Bonnie Barlow was born June 6th, 1996 in Las Vegas, Nevada to an abusive father which resulted in her running away when she turned 14 years old to join a traveling circus.
While in the circus, she obtained the nickname "Bubbles" due to her extra-friendly and sassy attitude. As a result to this, the ring leaders of the circus brought in an outside group to break her and other crew members down and act in a very exact and precise manner. They stripped the crew members of all morals, human connections and sense of feelings, to turn them into "stars" of the circus. The circus members were just dancing monkeys who did what they were told.
Bonnie specialized in acrobatics along with three others. They had to train for hard and lengthy sessions with the very sinister group the ring leaders had hired. They trained multiple hours long, twice a day. It was physically and mentally draining to those who did it. She started to lose her sanity as the days went by. Due to the severity, she slowly began to develop small voices in her head which have gotten louder and more intense over time.
In addition to the physical training, they had other sessions a few times a week where a group of men in suits would mentally break the crew members through any means possible. In one of her last "normal" sessions, There was a man in a dark suit who would break her down but Bonnie wouldn't lose her last grasp on humanity she had left so they called in a new group. A man in an all black suit and mask walked in, examined the room and Bonnie, then executed the man in front of Bonnie and walked out. Bonnie was left in the room with the body and had sessions once a day in the same room. She wasn't allowed to sleep and was given minimal amount of food and water for multiple weeks while she sat in the middle of a dark room with the body of the dead man. Over the course of two months, she had been completely broken down and snapped. All morals and humanity she had were gone.
Months went by and she traveled the country with her circus crew. She performed with two other acrobats, one of the acrobats didn’t make it through the ring leader’s “grooming trial period”. She went day by day, not questioning how or why she was putting herself through this, she just went through the motions and did what the ring leaders asked of her.
While stopping in a show in California, a few female bikers caught the eye of Bonnie while she was sitting outside smoking a cigarette after the show. For some reason, the female bikers connected with her and saw that Bonnie was broken and in need of help. The three female bikers continued to come to the next two shows in California the following nights and on the last night, they came up with an escape plan to break out Bonnie.
She began to travel with this new group of female bikers who called themselves the Sisterhood. When they asked Bonnie if she would like to be called Bubbles, she quickly denied as it brought back bad memories but chose the name Banshee instead to use as a biker alias.
Banshee traveled with the Sisterhood for awhile but left to travel the world on her own for a bit. During this time, she spent a small period in a psych ward in Carcer City. She eventually faked her way out by pretending she was normal and sane but they diagnosed her with a minor case of paranoid schizophrenia. She ended up making her way back to Los Santos after multiple nights of partying, doing cocaine and gambling and reunited with Socks, one of her sisters from the Sisterhood. Socks invited Banshee to join the Chaos Crew, a group of mercenaries who will accept any job for money. Since being in Los Santos, Banshee has stopped taking her anti-psychotic medication and the voices in her head slowly get worse.
