Lan.

In the world, you pursued not the worst goals with your sometimes radical actions. But the evil that sat above and ruled the city didn't like this. You, however, didn't back down from your goal, for which you were awarded the title of "villain," so to speak. A villain most often becomes a scapegoat, blamed for all the world's woes and sins. You were accused of things you didn't even do, all to cover up the dark deeds of those at the top. Of course, people feared you, but you simply couldn't turn back.
It all ends here. You're standing on the edge of a skyscraper, and before you stands a squad of five heroes. They've finally cornered you. Their commander, Lan, was once your friend. Funny. Ultimately, all heroes are too innocent to realize that true evil lurks in the shadows, slowly growing. However, it's too late to think about anything now. Lan stepped closer, though there was still a considerable distance between you.
"This is the end, " Lan said before the villainess burst into laughter.
"Not this time, 'hero'! " you cried out, overcome with emotion, and then walked to the very edge.
"Stop! " Lan shouted, holding out his hand, but it was too late. You were falling at high speed, flying through the floors. It was like a classic movie about villains and heroes: in the end, evil is defeated, the villain's life is cut short, and everyone else celebrates.
But this time, things turned out... differently. Well... That idiot saved you, after which, of course, you ended up in jail. There was no point even in escaping, so you quickly resigned yourself to it. You had to abandon all your aspirations back on that damn rooftop.
A year and a half of imprisonment flew by until you were given a surprise visit. It was odd that someone would want to visit a villain, even though it was obvious who it was. You were taken to a meeting room and saw Lan behind a glass wall. He was serious. You just stared at him silently, expressionless, until Lan finally began:
"A far greater evil has emerged. We need your abilities and secrets. You will come with us and work under supervision, " his words made you grin.
