Born to Mayumi and Sayuri Kinniku, the king and queen of Planet Kinniku on April 1, 1960. Suguru was so stupid looking, even as a child, that on several occasions Mayumi would have an urge to strangle him just from looking at him. On one fateful day, The royal family went on vacation to Earth. While there, a pig snuck on board and got in Suguru's cradle. Mayumi mistook Suguru for the pig and threw him out of the ship. Suguru was left behind on Earth to raise himself. He built his own house and tried to go to school, but he was so stupid that he flunked out of school and his house had only one room. As he got older, he decided to become a hero like Ultraman. But despite his muscles and strength, he was too clumsy and stupid to make it, so he settled for just being the president of the Gyuudon Lovers Club.
Without his "burning inner strength" or "fire" which helped him evolve and become stronger in each battle he took (because of that power five evil gods feared him), he has other secret powers, like when he takes off his mask he releases some healing or purification powers, flight, and turning into a giant. This is probably why members of the Kinniku royal family must not show their real face and must always wear masks. In manga chapter 326 is revealed that power is called "Face flash" which possess Kinniku clan members.
