Resident Evil Viral

Let me know if you need anything else about Resident Evil. :P

Basically he split after Res 3 and now can't be found

Well this is the information I was able to get.

A mercenary hired under the Umbrella Biohazard Countermeasure Service (U.B.C.S.), he was a member of the Alpha Squad within the Delta Platoon and was in charge of rear security and weapon maintenance. His rank in the U.B.C.S. was Corporal. Prior to his involvement with the unit, he was a member of an Anti-Government guerilla force in an undisclosed region of South America. He uses an M4A1 carbine rifle and wears a green fatigue shirt and a black tactical vest with the Umbrella logo displayed predominantly on the back.

When news of the t-Virus outbreak hit, he was sent in with a unit to the heart of the disaster in the hopes of rescuing any survivors. However, in the heat of battle, Carlos was forced to fight for his own life. He managed to aquire a Radio (possibly from his Units communications officer), where he transmitted a plead for help. Ex-S.T.A.R.S. member Jill Valentine heared the transmission in the Raccoon City Police Department.

However, by the time she met Carlos, he was only one of as little as three Platoon Delta members. The other two, Delta Platoon leader; lt.Mikhail Viktor and B Squad member Nicholai Ginovaef, had taken cover in a tram, whilst Carlos searched for help.

He became immediately smitten with her, but Jill rejected his advances. At first, Jill was reluctant to trust Carlos, due to his affiliation with Umbrella and macho attitude, but she quickly learned that Carlos was almost unaware of the company's nefarious deeds and was simply an expendable pawn to them. The two teamed up and managed to escape the Downtown area of the city and into the St. Michael Clock Tower, where Jill fought an experimental Tyrant known as the Nemesis.

As a result of the battle, Jill became infected with the t-Virus after being struck by one of Nemesis' tentacles. To help save her, Carlos went to the Raccoon General Hospital and managed to prepare a vaccine that cured Jill from her infection. Afterwards, he proceeded to an Abandoned Factory near Raccoon Park and escaped with Jill on a Helicopter.
