Beast King GoLion was created in 1981.
Not intentionally. However, the similarities are obvious when you think about it. Ialdabaoth challenged his mother, the goddess Sophia, by saying that he was the only god in all of Creation. She responded (in one story) by revealing the true majesty of the unknowable God unto him and then casting him into the Abyss. In GoLion, the robot GoLion channenges the Goddess of the Universe and she responds by chastising him and then casting him into space... splitting him into five lions in the process. Both Ialdabaoth and GoLion were lion deities. In fact, GoLion is actually enshrined as the guardian deity of a whole planet at the end of the GoLion anime series. And Sophia would actually be the Goddess of the Universe from a Gnostic point of view. Maybe the Japanese enjoy putting in little nods to western religions in some of their anime? In the manga Peacock King there was even something to do with the Holy Grail being the skull of Jesus. So you never know. It is entirely possible.
