Ambushing Lyra during an intimate moment with her partner, Axon violently brought down the flying ship carrying her prey. Momentarily stunned, Lyra watched helplessly as Axon drained the life from her partner, leaving him a charred husk. Lyra declared she would avenge his death, but Axon and her teammates, Aberration and Morass, didn't appear too concerned – at least, not until Lyra escaped and viciously beat Morass, possibly to death.

Axon fled with Aberration, but Lyra gave chase – draining them of their strength, so she could finish them off with relative ease. Axon desperately needed to feed to restore her energy reserves, and even fed off an unwilling Aberration until a more tempting target was found. An unsuspecting town with numerous civilians served as her dinner plate, and after killing several humans, Axon contacted General Ryker. She requested transportation and advised their mission was compromised by witnesses, but Ryker reminded her that there were to be no witnesses. Axon forced the townsfolk out of their homes, allowing Aberration to take them hostage. Unfortunately, a furious Lyra emerged on the battlefield and threatened to kill Axon and Aberration despite the innocent lives they threatened.

Axon, before she was given power by General Ryker, was not mentally fit to be trusted around others since her return from an operation in Symkaria where she was the sole survivor. At Fort Leigh, military police were dispatched to a complaint of fighting at her residence. Believing the police were the same insurgents that slaughtered her unit, Erin Cicero gunned down three officers. Once she was in custody, it was discovered Cicero had killed her entire family, also believing they were the enemy. Standing idly by as Lyra murdered Aberration, Axon made her final stance when she threatened to kill every person in town unless Lyra allowed her to absorb her mind and Gamma Sight without protest.
