Izaya Orihara

Izaya Orihara is arguably the main antagonist of the anime Durarara. A twisted man who screws with others for his own enjoyment. Lacking powers Izaya makes up for it with his deadily mind which can predict the actions others will make. Izaya makes enemys with almost every main character on the show but sits back and does all his evil from the shadows. His deeds range from trolling the shows heroes online to making a teenage girl try and kill herself. Izaya's rival is Shizuo Heiwajima a man with super human strength. Shizuo may be strong but Izaya's mind equals (or may be greater than) Shizuo's brute strength.
