While not a genius on Peter Parker's level (despite her protests), Greer is quite intelligent and got an internship with Dr. Rumulo and helped her develop her Cat Suit and Super Soldier recreation. Acting as a guinea pig for her mentor Greer volunteered for the Super Soldier Serum remake but alas the recreation was not as efficient as the original requiring the addition of a enhancement suit, the Catsuit.
As the project neared completion Hydra attacked the lab, kidnapped Dr. Tumulo, took a suit and destroyed the lab, presuming Greer dead and buried under the rubble. But Greer survived, repaired and patched together the remains of the destroyed suits and started out on a quest to rescue her mentor.
Invading Hydra Base Greer discovers several other heroes are with her along with a lot more kidnapped scientist all being held under duress, Norman Osborn, Curt Conners, Tumulo, being ordered around by Dr. Morbius and Dr. Otto Octavious. With the help of the other heroes as well as a semi sane Lizard (Curt Conners) they are able to get everyone out but not before having to face a trio of Hydra Experiments from all th scientists they kidnapped. Catseye, a shape-shifting mutant, White tiger, using a suit like hers, and Spidercide, a genetically enhanced shape-shifter with spider powers. But they stop them, and Shield takes them into Custody along with giving the scientists protection aboard the Helicarrier so Hydra can’t get to them again.
Greer considers her better then most of here peers, shes confident, sassy, and smart.
