Comics Mirage Comics In the original Mirage Comics storyline for Teenage Mutant Ninja Turtles, April O'Neil was a skilled computer programmer and assistant to a famous yet nefarious scientist, Baxter Stockman. She helped program his MOUSER robots but, after discovering Baxter was using them to burrow into bank vaults, she fled his workshop. Robots chased her into the sewer where she was promptly saved by three of the Turtles. The Turtles later successfully fended off a MOUSER invasion. After leaving her job with Baxter, April decided to open an antique shop. The shop was subsequently destroyed in a battle between the Turtles and Shredder and the Foot Clan. April and the Turtles retreated to a farm house in Northampton, Massachusetts to recover and during this time she suffered recurrent nightmares about the Foot Clan's attack. During the mid-1990s, April became romantically involved with the violent vigilante Casey Jones, and the two of them eventually raised Shadow, the child of Casey's late wife Gabrielle, as their own. In Volume 2 of the TMNT comics, April was attacked by a huge robot controlled by the brain of her former boss, Baxter Stockman, and injected with nanobots. With the help of the Utroms, the Turtles injected April with turtle versions of nanobots to stop Baxter's plan. The intervention saved April before Baxter's nanobots could reach her brain stem and kill her. The attack rendered April sterile.
