Member of the U.B.C.S. Delta A unit. His rank is Corporal. A young mercenary with Native American blood in his veins, he also was active in anti-government resistance in South America. After government forces wiped out his organization, he was scouted by the Umbrella Corporation to be their mercenary coordinator and joined the U.B.C.S.

He's a warm-hearted man who jokes around a lot. Perhaps because he was raised amidst violence, he's brave enough to throw himself in the middle of danger. Even though he's young, he's very well acquainted with firearms from the Eastern Bloc countries and so he's in charge of weaponry at U.B.C.S. He also takes care of rear support, guard duty, weapon maintenance and local procurement. However, Carlos's abilities as a mercenary don't stop there. He's also extremely skillful at driving large vehicles and piloting helicopters and Cessna aircraft.

Carlos was loaded with heavy weaponry and dispatched on a private rescue mission by Umbrella Corporation. He was equipped with a tactical vest, leg holster, kneepads and the latest M4A1 assault rifle with multiple extra ammunition. But after an unexpected defeat, Carlos found himself in a predicament. After somehow managing to escape the zombies, he encountered Jill Valentine while looking for an escape route and the two agreed to work together. For Jill, Carlos provided strong emotional support. Without him, Jill would not have been able to survive from the T-Virus.

Although it's not clear what happened to Carlos after escaping Raccoon City, it's certain that he carried a lot of anger towards his bosses at Umbrella.
