Manuel Mendoza

Private Manuel Mendoza was an infantryman in the UNSC Marine Corps and a member of Fire Team Charlie. He participated in the Battle of Installation 04 in September 2552.

Crash Landing on Halo
Manuel Mendoza was one of the Marines stationed on the when it was attacked by the Covenant, marking the beginning of the Battle of Installation 04.

After boarding a lifeboat, he survived the crash landing on Installation 04, becoming the infantryman at the receiving end of most of Sergeant Johnson's shouting and yelling. During the events of the crash landing, he fought alongside the Master Chief, until he was evacuated by Echo 419.

Encounter with the Flood
"I have a bad feeling about this..."

- Private Mendoza, before the Flood outbreak.

Later on, he was part of Fireteam Charlie, which was led by Captain Jacob Keyes and Sergeant Johnson, to find a supposed Covenant weapons cache that a captured Sangheili, 'Qualomee, had uncovered and disclosed to them in passing.

Instead, the so-called "cache" turned out to be a Flood Containment Facility. Fireteam Charlie was immediately ambushed and, save for Sergeant Johnson, was assimilated into the Flood and turned into Combat Forms. Though Mendoza held off the Infection Forms for a while, unlike his comrades, he was also later assimilated into a Combat Form. Shortly before he was infected, he attempted to flee the area, against Keyes' and Johnson's orders.

A few hours after infection, John-117 found Mendoza in the structure and attempted to communicate with the Marine, unknown that his consciousness was already taken over by the Infection Form. Mendoza attacked the Spartan and took three entire 8-gauge shotgun shells from Master Chief's Shotgun, with the results both "spectacular and disgusting". As the corpse-like horror came apart, the Spartan saw that one of the small, spherical creatures had taken up residence inside the Marine's chest cavity and seemed to have extended its tentacles into other parts of what used to be Mendoza's body.

Quotes

 * "Why do we always have to listen to this old stuff, Sarge?" - Private Mendoza, upon listening to flip music.
 * "Hey, if the Covenant wanna' wipe out this particular part of my history, that's fine by me." - referring to flip music again.
 * "Everywhere... I don't... There! Mira!" - When the Flood Infection Forms started to appear.
 * "Wow, this is loco! I'm outta' of here!" - When fighting the Flood Infection Forms.
 * "And my mama wanted me to be a doctor!" - After killing some Covenant.
 * "I have a bad feeling about this..." - Moments before encountering the flood.

Trivia

 * Like Jenkins, he has become a very popular character even though he is hardly mentioned.
 * There is also a glitch in Halo: Combat Evolved that allows you to get back on board the Pelican in the level 343 Guilty Spark . Once the Pelican lands, the player may run around the perimeter of the level, where Private Mendoza stands alone. If stuck with a plasma grenade, his body is thrown surprisingly high and far (almost comparable to when the Sputnik Skull is activated in Halo 2).
 * Mendoza will run toward the door even if he doesn't have any Infection Forms on him.
 * When the Master Chief ran into the combat form that used to be Mendoza, he tried to speak to him. This could be due to the fact that Mendoza was the first human combat form to attack the Spartan-II, who, up until that point, assumed that the Sangheili forms were fighting him out of free will. Similarly, Major Antonio Silva had captured the Flood-infected Private Jenkins and interrogated him, even reassuring him that the medics could help him.
 * Mendoza dislikes flip music, which Sergeant Johnson likes.
