Christopher "Chris" Redfield is one of the main protagonists of the Resident Evil franchise. He is a former member of the S.T.A.R.S. unit. He is now a member of the Northern American team BSAA (Bioterrorism Security Assessment Alliance), an anti-BioTerrorist group tasked with stopping bioterrorism around the globe. He is the older brother of Claire Redfield and the partner of Jill Valentine.
His muscular size has changed throughout the series, starting out as an average sized person and ten years later, he is seen as a big brute. In Resident Evil 6, he becomes more of a tragic hero, as a result of losing his men to a bioterrorist, whom he believes is Ada Wong. He relentlessly pursues her to kill her, but gives up on his vengeance to save the world from the virus. Redfield then returns to his role in the BSAAA, and later works with Blue Umbrella to stop the infection in Dulvey Parish, Louisiana. After dealing with the infection in Dulvey, Redfield became obsessed with stopping Mother Miranda, a biologist and cultist who wanted to Ethan and Mia Winter's daughter, Rose to bring back her late daughter.
