* FriendVersusLover: With whom I played. While he is not as openly envious of Miki's friendship with Akira as his Manga counterpart, he has shades of it. Miki's actions were justified owing to [[spoiler:him being a PoisonousFriend. However, we only see her in this posture when Ryo makes an appearance.]]to:
Satan is the primary enemy of the Devilman manga and anime by Go Nagai. He is the fallen angel, expelled from Paradise for defying God, and has assumed leadership of the demonic people, shielding him from God's messengers and leading him in the battle against God and the angels. He wants to eliminate humanity in the boy, who blames himself of destroying the planet Earth, converting it from a fruitful and uncontaminated world into a polluted world, but at the same time he falls in love with one of the humans: the kid Akira Fudo. As a result, I take human form and disguise myself as Ryo Asuka, professing to be a friend of Akira and sacrifice Amon, his most powerful soldier, to challenge Akira to live after the annihilation of humanity. Compare to Ryo Asuka in the first chapter of the manga, but its actual form is revealed only in the last chapter. Compare the manga Devil Lady, Demon Knight, Amon - The Darkside of Devilman, and Strange Days.
As Satan was reborn as a youngster called Ryo in the Amazon, he was adored by a local tribe. As the tribe was assaulted by troops, he was granted heavenly protection and floated on the water until he reached the shore of Japan, where he was struck unconscious and discovered by Akira. Despite their friendship, Ryo was later adopted by a demon dubbed Psycho Jenny, who disguised herself as a secretary while he was a professor. As Satan explains, the reason he permitted Amon to merge with Akira was so that Akira would be powerful enough to dwell in the new world with him, a world where mankind has become extinct. Akira becomes enraged and breaks up their relationship, refusing to fight.
Satan had rebelled against God's harsh and terrible authority, and was subsequently exiled to Earth during its ancient period. There, he discovered the demons, who he found fascinating in their simple yet harsh ways. Satan and the demons, on the other hand, would prosper if God's army attacked Earth to wipe out the devils and start again. In the case of Satan, he would reincarnate. Satan was born as a weirdly skinned and haired kid into a Peruvian primitive hamlet. As his abilities were apparent, he started to be worshiped as a deity, to the point of sacrifice and heart offering. One day, a military detachment raided the settlement, and Satan was thrown into the sea. He ended himself drifting and washing up on a wharf in a Japanese hamlet, where he met the young Akira.
