Ogun Bat is a Japanese superhero created by Takeo Nagamatsu in 1931 and is considered to be the first Japanese superhero. The anime ran 52 episodes between April 1st 1967 and March 23rd 1968.
In Ogun Bat, Professor Yamatone and his family visit present day Egypt, and discover an ancient tomb belonging to a god of justice, who is also a protector of the weak.
When the Professor is taken captive later by Gorgo, agent of the evil Dr. Erich Nazō, his daughter Mari pleads for the god of justice to save her father. As she starts to cry, her tears fall into the ancient tomb, reviving Ogon Bat, who comes to her aid.
From then on, the little girl calls on the Ogon Bat to fight against evil – usually in the form of Doctor Zero!
