Why Did Dark Mephisto Turn Evil In Ultraman?

Avani is the last earth dragon in the world. Not only that, but he is also the last male dragon. The other three remaining elemental dragons, air, water and fire, are all females. Unless he mates with one of the other three dragons, the race of pure dragons will die out. Since he snubs the idea of finding a mate, refusing to allow anyone to claim him and therefore control him, he has taken over as protector of the forest. The hunters are always searching for supernaturals to force into their Arenas, a modern-day gladiator fighting ring. And now, they are capturing supernaturals to experiment on, creating a new race of hybrid creatures. Because Avani can shift his emerald-green scales into the black of onyx, those he saves have started to call him The Dark Protector. Merethyl is an elven princess. She and her brother, Yhendorn, are captured by hunters when her family is attacked, her parents slaughtered in front of her. She and Yhendorn are held captive, experimented on, until one day they find a way to escape. As they flee, Yhendorn is re-captured sacrificing himself to make sure Merethyl gets away. As she runs, the hunters chase her, trying to run her down. Avani hears her and flies to her rescue, killing the hunters that are after her. When he realizes that she smells better than anyone he’s ever smelled before, he knows he must get away from her. He cannot allow her to have the total control over him that claiming him would give her. But Merethyl has nowhere else to go and she needs Avani’s help to rescue her brother. Will Avani be able to resist the charms of the elven princess, or will he fall to her, claimed, making her his dragonrider?

Lucifer the God of Destruction, son of the infamous King of the Underworld, Hades, has come into a predicament that he isn't sure he will be able to handle. His power and anger grow daily, his father believing Kronos is trying to inhabit his body. He spends his days and nights torturing the souls of hell but it is not enough. His desire to run to Earth and destroy every living thing like his grandfather, Kronos, grows by the day. No longer thinking a mate would sate even his evilest desires, he continues to try and control himself all on his own. Goddess of Innocence, Uriel was born from Hera and her mate, Michael, an archangel. Since her birth, they have kept her hidden away, trying to keep her innocence. No one in Olympus or the Celestial Kingdom knew of this beautiful angel-like goddess, until one day she makes a glorious appearance at a baby announcement in the Underworld. Stealing the show, and completely oblivious of stares and whispers, she eats her fill of food only to be recognized by the woman-hating God of Destruction, Lucifer. What could possibly happen next? ***The female lead is extremely naive and innocent. She is unaware of the outside world and how it works, including people's true intentions***

Everyone in the Darkthorne Pack knows one thing about me. I'm human. The unwanted girl with no wolf, no rank, and no place among werewolves. For eighteen years, I've been counting down the days until I can escape the pack that never wanted me. The only person who's ever stood by my side is my best friend, Brock, an omega destined to disappoint his powerful Alpha family. Then everything changes. Brock finally shifts... and becomes someone I barely recognize. Cold. Distant. Cruel. As my eighteenth birthday approaches, strange things begin happening. My senses sharpen. My body burns with impossible power. The same elite wolves who once ignored me suddenly can't stay away. The pack's strongest males are drawn to me, fighting instincts they don't understand. Including Brock. But when my wolf finally awakens, it reveals a truth no one saw coming. I was never human. I belong to an ancient bloodline thought to be lost, one powerful enough to shake the werewolf world to its foundations. Now four powerful mates are bound to me, enemies are hunting me, and the pack that treated me like an outcast suddenly wants me at the center of everything. Too bad I've spent eighteen years learning how to survive without them. They may want to claim me. But they'll have to earn me first.

"Good can't exist without evil. But what happens when we are neither?" Elliot Harvard has assembled a team of misfits. There’s Bryan, the hot-headed elemental; Classy, who can manipulate matter; and Mello, whose art becomes reality. But among the new recruits living in the secret base, one figure stands apart: Northstar. Silent, brooding, and terrifyingly powerful, Northstar is the host of the Shadowalker—a mythical demon created to destroy life but cursed to protect it. He lives in the gray area between light and darkness, possessing knowledge that predates history. When the squad faces their first real test against a horde of monsters in an abandoned warehouse, things take a deadly turn. With one of their own infected by Dracula and fading fast, the team must rely on Northstar’s dangerous connection to the Null Void. But can they trust a demon who claims to have no emotions for humans? The training is over. The war against the supernatural has begun.

Venus has a lousy dad and an annoying stepmom. However, that's enough to end there; because her dad (who turned out to be not her real dad) threw her into darkness, which led her to another dimension called Second Earth, a world where the volts, humans with Talent, live. Like someone who feels lucky, she feels like she was given a second, more decent life. It, as it turned out, wasn't quite what she had thought. She had only been there a few days and was sentenced to death. Not to mention the fact about who her real biological parents are. As if that wasn't enough, it was as if her mind was infiltrated by a demon who claimed to be her great-grandfather. Happiness seemed to be eroded little by little from her and she felt that life as a homeless person on First Earth, her original world, would feel better than here. Her heart became more and more shrouded in gloom and she transformed into the image of someone that the people of Second Earth wanted. Being a bad person wasn't her choice in the first place, but hell could handle it, Venus thought. She was tired of being a good person. Then will her ending be as easy as she imagined? Will she be able to turn back into what one would call a good girl? Or is her path to being a sadistic and cruel person the best for her? The destiny of a dark descendant. Will her story be different?
