Satan (Ryo Asuka)

Satan, also known as Ryo Asuka, is the main antagonist of the Devilman franchise, He serves as the archenemy of both his best friend Akira Fudo and Amon. Once an angel who rebelled with the Demons against God in the ancient past, Satan created the false persona Ryo Asuka and tricked Amon into Akira's body for their own desires. They appear in the form of a twelve-winged angel. Ryo is a good friend from Akira Fudo's past. His father had killed himself after becoming possessed by a demon and left Ryo with a terrible legacy. Ryo saves Akira and Miki Makimura from bullies by pulling a gun on them. He takes Akira to his place and shows him what the world was like back when demons ruled the earth. After an attack by several demons, Ryo tells Akira that the only way to beat a demon is to be a demon. Ryo tells Akira that a pure hearted person can resist the demons will and use the demon powers as their own, but if the demon takes over then they will have to commit suicide. They go to a nightclub/demon ritual and almost everyone gets possessed. Akira freaks out and gets possessed by one of the mightiest demons, Amon, the Lord of War. Thanks to his pure heart Akira claims the demon power as his own and becomes Devilman! As Akira kills the other demons, Ryo is amazed/surprised by how Akira acts. Somehow, Ryo is injured in the battle and Akira takes him to the hospital where Ryo recovers. Later, Akira visits Ryo in the hospital and finds him recovering at above-average speed. Ryo didn't merge with a Demon but he and Akira have a talk about life and nature. Later, when Akira is fighting Sirene, Ryo helps by shooting Sirene with his trusty shotgun before getting hit by her flying claw. After Akira is nearly killed by the combined form of Sirene/Kaim, Ryo heals Akira and reattaches Akira's ripped off arm, showing he has some strange powers. Later, when demons are attacking and possessing a lot of people, Ryo finds out that the real Ryo Asuka has been dead for some time and he is really Satan. To infiltrate the human world, Satan had been Hypnotized by Psycho Jenny and went out as Ryo Asuka. but Ryo's feeling of friendship for Akira turned to love for Satan and he had developed a love for Akira. Ryo goes on TV and shows a tape of Akira being possessed and becoming Devilman. After the world suffers from fear and paranoia and Miki is killed, Akira and Satan have a 20-year war that destroys the earth. In the end, Satan tells Akira that God saw the demons had evolved into what he had considered ugly, so Satan rebelled against their father (God) and the demons were sealed in ice by and with Satan. When the demons returned, humans had taken over so they tried to wipe them out. Satan tells Akira that he regrets their actions since they wiping out humans were just as bad as what God tried to do to the demons and looks over to Akira to finds that he is dead (all that is left of him is the waist up). Realizing that they just killed a man for whom they would give world and life for, Satan cries as God's angels arrive to destroy and remake Earth. Billions of years ago God created Earth, and its inhabitants along with it. However, not all of his creations turned out as God desired. Seeing these creatures as abominable, God condemned to extermination. Satan (the result of the Archangel Lucifer unintentionally merging with and dominating the consciousnesses of his slain pegasus and the female genetically altered human Yuria, but as a side effect of the merge Lucifer's original consciousness was altered as his previous stance towards the demons had changed from that of contempt to sympathy for the demons) defied him and declared that even with his authority and power God has no right to arbitrarily take lives. So Satan and the rejected creations that came to be known as demons rebelled and waged war against God and his forces. Unfortunately, Satan and his/her followers are defeated. Satan and their follower demons entombed themselves within glaciers to hide and to bide their times to recover and to go to war against God once again. After some million years later Satan was freed, only to witness a new species created by God have populated Earth in their absence and harmed the planet Earth for their own selfish gains. Seeing the planet which he fought so hard for ravaged by the new race, Satan began to hate humanity. To reclaim the world from humanity Satan devised his greatest scheme involving erasure of his own memories, dragging Akira into their war and changing him, and making people who became Devil-being like Akira having nowhere else to go but to Akira and their demonic factions. What Satan did not realize was, however, in their attempts to eradicate humanity and make the Earth for Demons, Akira Fudo, and Satan's to rule, Satan had become the very figure they rebelled against millions of years ago. Akira Fudo and his Devilman Army, who had lost their bodies and loved ones due to Satan's actions to take over Earth(which is deemed unilateral atrocity by the powerful against the powerless), could not accept the new world created by Satan.
