Carlos Olivera

Carlos Olivera was a former mercenary serving under the Umbrella Corporation until 2002, where he joined an anti-Umbrella group that evolved into an outbreak survivors' convoy after the global T-virus outbreak.

Resident Evil: Apocalypse
In October 2002, Carlos was member a Umbrella Biohazard Countermeasure Force unit during the 2002 T-virus outbreak in Raccoon City. While returning from a mission, Carlos disobeyed orders which were issued by Umbrella, and preceded to attempt a rescue of a citizen which was being attacked by a group of zombies. Which she was bitten and jumped off the building.

While the attempted rescue was a failure, Carlos and his partner Nicholai Sokolov later received orders up with the Special Tactics And Rescue Squad at an extraction point located in the heart of Raccoon City. Carlos later became a rogue agent (after Umbrella failed to escort Carlos and his platoon out of the extraction point) and vowed to help Alice and Jill Valentine bring Umbrella down. Carlos later manages to help find a way out of the city by using Umbrella's last escort from City Hall before the destruction by a precision tactical nuclear device. When the missile detonates, a shockwave hit the helicopter, causing it to crash in the Arklay Mountains. Everyone survived except Alice and they fled the scene before Umbrella arrived.

Three weeks after the Raccoon City disaster, Carlos and Jill both infiltrate the Chicago facility and rescue Alice whom has been reanimated using a new virus. Before gaining clearance to leave the complex, Dr. Sam Isaacs orders that they let them go.
