Ryan Leslie (also known as Frank Leslie or Ed Leslie) was a Human who served Starfleet as an officer during the 23rd and 24th centuries. In the 2260s decade, Lieutenant Leslie served in the operations division aboard the USS Enterprise. Leslie was cross-trained to perform a variety of duties aboard the Enterprise from helm and navigation duties, to security and engineering.

Early life and Starfleet Academy
Although born off of Earth, Leslie grew up in the city of El Paso, Texas, on Earth, near the Starfleet Impulse Engine Testing Grounds. On clear nights, Leslie would visit the Testing Grounds and wondered if the engines would pass inspection and where they would be ferried off to once they did pass. (TOS novel: Legacy; TOS - Who's Who in Star Trek comic: "Issue 1")
After completing his required education, Leslie enlisted in the space service and began his course of study at Starfleet Academy. Many of his fellow classmates later recalled Leslie as being a "...straightforward, strong young man" and "a nice quiet fellow, who could beat any two men in a fight...". James T. Kirk, who also attended the Academy at the same time as Leslie, recalled him as "the kid who always beat him in judo matches. (TOS comic: "Who's Who in Star Trek 1")
Lieutenant Leslie was assigned to the USS Enterprise at the request of Captain Kirk, who was impressed with Leslie's record in navigational sciences, which led to him being assigned as a relief navigator and helmsman. His advanced skills in navigation also allowed Leslie to take on a second career as a security officer. (TOS comic: "Who's Who in Star Trek 1")
Leslie's first security assignment aboard the Enterprise in 2265 saw him join a surface detail to the automated lithium cracking station on the planet Delta Vega I, where they were ordered to watch over the mutated Lieutenant Commander Gary Mitchell who was contained in a holding cell. (TOS comic: "Who's Who in Star Trek 1"; TOS episode: "Where No Man Has Gone Before")
Leslie later assumed the helm during the subsequent detour to the planet Ravanar IV to investigate the destruction of the USS Bombay, replacing Lee Kelso, who had died during the Delta Vega expedition. He also served at the helm during the Enterprise's departure from Vanguard as the starship headed home to Earth. (VAN novel: Harbinger)
On stardate 1704, Leslie relieved Sulu at the helm following the Enterprise's narrow escape from Psi 2000, and remained at the post as the starship arrived at Tlaoli IV to retrieve a number of survey teams left on the planet's surface. (TOS - The Janus Gate novel: Present Tense)
Leslie was also on the bridge during a mission to investigate the discovery of the sleeper ship SS Botany Bay on stardate 3141.9. During the course of the mission, Khan Noonien Singh and 72 of his "supermen" were rescued from the Botany Bay hulk.
After the reanimation of Khan, Captain Kirk invited Leslie and other members of the crew to an officer's dinner to investigate their guest's origins and motivations. After Khan's identity became known, the genetically engineered superman escaped from quarters and sabotaged the Enterprise engineering control systems, trapping Leslie on the bridge and cutting off that deck's life support. Leslie and the bridge crew lost consciousness from oxygen deprivation.
Khan had Leslie and the unconscious bridge crew brought to the briefing room, where he tried to get them to pledge loyalty to him as the new commanding officer of the Enterprise, making them watch as Joaquin Weiss beat Lieutenant Nyota Uhura, and piped in viewscreen images as another of Khan's supermen slowly suffocated Captain Kirk in sickbay's decompression chamber.
When Marla McGivers helped Kirk escape, Kirk and Spock flooded the briefing room with anesthesia gas, rendering Leslie unconscious, along with the captors. (TOS episode & Star Trek 2 novelization: Space Seed)
Due to his great experience, Leslie was often trusted to command the Enterprise when Captain Kirk and the other senior staff were off the ship. He was in command when the Enterprise encountered Trelane and again when they encountered Lazarus. (TOS episodes: "The Squire of Gothos", "The Alternative Factor")
Leslie was stationed at the engineering console on the bridge during the Enterprise's discovery of the planet Gateway. (TOS episode: "The City on the Edge of Forever"; TOS - Crucible novel: The Fire and the Rose)
Leslie nearly died during a mission to Argus X on stardate 3614, when he was attacked by the dikironium cloud creature. The creature had drained all of Leslie's red blood corpuscles, but Doctor Leonard McCoy was able to save his life, and Leslie made a complete recovery. A short time later Leslie returned to active duty. (TOS episode: "Obsession")
During the Enterprise's mission to the Beta Canzandia III colony, Leslie was instructed to assemble a security team in preparation to take back the colony from Klingon invaders. He then accompanied Captain Kirk to the planet's surface and participated in securing the colony. (TOS novel: Faces of Fire)
On stardate 6720, Leslie served as Lt. Commander Scott's relief at the engineering console on the bridge during the Enterprise's mission to the planet Kyros. When a radiation front moved in on the Enterprise's position, Kirk ordered Leslie and Sulu to tie in their computer banks with the sciences station in the hopes of determining more about the phenomenom. (TOS novel: Spock, Messiah!)
Leslie continued to serve aboard the Enterprise well into the 2270s. In 2277, Leslie (still holding the rank of lieutenant) was serving as the ship's A & A officer. At this time, he attended a banquet that was held in honor of Fleet Admiral Karis Tatenen's arrival aboard the Enterprise. (TOS short story: "The Blaze of Glory") Shortly after, Leslie accompanied Admiral Kirk and a landing party to a lavish banquet put on by Matriarch Miranie on planet Macedon III. (TOS short story: "Under Twin Moons")
By 2308, Leslie had gone on to serve aboard the starship USS Ingersol as well as the space station KR-1, before applying for the post of chief of security aboard USS Excelsior and being accepted. By this time, Leslie had been in Starfleet for over 50 years.
Later in 2308, the Excelsior was destroyed by a trans-universal portal in orbit of Rejarris II. Most of the crew survived the ship's destruction and escaped through the portal to a planet on the other side. First officer Beskle Crajjik was killed when the escape pod he was in crashed, so Captain Hikaru Sulu promoted Commander Leslie to be his first officer. Leslie and the remaining Excelsior crew were rescued 11 years later by the USS Enterprise-B. (TLE novel: One Constant Star)
- The TOS novels: The Fire and the Rose, A Choice of Catastrophes and the TLE novel: One Constant Star give Leslie's first name as Ryan. The TOS comic: "Who's Who in Star Trek 1" gives his first name as Frank, while the novels Present Tense and A Less Perfect Union give his name as Ed.
