The Demon King Zenon has announced that the strongest of his three best warriors will take the body of a human and destroy the human race. After a quick battle, Devilman is victorious and assumes the life of the now slain Akira Fudou. However, 'Akira' soon finds his plans utterly foiled when the daughter of his new caretaker, Miki, is revealed to him for the first time. Akira quickly falls in love with the lovely Miki, casting him a traitor with the devil clan. With his mission forgotten, Akira must now fight the minions of the Demon King at every turn to protect the woman he loves.
Two thousand years ago, the Demon Lord Dante was encased in ice by the powers of God, leaving a cult of Satanists on a quest to revive the dark master in the present. They have their sights set on Ryo Utsugi, a young man who is plagued by terrible nightmares of becoming a demon. Ryo is believed to belong to Satan, and thus is coerced by the evil doers into traveling to the Himalayas where Demon Lord Dante, and his destiny, await...
As Devilman was directly inspired by Demon Lord Dante it's no surprise that this is a good recommendation. Demon Lord Dante, having its anime version been made later than Devilman TV, has far better animation and is a lot less campy. Still, if you liked Devilman TV, you'd enjoy Dante as well.
Hanappe is a typical horny high school kid. Between watching dirty movies and having the crap beaten out of him by the school bullies, life is pretty normal. That is, until two lustful demons burst into his home through the television set, bestowing his index finger with the power to either seduce the opposite sex, or unleash a destructive blast. As much fun as lewdly brainwashing women is, the endowment comes with unwanted small-print, and Hanappe’s home is soon turned into a raucous devilish orgy!
Although Devilman is very gory and gripping whilst Hanappe revels in comedy, both have many factors in common. Coming from the same era, the animation in both is typical of the 90's. There is also an unhealthy amount of demons, sexual encounters and questionable treatment of women. Definitely not family friendly, there is something about both of these anime that will appeal to the fantasy/action loving pervert.
Shinichi Kuruma is an experiment gone awry. With the ability to summon a lion and bear from his body and superhuman strength, he is one of many 'New Humans' created by Shinichi's own father, Genzou Kuruma, who wants to control the fate of those who will inherit the Earth. Alongside a girl named Ayaka who was injected with Shinichi's special blood, Shinichi must stay out of the reach of the other New Humans and scientists who wish to use his lifeforce to revive God; but most importantly, he must find a way to exact his revenge on his father.
While Phalanx TV is far more gory and extreme than Devilman TV, I think it's possible you'd like it as well. Both have ridiculous creatures, violence, gore, and nonstop battles that will appeal to the same kind of fans. Phalanx frankly could have come right out of Go Nagai's mind.
