Harrison Murdock

Harrison wears her dark brown hair long and looks out through brown eyes. She dresses in the regulation gear issued to members of the Callisto Liberation Front.

Like her brothers, Harrison can come across as clumsy and inept, yet she clearly outstrips both of them in wit. Where her siblings simply follow orders, she is quick enough to think for herself and willing to push back against her domineering mother.

As part of a campaign to halt Kao Construction's terraforming of Callisto, Harrison joined her brothers Ron and Derek in seizing an opera house where the firm's CEO, Loren Cadena, was attending. After grabbing Cadena and a second captive, Mark Manly, the siblings triggered a holographic broadcast of their mother, who branded the group the Callisto Liberation Front and berated Cadena for the harm her company had done. The plan to threaten Cadena with a spore grenade collapsed when Mark knocked the device loose, activating it, mutating Cadena and turning other patrons into trees. Left without a hostage, the siblings fled aboard a ship they stole from Faye.

Back at base, their mother scolded them for Cadena's death and singled Harrison out, ordering her to become as shrewd and merciless as herself. When Mark's phone rang, it emerged he had been dragged along as a hostage. Maria announced she had located the missiles she needed and that the children's father held them, so the family set out for Ganymede, though not before Harrison finished off Mark and stripped Faye's ship of anything valuable.

Once Jet, Spike, and Faye tracked the front to the Kao Construction site, Maria ordered Ron and Derek to ready the missiles while she and Harrison prepared their escape ship. Faye ambushed the pair, but Harrison broke free and fled with her mother aboard. Jet and Spike knocked out the brothers and stopped the launch, and when Maria fired the missiles remotely, Faye destroyed them. Rather than face a lifetime in prison alongside her mother, Harrison embraced Maria's lesson about being smart and ruthless, using a spore grenade to turn them both into trees.
