Tyrant (Resident Evil 2)

This mysterious man will follow you around the R.P.D. Building in the second scenario. His intentions are unclear, but he doesn't hold back when you encounter him.

With enough bullets you can bring him down, but it's just better to avoid him. He only has two main attacks, either a swing with his fist, or a full-on slam with his arms. When he come to take a swing at you, step back so he misses, then quickly run past him. The reward for bringing him down is a small amount of ammo, the type and quantity depend on whereabouts you encounter him.
