Paranoid Marine

The Crazed Marine was a UNSC Marine, originally a member of Fire Team Charlie.

This UNSC Marine was presumably a member of Fire Team Charlie, deployed to what was thought to be a Covenant weapons cache. In reality the fire team was headed for a Flood Containment Facility.

He was inserted into the swamp by the Pelican Victor 933, along with Sergeant Johnson, Private Bisenti, Private Mendoza, and Private Jenkins. The squad met up with Captain Keyes, along with Privates Kappus and Riley, after discovering the remains of a dead Elite. After entering a large hall, the squad was ambushed and attacked by "small, squid like creatures". This Marine witnessed the death of almost his entire unit, and fled the battle, hiding from the Flood.

Long after the Flood had finished their massacre of Marines and Covenant alike, Spartan-117 came across this Marine. The soldier was a wreck, firing at anything that moved with his M6D pistol, and hollering about "monsters." In Halo: The Flood, it is said that the Master Chief told him to leave the building, but the Marine ignored him, and crawled into a fetal position, whimpered, then fell silent. He also told the Chief to "find your own hiding place!" and claims to be able to "hear" them when the Chief approached. It is unknown what happened to the Marine after the encounter, though it is possible he was killed by the Flood. If not, he almost certainly died when SPARTAN 117 destroyed Installation 04.

Trivia

 * His fate is unknown, as the room he was in locks after the Chief comes back out. However, it is possible he was in the structure's "basement", as a body is found on a flaming platform, and a pistol lies next to him.
 * The Marine may have been found by the second squad, but killed along the way and left behind.
 * If the player sticks the Marine with a Plasma Grenade, he will stand up with his arms out at his sides like a cross.
 * A homage to the Halo: Combat Evolved, the Halo 3 Crazed Marine is voiced by the same person, and features similar mannerisms to the original. Found in Floodgate (Level), in the Flood-ravaged Command Center. Whether this Marine is intended to be the same character as his counterpart from the first game is unknown, though improbable.
 * In Halo: The Flood, Master Chief is actually shot by the Crazed Marine, but he immediately took the M6D from the Marine and tried to talk sense into him, before he crawled back into a fetal position.
 * He can be killed with one shot by any weapon.
