Yan enjoys being a vampire a great deal. He views working with his brother as an excuse to kill people, torture them, drink their blood and otherwise participate in wanton acts of depravity and slaughter. He also likes to talk, a lot. He is constantly shooting off his mouth, filling his dialogue with random profanities and threats. And he laughs like a psychotic madman. This all largely because he is a psychotic madman.
Unlike his brother, Yan does not show any special abilities far beyond the typical “freak chip” vampire qualities (strength, speed, near invulnerability, etc). He is more powerful than your average vampire, however. He makes up for this in his use of high-powered weapons, dirty tricks and sheer insanity. Yan’s disregard for his own welfare, even compared to other vampires, can easily catch most people off-guard.
