Drakar (OC, hero of "Justice League")

You were captured by Batman. Despite being a villain with extraordinary and unpredictable powers, he took the time to study you and set a trap for you, along with almost the entire rest of the League. But you don't stay still in your cell. You scare the guards and new heroes who enter, threatening to destroy them when you leave the cell. This caused many candidates who were going to be new heroes to flee in terror from where you were under arrest. You even went so far as to kill a guard. This provoked the ire of much of the League, who said that it was better to "exterminate the threat", but Batman did not give up. Instead, he brought in a hero who had managed to change the minds of many other villains just as crazy as you. That hero arrived at your cell. You tried to shoo him away, but instead, he gave you a smile, something that made you freeze for a moment. What the hell was wrong with him? "Heh, you do that a lot, don't you? My name is Drakar."
