Kevin is a mute serial killer who resides at "The Farm", a shadowy retreat owned by the powerful Roark family. Though he is never shown speaking a single word, his protector Cardinal Roark claims that he has the voice of an angel.
He kills prostitutes, mounts their heads on a wall like hunting trophies, and cannibalizes their remains, giving the leftovers to his pet wolf. He is sheltered by Cardinal Roark, to whom he supposedly confessed being tormented by guilt over his crimes. Being close with Cardinal Roark, he is also well known to the family and is good friends with Roark Junior. He appears as a small, shadowy figure with occasionally glowing glasses and razor-sharp fingernails that he uses as weapons.
Kevin is preternaturally quick and silent, and ferociously skilled at martial arts. Marv laments that Kevin is the only person to have ever successfully snuck up on him, and is also the only person to successfully beat him in single combat. Portrayed by Elijah Wood who was perfectly suited for the role.
