Devilman

Devilman is one of the demons of hell who are meant to destroy humanity. Arriving on Earth, he takes possession of the body of Akira Fudo, who was making an excursion with his father, after killing him. He will later be adopted by the Makimura, where he falls in love with Miki Makimura and renounces his old purposes by deciding to save mankind and betray the demons. Despite her new purpose, she will continue to despise humans, behaving aggressively with everyone except Miki. Each time he transforms into Devilman he radically changes his appearance, increasing the size of his body which takes on a green color and with the appearance of red wings on his back.
