The beautiful, maturing woman on the planet Attila assumes the role of mother to her younger siblings, necessitated by her mother's death at Cylon hands. When not caring for the younger children or keeping elder brother Kyle under control, she fights the "tin cans" fairly often, riding on unicorn-like creatures. When Starbuck crash-lands on the planet, she and her siblings manage to liberate and take care of the injured Warrior.
Miri takes an interest in the Warrior; however, her hopes are shattered by the spiteful Kyle, who forces her to place a note in the Cylon-occupied castle arranging an exchange of the Warrior for her father. Starbuck, with some assistance from the love-struck Miri, manage to convince Kyle otherwise.
They quickly plan an assault on the castle as well as an escape plan to get Megan out of Cylon hands. Miri and Starbuck manage to liberate her father from Specter, the devious IL-series commander, and eventually defeat the Cylons themselves.
