Bitores Mendez

You carry the same blood as us, it seems.

Bitores Mendez was the village chief whom Leon S. Kennedy faced shortly into the scenario of Resident Evil 4. Some of his distinguishing characteristics include his imposing stature, fake left eye and resistance to firearms. He leads the hunt for Leon and Ashley Graham earlier in the game, leaving behind notes of his strategies to trap the two.

When Leon first encounters Mendez, he is unable to subdue the chief and is knocked unconscious. Later, Mendez begins to strangle Leon, but reconsiders once he realizes that Leon is infected with a Las Plagas parasite. If Leon pursues Mendez after that point, Mendez will attempt to kill him again, but will be distracted by Ada and will leave Leon to chase her.

In his final confrontation with Leon, Mendez traps Leon in a building by twisting the metal door handles together with his bare hands. After being damaged by an exploding gas barrel, Mendez reveals his true, inhuman form. His fingernails become long, sharp talons, a pair of segmented limbs burst from his back, and his torso is split by a thick, spinal column-like structure edged by tiny, moving legs, greatly increasing his already impressive height. Even severing him below the waist will not kill him in this form, and in fact increases his mobility; he uses the limbs on his back to grab onto wooden beams.

It is unclear if this level of assimilation would eventually be demonstrated by all those infected by Las Plagas, or if Mendez was subject of experimentation like many of the game's monsters.

Using firearms from various merchants, Leon eventually kills Mendez and escapes from the barn, reuniting with Ashley and heading onward to find their way back to civilization.
