Roberta "Bobbie" Draper

Bobbie Draper is a Martian Marine gunnery sergeant, a career soldier who believes without irony in duty, discipline, and the Martian project. She leads from the front, trusts her squad completely, and carries herself with the unshowy confidence of someone who has trained her whole life for exactly this kind of fight.

Frankie Adams plays her as a body first — the show lets her move like an actual heavy-worlder soldier, all coiled weight and trained economy, before it lets her speak. That physical authority makes her later disorientation land harder: a woman built entirely for certainty, dropped into a world that keeps refusing to hold still.
