The character was created by writer Ichiro Suzuki and illustrator Takeo Nagamatsu in 1930. Ougon Bat made his debut in Kamishibai, a traveling show in which a sequence of pictures is narrated by a storyteller and was very famous before World War II.
In these early stories Ougon Bat was a superhero that had a golden skull shaped head, a green and white 17th century costume with a high collared red cape and was armed with a rapier sword. He possessed superhuman strength and invulnerability as well as the ability to fly. He also lived in a fortress in the Japanese Alps.
In the TV anime and the live action films from the 60s the character was a “God of justice and protector of the weak” from the ancient and legendary lost city of Atlantis who was put into suspended animation in a sarcophagus to be awakened in the future to fight the forces of evil. In the anime the character still has a golden skull head and the red cape, but now has a golden armored bodysuit and is armed with a staff.
In the cancelled late 90s remake the character was re-imagined with a new skinnier and more gruesome look with vampire fangs in the golden skull as well as having the ability to fly with bat wings instead of the original Superman-styled flight. The powers of Ougon Bat also were upgraded and he now has the ability to perform several powerful energy attacks.
