Ratman

Ratman is a rat-like creature in GTA IV. He is a very debated myth since many people cannot find him and many believe he's just another non-existent myth, like Bigfoot.Others think he is a homeless person mistaken for a "ratman". He is said to live underground in the subway, near the abandoned subway station. He runs faster than the NRG 900 and it is said that if you shoot him he will come back and kill you. When you're dead, he supposedly nibbles on your face until you return to the nearest hospital.
