Carmen Ibañez, born in Buenos Aires as the daughter of a Fleet veteran, enlisted in the Federal Service after high school alongside childhood friend Johnny Rico and classmate Carl Jenkins. Her exceptional mathematical aptitude secured her acceptance into the Fleet Academy, where she trained as a pilot, a career-driven choice that severed her romantic ties to Rico. Assigned to the corvette transport *Rodger Young*, she confronted peril during the Invasion of Planet P when Bug plasma strikes crippled the vessel, necessitating an emergency evacuation. Rescued by Rico’s unit, the ordeal fortified her resolve, propelling her promotion to captain and command of the starship *John A. Warden*. During a mission to asteroid outpost Fort Casey, her ship was seized by Carl Jenkins, now a senior Paranormal Warfare official, triggering a crisis as an Arachnid Queen hijacked the *Warden*’s systems to target Earth. Collaborating with Major Henry “Hero” Varro’s team, she strategized to neutralize the Queen, diverting the ship’s crash trajectory to the Alps to spare Paris. Her leadership included enforcing evacuations, challenging Jenkins’s unethical methods, and navigating tensions rooted in their shared past, all while maintaining protocol and mission focus. Known for analytical precision, adaptability under pressure, and unwavering duty, Carmen evolved from initial training hesitations to steely composure in combat. Her career exemplified the Federation’s ethos of collective sacrifice, prioritizing service and citizenship. While her post-crisis fate remains unrecorded, her legacy endures through decisive leadership during existential threats and pivotal military operations.
