Carlie's father was a respected officer for the New York Police Department before he died. Carlie took after her father and began to work in the medical examiner's office as a forensic expert. She was best friend to Lily Hollister. The two of them grew up together and Carlie considered Lily's father, councilman Bill Hollister, as her second father. Carlie gravitated to Peter Parker's circle of friends when Lily Hollister began dating Peter's best friend Harry Osborn, eventually becoming Peter's girlfriend for a time.
When Doctor Octopus switched minds with Spider-Man, Carlie was the only person to be told by "Doctor Octopus" he was actually Peter Parker, moments before his death. Due to the change of behavior of Spider-Man (actually Octavius), Carlie began to investigate if what she was told was true. With assistance from Yuri Watanabe, she was able to confirm that Otto Octavius was in possession of Peter's body and that Peter had died. She visited his grave, but was then surprised when it caved in, revealing the body had been secretly exhumed. Carlie was then ambushed and taken to the Goblin Underground, where she was interrogated about Spider-Man's true identity.
After repeatedly refusing to reveal the truth, the Green Goblin sprayed the Goblin Formula on Carlie, transforming her into one of them, and nicknamed her "Monster." As a result, Carlie's previous personality was buried beneath the transformation.
