"He's coming for us.. we're both gonna die!"
— Brad to Jill, shortly before his death.
Brad Vickers (ブラッド・ヴィッカース,Buraddo Vikkāsu?) was a member of the Raccoon Police Department's S.T.A.R.S. Alpha Team. Vickers wasn't much of a fighter, and it is not mentioned as to whether or not he had served in any combat capacity before his recruitment into the S.T.A.R.S. unit. His hometown was Delucia.
Vickers was recruited into S.T.A.R.S. after its 1996 founding. An elite counterterrorism and counter-narcotics unit within the Raccoon Police Station, S.T.A.R.S. was funded through private investment by local businesses, and hired professionals from outside the police force. While known for his timid behaviour, he made up for it by serving multiple roles. As a qualified helicopter pilot, he transported the Alpha Team around the city. As a computer expert, he could deal with obtaining digital evidence. Trained in chemical protection, it was also his job to deal with hazardous substances. When on patrol, he took the one of two RS (Rear Security) positions.
On Friday 24 July, 1998, Alpha Team was sent out into the Arklay Mountains over a region northwest of the city. Having lost radio contact with Bravo Team the night before, the mission was to investigate this loss. Landing the helicopter near the derelict of Bravo Team's helicopter, it became clear that its pilot - Kevin Dooley - had been savagely killed and partially eaten. Soon after, Joseph Frost was himself attacked and violently killed by a pack of dogs hiding in the area. Terrified, Vickers took off into the air, leaving his team mates behind.
Quickly regaining his composure, Vickers made multiple attempts to re-establish contact with his S.T.A.R.S. teammates whilst flying over a mansion near where they landed. Unable to contact them due to a strange fault with their radio equipment, Vickers was not able to make contact until daylight. Flying over a helipad adjacent to the mansion, he spotted his surviving comrades battling a superhuman dubbed the "Tyrant". Having taken off with all of the team's equipment still on board, he was able to drop them a rocket launcher to use against the monster and evacuate them as the complex exploded from an underground self-destruct device.
After landing back at the Raccoon Police Station, Vickers would soon understand from the others the mansion was the site of covert bioweapons research carried out by Umbrella U.S.A., and a series of murders and animal attacks that plagued Arklay County for the previous two months was the result of an outbreak of the mutagenic t-Virus. Though S.T.A.R.S. began investigating Umbrella, the company put pressure on the RPD through bribes, and Chief Brian Irons formally disbanded S.T.A.R.S. to strike a blow to their investigation, something Vickers timidly sided with. Umbrella kept tabs on Vickers, seeing him as just a threat as any other. Nonetheless, he continued in the investigation covertly with Jill Valentine after Chris Redfield, Rebecca Chambers and Barry Burton left the city.
"The police aren't trained for this kind of situation! What could they do?!?"
— Brad commenting upon the futility of the RPD's defensive measures.
In September, a modified Epsilon strain contaminated Raccoon City's drinking water, turning thousands into Zombies. Vickers and Valentine were the only former-S.T.A.R.S. officers left in the city, but were separated until Monday 28 September. Vickers was stalked across Uptown Raccoon City by the Nemesis-T Type, a B.O.W. sent in by Umbrella Europe to hunt down and kill surviving S.T.A.R.S. members to prove its hunting skills as a valuable commodity. Fleeing from Zombies as well, Vickers made his way to the Black Jack Bar, where he finally found Valentine. He warned her of the "monster" and his experience with the collapse of the police force.
Soon after, Vickers was spotted again by the Nemesis-T Type, and was chased all the way to the Raccoon Police Station. Injured, he warned Valentine, but was immediately cornered by the B.O.W. as it jumped over the gates. Grabbed by the head and held into the air, the B.O.W. then impaled him through the head with a tentacle. While this wound should have killed him quickly, Vickers was infected with the t-Virus - either solely from the tentacle or a mixture of it and a pre-existing infection. Falling unconscious, he mutated quickly due to the highly potent nature of the tentacles' resin. Vickers soon woke up as a Zombie and walked off. Whether he was shot by survivors or left to his own devices is unknown, but he was certainly dead by the morning of Thursday 1 October when the U.S. Air Force bombed the city with an experimental thermobaric weapon.
