Perez (Marine)

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

- Corporal Perez, upon greeting the Master Chief during the level, "Metropolis".

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

The First Battle of Earth
In Halo 2, the Master Chief met Corporal Perez in the proximity of a Marine field command post in New Mombasa where some Marines are held up, wounded, and making a last-ditch stand against the Covenant occupation. He led Master Chief to Sergeant Banks' position on the roof, and then he simply became another background Marine. Based upon his use of the expletive "coño" during the trailer, he is presumed to be of Spanish nationality or descent.

Search for the Index
Perez is mentioned, but not seen, during the Battle of the Library in which the UNSC, and the Arbiter race against each other to gain possession of the Index, while the Flood try to stop them from getting possession of the Index. McKenzie and Perez were (along with Miranda Keyes and Sgt. Johnson) evidently the only two marines to survive to reach the Index chamber. McKenzie and Perez were tasked with securing the exit from the chamber. It is unknown what exactly happened to them during this endeavour: they were either killed by the Flood or captured by Brutes, as when Johnson radios them for their status they do not answer. The Arbiter arrived shortly after, capturing Keyes, Johnson, and the Icon.
