Perez (Marine)

"Sir, Corporal Perez, A Company, CP's this way."

- Corporal Perez

Corporal Perez is an UNSC Marine assigned to "A" Company of the 405th. He fought in the First and Second Battle of Earth, as well as the Battle of Installation 05.

Background
In Halo 2, the Master Chief met Corporal Perez inside a building in New Mombasa where some Marines are holed up. He leads the Master Chief to Sergeant Banks' position on the roof, and then he simply becomes another background Marine. Based upon his use of the expletive "coño" during the trailer, he is presumed to be of Spanish nationality or descent.

Perez is mentioned, but not seen, during the Battle of the Library in which the UNSC and the Arbiter race against each other and the Flood to gain possession of the Index, which the Covenant call the "Sacred Icon". The cut scene shows Miranda Keyes reaching for the Index with Sergeant Johnson saving her after the Flood tentacle fails to hold. He says a short comment to her, and then he yells out, "McKenzie? Perez? How's our exit? Do you hear me, Marines?" That's the last link to them from the game. As the Arbiter approaches Keyes and Johnson's position within the Icon's chamber, he steps over the remains of two human marines, presumably McKenzie and Perez.

Theories & Speculation
It is likely that the two were acting as sentries while Keyes and Johnson attempted to retrieve the Icon, but were eliminated by the Flood or the Arbiter himself. This is not certain, however, and others have theorized that Perez and McKenzie were among the Marines rescued by the Master Chief on High Charity, or the two rescued by the Arbiter on Installation 05.

Trivia

 * He is probably named after the Bungie programmer Adrian Perez.
