Firefly is a former Iron Cavalry Knight and current member of the Stellaron Hunters. She is a synthetic human grappling with her fate while yearning for emotional intimacy. She contrasts between her sweet, kind self and the cold, pragmatic persona of SAM when in her Powered Armor. Firefly's quest for life, identity and purpose, drives her to seek companionship and emotional and physical intimacy, hoping to defy her genetic fate and find meaning beyond the battlefield, and forget her tragic past.
