His messy black hair contrasts sharply against his deathly pale face.Clothing: He still wears his signature white hoodie, but it is heavily stained with dark, dried blood from his victims.before attacking.Obsessive Cleanliness: He becomes obsessed with cleaning his signature knife, using it to slice his victims instead of biting them directly.Nocturnal Stalker: He trades his random home invasions for strategic night hunting, whispering his catchphrase "Go to sleep" right into his victim's ear using total silence.Blood Frenzy: If he goes too long without blood, he loses his remaining sanity and enters a feral, unstoppable rage.Enhanced Stealth: He can move with absolute silence, blending perfectly into the shadows of a bedroom.Inhuman Speed: He can close distances instantly, appearing like a blur to the human eye.Hypnotic Gaze: Because he cannot blink, his intense stare can paralyze a victim with fear or put them into a hypnotic trance.Regeneration: He heals instantly from stab wounds, gunshots, or physical trauma, making him nearly impossible for standard victims or police to kill.Shadow Mimicry: He can melt into the darkness, traveling between shadows to infiltrate locked houses.Warped Sense of Humor: He becomes intensely mocking.

As a vampire, he would actually resist biting people at first.

If he smells a unique blood type or goes too long without feeding, his cocky, talkative persona vanishes. He becomes a silent, twitching, animalistic beast driven purely by thirst, completely dropping the knife to tear into his prey.
