The first 2 RP Story things will be during the whole war on Earth. In here, any OC can fight AXOMs army and fight off his empire as a plan is made to defeat AXOM fully.
However, the 3rd RP Story is much more different. Robotic/A.I. based OCs are needed for this plan, which they will enter AXOMs digital scape and try to get to his Matrix to destroy it so he will be deleted entirely.
In the final actual story, these charaters would finally get to the matrix after a intense fight with its Guardian. However, they will be given a choice thats presented in the Matrixs code. First option is to delete the Matrix, hence killing AXOM and stopping his entire invasion fully. Or second option, full system reboot. This reboot will revert AXOM to as if he was just created, all of his memories, ideals, and overall control over his empire will be gone. With this, his invasion will stop and he can "molded" to something else.
