"I'm not going to let anything happen to you, the world needs you!"
— Sherry to Jake Muller

Sherry Birkin (シェリー・バーキン Sherī Bākin?) is an American federal agent attached to the Division of Security Operations. As a child, she was placed in protective custody after her parents' deaths during the Raccoon City Destruction Incident. During the outbreak, Sherry was infected with the G-Virus but was treated with the vaccine soon after. Because of her exposure to the virus, Sherry gained lifelong regenerative abilities.

Years later, her G-Virus laced blood would be used by bio-terrorist and Neo-Umbrella leader Carla Radames to engineer the C-Virus and its enhanced strain. It was primarily used during the 2012-2013 Global Bioterrorist Attacks.


Early life

Sherry was born around the year 1986 to Doctors William and Annette Birkin, two virologists who took part in t-Virus research at Umbrella's isolated Arklay Laboratory.[3] Sherry's relationship with her parents was strained due to their busy work schedules and, despite their early 1990s transfer to NEST in the industrial district, she was frequently neglected. Her parents were senior researchers of the G-Virus Project, a eugenics project that oversaw the creation of Golgotha, a Progenitor strain they believed could be used to improve the human race.[4] Little else is known of this stage of Sherry's life, although she was enrolled as a student at East Raccoon Elementary. Her mother also entrusted her with a locket, disguised as her 11th birthday present, that was related to her and William's research. As a potential security risk, Sherry's safety was important to her parents, who wanted her to stay away from strangers who could be after Golgotha.

Raccoon City Incident

On the night of Tuesday 22 September, the Umbrella Security Service infiltrated the laboratory, shot Sherry's father, and stole his samples of Golgotha. With the single remaining sample, William infected himself, transformed into the monster simply known as "G" and killed the attackers, but released the t-Virus into the sewers in the process.[5] The virus eventually spread to Raccoon City's drinking water. As the t-Virus showed itself on Thursday 24 September, it reached a critical mass that eventually turned tens of thousands of residents into mutants, overwhelming the efforts and resources of the Raccoon Police Department and Raccoon Fire Department to stop the outbreak. Sherry was pulled out of her lessons at East Raccoon Elementary School and made her way to the police station, though found it a dangerous environment with more people transforming from the contaminated water.

Keeping away from the violence, Sherry took to hiding around the police station. On the night of Tuesday 29 September, she met another survivor, Claire Redfield, who was new to the city searching for her missing brother. Redfield had entered the building along with rookie police officer Leon S. Kennedy. Leon became aware of Sherry during his search of the building and resisted the urge to commit suicide in order to keep her safe,[6] though he saw little of her. While traversing the sewers, she fell and was parasitized by her father.

Sherry's condition deteriorated rapidly due to the progression of Golgotha infection by the parasite. Sherry was taken to NEST by Claire and was put to bed in the security room due to her fatigue while Claire searched for information on how to create the DEVIL vaccine, using information gathered from a brief encounter with Annette. Sherry was successfully treated with the vaccine before it had time to completely transform her, though the alterations to her genome were not corrected. Sherry, Claire and Leon boarded the escape train at NEST's bottom platform and escaped the facility as it self-destructed.

It was soon discovered that William was also on board, and began destroying the rear carriages, still responding to his need to track down Sherry. He was soon after killed in an explosion, either by the train itself being destroyed or the carriage being decoupled and consumed by the explosion from NEST. At the tunnel's exit, the three found themselves in the plains of Arklay County. Though they initially stayed together, Kennedy began pressuring Redfield to leave him and Sherry behind and continue searching for her missing brother.[7]

Government custody

Kennedy and Sherry were soon after located by the authorities, and she was placed in state custody, and a government department sought to use her for their own Golgotha research. Her safety was guaranteed by Kennedy, who accepted an offer to work as an agent in their new Anti-Umbrella Pursuit and Investigation Team.[8] Due to the severe threat posed by people such as Dr. Albert Wesker, Sherry was kept tightly in the household of Derek C. Simmons, a leading American civil servant who planned to use her for private research following the closure of the American bio-weapons project. During her years in custody, Simmons' team were able to develop the C-Virus from her own regular blood sample extractions.[9][10][11]

Government work and Global Bioterrorist Attacks

Sherry as a federal agent.

With the death of Dr. Wesker in 2009 at the hands of the BSAA operative Chris Redfield, Sherry was offered the chance to be free of her protective custody if she were to gain employment as one of their agents. Having grown up increasingly aware of the effects of bioterrorism, Sherry agreed to the offer.[9]

In December 2012, Sherry served in the Division of Security Operations, a government organization built to investigate and combat bioterrorism. By this point, the near-completed C-Virus viral weapon was being tested across the world and had made its mark in Edonia. Sherry received orders to locate Jake Muller, the son of Dr. Wesker, and bring him back to the United States so blood samples could be taken for vaccine research. Their escape from the city was arduous, in part due to Muller's affiliation with the Edonian Liberation Army making him a target for the BSAA. After arriving at the city hall, the two were picked up by a BSAA helicopter and flown out of the city. During the flight over the mountains, they were attacked by the paramilitary unit, Neo Umbrella, and crashed. As she and Muller trekked across the mountains, they were captured by the Ustanak and the C-Virus' creator, Dr. Carla Radames, and taken out to China.

Sherry got to see Kennedy again in China.

After six months of experimentation by Neo Umbrella while sealed within a laboratory complex, Sherry and Muller finally made their escape, travelling through a medical facility and later speeding down the streets of Lanshiang, all the while being chased by J'avo. Regaining contact with Simmons, Sherry was ordered to rendezvous with him at the Kwun Lung building in Koocheng. En route, the pair ran into Agent Kennedy and Helena Harper near the ruins of a downed passenger airplane. From them, they learnt that Simmons was responsible for the recent bioterror attacks, but she and Muller continued on to see Simmons in person. Arriving at the building just after Kennedy and Harper, Sherry demanded the truth, and further discovered President Adam Benford had been killed in one such attack. Jake and Sherry tried to escape as Simmons' bodyguards began shooting, but were captured by J'avo loyal to Dr. Radames, who had chosen to betray Simmons.

Sherry and Jake woke up in an underwater laboratory complex on the Chinese coastline.[12] There, they discovered the BSAA agents Chris Redfield and Piers Nivens, who arrived at the request of Agent Kennedy. When a giant cocoon hatched, the four were forced to split up, Sherry and Muller made their way onto a train tunnel in the facility, where the mighty Ustanak appeared again for a last showdown. The two were able to kill the creature and escape the facility's destruction on board the train.

After the events of Lanshiang, Jake handed over his blood sample to Sherry and left. Sherry, inside an airplane, received a message from Jake saying that he lowered his original asking price of fifty million dollars to just fifty. From his blood, a vaccine for the C-Virus was distilled, and the outbreak was gradually contained.
