Carlie Cooper

After 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 exhumated. Carlie was then ambushed and taken to the Goblin Underground, where she was interrogated about Spider-Man's true identity. She refused to tell Norman Osborn, and so he transformed her into Monster.

Carlie was later cured of her transformation with a cure developed by Sajani Jaffrey, and she decided to cut all ties with Spider-Man.
