From The TimeSplitters Wiki

Dr. Cortez is a character in Timesplitters: Future Perfect. He appears in the level You Genius, U-Genix, where Cortez dresses as a doctor to be able to move through the lab without drawing attention.

He wears the same oufit as Brother Bartholomew, except the face mask covers up none of his face. He is unlocked when you beat You Genius, U-Genix on normal mode or harder.
