9. T-00
This sinister BOW turns up in RE2 to give Claire and Leon the run around. In the Darkside Chronicles, he was sneeringly referred to as 'Trenchy' by Leon due to his giant trench coat. He is basically a very large monster who looks human but has super human powers. He stalks the Raccoon City police department looking for Claire and Leon, knocking down walls when he has to. If he gets a grab of your character he will lift you up in the air and slam you down onto the floor, inflicting immense damage. T-00 is a scary monster, and one that I would run away from rather than engage with. If you shoot him enough, he will fall unconscious and his body will bear gifts but you better get outta there quickly before Trenchy wakens up! Whoever manufactured Trenchy should be given an award for his unremitting stamina and persistence. Never have I seen such a dedicated monster, evolving into so many forms in order to pursue a mere four people. And this is why he is such a legendary monster in the RE series.
