When he was forced to go underground to escape International Operations, Alex Fairchild left Caitlin in the care of relatives in Portland, Oregon. Raised by her aunt and uncle alongside her cousin Karen, Caitlin grew into a brilliant, but rather mousy young woman. Her academic skill led to her being accepted to Princeton University where she double-majored in computer science and electrical engineering.
In her sophomore year, Caitlin was recruited into Project: Genesis which she believed to be some sort of government internship. One night, Caitlin began to feel ill (due to secretly being fed drugs designed to activate latent Gen-Active abilities) and staggered out of her room to try to find a bathroom. She inadvertently stumbled into a computer room where her future teammates Grunge and Roxy were hanging out. Caitlin convinced them to go back to their rooms and was about to leave when she spotted her father's name on a computer screen.
Caitlin, investigating this, was interrupted by a security guard who clubbed her with his rifle when she tried to explain herself. The guard was about to turn on Grunge and Roxy, but was interrupted by Caitlin’s anger activating her latent gen-active abilities. Fairchild’s clothing was shredded in the process, but within seconds she was transformed from a mousy computer geek to a powerful, towering amazon.
Borrowing Grunge's shirt, Caitlin, Roxy and Grunge decided to escape Project: Genesis. Along the way, they were joined by Bobby Lane and Sarah Rainmaker. Despite their best efforts the team’s escape from Project: Genesis would have failed if not for the intervention of International Operations director John Lynch.
Deciding that I/O had to be opposed, Lynch turned on the organization and helped the teens flee to San Diego, California where he set up a luxurious safe house in the La Jolla area. Lynch promised to teach the fledgling superheroes how to make a difference in the world and to help them uncover the mysteries of who their parents were.
Because of her responsible and mature attitude, Caitlin was universally elected field leader of the team. Though uncertain of her abilities, Fairchild accepted the role and her cool thinking got the team out of more than a few tight situations. Some time later, John Lynch disappeared. But Alex Fairchild, who Caitlin was reunited with during the Fire From Heaven crossover, took up the role of mentor. It was during this period that the team relocated to the Florida Keys and Roxy and Caitlin discovered that they were half-sisters.
But the family reunion was short-lived as Alex was killed protecting his daughters and the rest of the team from the villain Tindalos. With her father dead and John Lynch still missing, Caitlin took full leadership of the team.
Though sometimes frustrated by her comrades' personal eccentricities, Caitlin cares deeply for all of them. They are all the family she has now. In return, the rest of Gen 13 look to Caitlin as both a friend and leader. Also, an accident resulted in a case of amnesia that made her believe she was Supergirl for a time, an issue that was quickly resolved.
Following the events of Captain Atom: Armageddon, Caitlin is still living with her adoptive parents when she mysteriously wakes up with a version of her familiar green uniform. Her parents take this as a cue that their apparent mission to raise her is over. Soldiers enter her home, kill her parents and kidnap Caitlin. She meets up with other familiar Gen 13 characters, Freefall, Burnout, Rainmaker, and Grunge, for apparently the first time.
Caitlin, forced to pose for prurient shoots in stereotypical hypersexualized situations, helps the other Gens to escape from Tabula Rasa, the I/O offshoot project responsible for their empowerment, protecting them and caring as a sort of rational and mother-like "hen mother" for the group. However, her time with Tabula Rasa leaves her badly traumatized and unsure about her prettier appearance, due to the motives leading them to give it to her in the first place. As the natural "leader" of the group she leads them during throughout their escape, helping Rainmaker into coping with her homosexuality and reassure her that they still could be friends even if they'll never be lovers as she hoped to, caring for Grunge when, forced to kill in self-defense, is left shattered and falls in a deep depression, warding off further plans of Tabula Rasa's men to control the Gen 13 members life, and, ultimately taking care of Burnout, blinded during the World's End event.
During Gen 13's adventures, Caitlin was revealed to be, as her Gen 13 teammates, the recipient of the soul of her original namesake, collected by the Doctor and restored in the new body. However, in this life all the Gens exhibit different tendencies, becoming progressively their own persons: Caitlin is less a tease and a bombshell, and more of a quiet, peaceful hen-mother whose quiet and collected manners stride heavily with her pin-up body.
Caitlin's role in the post-Armageddon ruins which Earth has become is now caring for the safety of her friends: when the other Gens suppose that Caitlin may be developing the Florence Nightingale Effect, Grunge dismissed it, claiming that helping friends in need is a facet of her personality, and pressures her into being more carefree for a while.
While seeking refuge in a mall, the team splits up to find new clothing. While alone, Rainmaker embraces Caitlin and the two kiss. Caitlin pushes Sarah away, who runs off. While following Sarah to apologize for acting so harshly, Caitlin notices a group of people outside the mall. She lets them in so they can get food and shelter. These people, however, are infected with the Warhol Virus and turn into Incubites. After fighting them off, Caitlin is dowsed in the blood of one of the dead creatures. After washing up the gang decides to head to the town of Tranquility.
After hitching a ride from Dr. Sin the team heads to a post-apocalyptic skate-park run by youths. While settling in a tent, Caitlin grabs Bobby and the two kiss. Rainmaker sees this and storm out of the park. After taking a break from their make-out session, Caitlin steps out of the tent and is met by Holly Denton. Caitlin is skeptical of her knowledge about Tabula Rasa and is reluctant to befriend her. Shortly after this, Megan and Dr. Cross (in child form) spray them all with a blue goo that encapsulates them all. After escaping from this, they discover that the youths at the park are cannibals. In the process of escaping, Caitlin is stabbed and starts to bleed, to her surprise. Holly uses her power to remove the stabber's skin, killing him instantly. Megan then drives up in her I.O. van and offers the team a ride.
Caitlin remained critically wounded and close to succumbing to the Warhol Virus in which Dr. Cross pledged the Gens in helping her, only in exchange for a blood sample from each of them in return. Upon arriving to the town of Malice, Caitlin, Cross and Megan were taken prisoners by the Fearsmiths after the toddlers convinced the villains that Caitlin was their mother and needed medical attention for her. Ultimately, Caitlin mutated into an incubite and slain Taipan, Stinkbug, and Nightmary. Just as her fifteen minutes were almost expire, Holly cured Caitlin with her powers at the cost of her life.
