Gryphus

Gryphus was a son of Zeus. He was more handsome than Adonis and a natural leader. When he began to lead people away from the worship of the Olympians and killed those who opposed him, Zeus punished him by turning him into a Minotaur and imprisoning him in a Labyrinth in Alturia. Gryphus remained imprisoned for one hundred years until Andius and Danion accidentally set him free. Gryphus was bent on revenge and in order to hurt Zeus he targeted Hercules.Gryphus was briefly visited by Zeus who states that Gryphus still hasn't learned his lesson to which the Minotaur replies that Zeus doesn't have the heart to kill him. Hercules had to go into Gryphus' lair in order to kill him. They began fighting and as Hercules was about to kill the Minotaur, the creature revealed that he was really Hercules' brother and Hercules could not kill him. When Gryphus lunged toward Hercules, he ended up throwing Gryphus onto a stalagmite which impaled him. As he was dying, Zeus appeared and stated to Hercules that Gryphus was dead the day he started leading the people away from worshipping the Olympians. When Gryphus asks for Zeus not to let him die like this, Zeus transformed him back into his mortal appearance as Gryphus died and his body disappeared in the fog
