan's Niku Curtain to protect his mask and withstood their blows for 3 days straight until they collapsed. In the anime he uses the Kinniku Guard for 3 months to protect his mask during a Space Samurai invasion on Planet Kinniku.
However, as explained by his brother Nemesis in the Perfect Origin Arc, this story was a cover up meant to hide the fact that Tatsunori had to use the Niku Curtain to defend himself in a coup against him, led by the ministers from the last king's reign.
Furthermore, in Kinnikuman Nisei it is established that he created the Niku Curtain and founded the Royal Kinniku Family.
His name comes from Tatsunori Hara.
