Ruv tends to be introverted and not interact with other people. The only people he likes to interact with is those who he trusts. Despite being shy around strangers, he seems to have a near emotionless mindset, sociopathic tendencies, and extreme hostility against people he does not like or any stranger in general. If he wants to kill or hurt someone, he will not hesitate to do so. He cannot smile because of an injury to his face muscles. He also speaks with an Russian accent, obviously.
