I'm a Villain, So I'll Take Over The World! - Chapter 2 Test Ride

Bob was a good guy. He had done everything you were supposed to do. He exercised, he kept to a healthy diet, he'd studied hard, gotten excellent grades, and was working towards his masters. Somehow, things just weren't working out for him like he'd been told they would. He was stuck in a thankless position, constantly passed over, and it seemed that the only being on earth that cared about him was his cat.

Then things got worse.

Never back a man into a corner unless you want to find out just how hard he can fight.

“Can you be useful to me?”

“I… I can be…”

The first time they met, she knelt trembling before him, begging for shelter. The slave caught his interest, and he brought her back to his palace.

She could’ve never imagined that in one night she’d go from a spoiled little slave princess of a defeated kingdom, to becoming a powerful prince’s pet.

He kept her by his side… spoiled her, cared for her, loved her, and gave her meticulous care and high status. Whatever she wished… she could do so under his name.

But, she angered him and chose to run away. He captured her within a day.

“Don’t forget, my little dearest, everything I have given you can be taken back…”

In a spur of anger, she hit him, her feeble hands striking against the flesh of his cheek. Gnashing her teeth in anger, she said, “Do you have the ability to take my child back?!”

In the not-so-distant future, a group of Earthlings find themselves mysteriously transported to the Nexus Realm, a fantastical world besieged by monstrous creatures.With no way out of the craziness, they reluctantly joined forces with the realm's inhabitants to combat the constant threat of these otherworldly beasts.To defend the Nexus or Nexaria, powers were bestowed upon them with the promise of returning home after successfully repelling the monsters dangling before them like a carrot.Years passed, and the initial camaraderie between the heroes slowly began to crumble. Still, the Protagonist, Adrian Fenrir, with his power known as Analysis, played a crucial role in understanding the monsters' patterns and weaknesses. However, as the group became more adept at handling the threats, they grew increasingly independent and, perhaps, arrogant.One day, due to a series of mishaps, Adrian found himself surrounded by assassins. He tried his best to drive them off but failed and met a bitter end. It didn't take long for the assassins to do their work, and as per the contractor's request, they decided to dispose of Adrian's corpse by selling it to a mad scientist known for his experiments with creatures from the Nexaria.In need of a fresh subject for his latest project, the scientist transformed Adrian into a chimaera, a fusion of humans and monsters to be sold as a weapon for war.However, the scientist's plan backfired when Adrian, against all odds, regained consciousness within his chimaera body. Fueled by rage and the memories of his betrayal, Adrian seized control over his new body. Now reborn as a chimaera with the ability to absorb organs and gain the powers of other creatures, Adrian vows vengeance upon the mysterious contractor who sent the assassins for him.Once a battleground against monsters, the Nexaria now witnessed a different kind of conflict—one driven by betrayal, revenge, and the extraordinary powers of a vengeful chimaera.

Waking up in the body of a 6-year-old boy a few years before Cintra is destroyed, Madara receives a system that gives him the ability to gain the powers of Uchiha Madara.[The peak of Uchiha Madara's system is before he becomes the ten-tails jinchuuriki.]The system's percentage does not stop Madara's power, but rather the system's release. After all, I don't want to see a character who goes around killing everyone from the beginning of the story.
