Erika Hernandez was a Starfleet officer who served during the mid-22nd century. By 2154, she has risen to the rank of captain and commanding officer of Earth's second warp five starship, Columbia NX-02.
Before her promotion to the rank of captain, Hernandez was romantically involved with fellow Starfleet officer Jonathan Archer. However, when Archer was promoted, becoming Hernandez's superior officer, he broke off their relationship. (ENT: "Home")
Hernandez's last assignment prior to taking command of Columbia was on the Republic, under Captain Jennings. When she left the ship, Jennings told her that she could have anything that she wanted. Hernandez ultimately chose to take his chef. (ENT: "Affliction")
Hernandez was promoted to captain in 2154. She was then assigned, along with several other officers, to audit Archer's debriefing subsequent to the Enterprise NX-01's return from the Delphic Expanse. After Archer was ordered to take some time off by Admiral Forrest, Hernandez joined Archer as he went rock climbing.
Although Archer was initially reluctant to accept Hernandez's company, as he viewed her as an uncomfortable reminder of the personal sacrifices he had made during his mission to save Earth from the Xindi, Hernandez was successful in assisting Archer in reconnecting with his Humanity, and briefly rekindled their intimate relationship. (ENT: "Home")
Although Columbia was initially scheduled to launch in June of 2154, engine difficulties prevented the ship's departure from spacedock until November of that year. During that time, Hernandez twice unsuccessfully attempted to recruit Commander Charles Tucker, chief engineer of Enterprise, to her crew. Ultimately, Tucker chose to accept the transfer for personal reasons, and was able to accomplish modifications allowing Columbia to launch.
Shortly afterwards, Hernandez was contacted by Captain Archer, who was requesting Tucker's assistance in repairing Enterprise's warp drive, which had been sabotaged by Klingons. After the successful repairs to Enterprise's engines, Hernandez and her crew joined Enterprise in a dangerous mission into Klingon space to rescue their chief medical officer, Doctor Phlox, and in resolving a crisis involving a virus spreading throughout the Klingon Empire. After the resolution of the crisis, Hernandez granted Archer's request to keep Tucker aboard Enterprise to assist with repairs. Eventually, Tucker asked Hernandez for a permanent transfer back to Enterprise, a request which Hernandez granted. (ENT: "The Expanse", "United", "The Aenar", "Affliction", "Divergence", "Bound")
Hernandez' first name comes from the script, and is not used in any episode. Indeed, in her first appearance in "Home", she is not named at all.
The script for "Home" describes Hernandez as being in her "late thirties", which would put her birth year at some point during the late-2110s. It goes onto describe her as being, "of slight build and carries herself with an air of confidence." (citation needed • edit)
The reference book Star Trek: Federation - The First 150 Years states Hernandez was promoted to fleet captain prior to the start of the Earth-Romulan War, and in 2156, Columbia and Excalibur were ordered to Starbase 1 in the Algeron system, officially for scheduled maintenance, though the real reason was to protect the base from a potential Romulan attack. The Romulans had declared that Algeron was their property and ordered Humans to leave weeks before. On May 18, five Romulan warbirds attacked the system and jammed communication channels. Hernandez ordered the Excalibur to retreat and warn Starfleet, while Columbia stayed to defend the system. Columbia was lost with all hands, including Hernandez.
Hernandez appears in the Star Trek: Enterprise novel Beneath the Raptor's Wing, during which her ship is attacked and incapacitated by Romulan forces, requiring a tow home from Vulcan ships. She is later present at a Coalition Security Council meeting during which Soval announces Vulcan's alternative defense plan. Hernandez finds this plan to be ridiculous and questions it. Later, she has dinner with multiple starship captains at the Lotus Blossom. The novel takes place in the year 2155.
In the Star Trek: Destiny novel Gods of Night, the Columbia is assigned to escort a convoy when they are attacked by the Romulans, in the year 2156. With the convoy destroyed and the Columbia's warp drive offline, Hernandez orders the use of the ship's impulse engines to make a journey to reach the nearest class M planet with any sign of technology, during which the vessel and all aboard experience time dilation effects. While the journey takes twelve years in normal time, the crew of the Columbia experience a passage of only sixty-three days. Arriving in 2168, Hernandez commands the landing party to the planet Erigol that makes first contact with the Caeliar race, liasioning with Inyx. After efforts by Major Stephen Foyle and other members of the team to use the Caeliar's technology to return the Columbia to its original time go badly wrong, the city-ship of Axion, including Hernandez and three of her crew, are relocated in time to the year 1519.
This story is followed up in the Destiny novels Mere Mortals, in which Hernandez encounters Captain William Riker and the USS Titan in the year 2381, and Lost Souls, in which she meets the crew of the USS Enterprise and reveals her true nature as a Caeliar.
