Their first mission involves tracking down the failed Hulk-copy experiment Private Benjamin Tibbits (AKA Flux) and killing him.

After failing to defeat the Hulk, the Gamma Corps discover that he was not directly responsible for their individual situations, so they pursue the people who were, the Illuminati.

Without the backing of the US government, the Gamma Corps become fugitives in hiding, but they continue to search for each Illuminati member.

[2] Some time later, Ryker (under the auspices of Norman Osborn) creates a second Gamma Corps, composed of female "volunteers" (mentally unstable ex-soldiers on death row) for the Origins Corporation's gene therapy program and sends them to capture the new She-Hulk so that her DNA can be harvested.

[4] The remaining two flee to a small town, attempting to hold the people hostage in order to make Lyra surrender.

[5] In the ensuing battle, Lyra badly wounds Aberration, causing her body to mutate into a tumorous mess, before finally killing her with a pipe to the head.
