Mr. X vs The Nemesis

Two of Umbrella's most memorable Tyrant-class monsters go mano-a-mano inside the hell that is Raccoon City.

Round One is Nemmy and the X man in their respective outfits (no Rocket Launcher for the Tentacled One), while Round Two is in their monster forms (X as the Dual-Clawed Tyrant and Nemesis in the form he fights Jill at the Clock Tower)

Hmm...The Nemesis seems much more resiliant, but I really don't know.

I think Nemesis has the edge in terms of sheer endurance (in RE3 you can fight him during every one of his appearances, ‘kill’ him, and yet he returns again later), and power. I think he’d take this one.

Nemesis appears to be more intelligent as well.
