Robert Callahan
From FEInfobase
Captain Robert Callahan is the Commanding Officer of the USS Perseus NCC-78386, and a native of the colony of Taurus VI. Born in 2365 to young parents Logan Callahan and Annie Driscoll, most of Robert's early years were spent on Earth, as his father attended the Academy. However, his parents had been brought together more of a matter of his mother's pregnancy than any true love between them, and before even Logan's graduation Annie had returned to Taurus with Robert, their relationship over.
Callahan was thus brought up in a typical Taurusian manner, in a culture valuing self-sufficiency and hardiness of body and spirit. His father's distant yet strong presence in his life encouraged Robert to join Starfleet when he was of age, which was just at the beginning of the Borg Conflict. As such, the entirety of Callahan's career has been spent thus far in the Borg Wars, and he was assigned to the USS Thunderchild for ten years before being made her Executive Officer in 2397. He served in this capacity until the Battle of Sol, where the captain died and Callahan assumed command.
He commanded the USS Thunderchild until 2403, when he was promoted to Captain and transferred to the USS Perseus. He now serves as one of the most prominent COs in the Earth Defence Force.
