Alternate timelines and realities[]
Provenance of Shadows[]
After traveling through the Guardian of Forever in 2267 to New York City in March 1930, McCoy saved Edith Keeler's life, an act which, unbeknownst to him, altered Earth history. McCoy spent two years in New York, expecting his colleagues to follow him back in time and rescue him. He placed numerous classified ads directed at Kirk and Spock in the hope that these newspaper records would survive into the 23rd century. By June 1932, however, he had become resigned to the fact that rescue was not coming, and he left New York and the Twenty-First Street Mission to re-establish a life for himself.
With little money, he jumped a southbound freight train, heading for his native Atlanta. On the way, McCoy was accosted by two other vagabonds, forcing him to jump from a moving train. He found himself in Hayden, South Carolina, badly injured and in need of medical attention. He encountered local resident Lynn Dickinson, who took him in and called on Doctor William Lyles to treat his injuries. Lynn and her husband, Phil, put McCoy up during his convalesce, and continued to board him for several weeks after, claiming McCoy as Phil's second cousin.
In November 1932, McCoy was compelled to perform an emergency tracheotomy, revealing himself to be a physician. Lyles, who had been initially suspicious of McCoy, offered him a partnership in his practice. When Lyles died of a heart attack in September 1934, McCoy took on his home and office and became Hayden's sole doctor.
In 1937, a rift formed between McCoy and Phil Dickinson after the doctor acted to defend an African-American man named Benny Russell from racist attackers. The incident also prompted Lynn to reconsider her own prejudices, and elevate her regard for McCoy.
McCoy was surprised when December 7, 1941, passed without news of the bombing of Pearl Harbor. He realized then that, because Edith Keeler had survived her brush with death years earlier, was able to become a powerful voice in the American Pacifist Movement and exert significant influence on the Roosevelt Administration, so much so as to delay or prevent the United States entry into World War II. McCoy confronted Keeler during a rally in Atlanta in late 1941, but was unable to sway her from her anti-war stance.
By 1944, after London had fallen to the Nazis and Japan had conquered Australia and New Zealand, the Axis finally struck against the United States in Hawaii and drew the nation into war. Phil Dickinson enlisted in the Army, and was killed in action in Ireland in May 1946.
McCoy and Lynn grew closer in the years that followed, though McCoy insisted on keeping the relationship platonic. However, when the Nazis dropped an atomic weapon on Atlanta in 1954, at the same time Lynn was supposedly in the city, McCoy was moved to propose marriage.
In 1955, a Nazi fighter was shot down over Hayden and crashed on the edge of town. McCoy, while attempting to offer aid to the pilot, was stabbed and killed. (TOS - Crucible novel: Provenance of Shadows)
A Less Perfect Union[]
In a timeline in which John Frederick Paxton destroyed Starfleet Command and ended the talks for the Coalition of Planets in 2155, McCoy became a widower upon the death of his wife Jocelyn in 2246, only a month after the birth of their daughter Joanna.
Consequently, he raised Joanna single-handedly and the two developed an extremely close relationship. In 2264, shortly after Joanna began studying medicine at the University of Mississippi, McCoy embarked on a career in the United Earth Starfleet. He was assigned as the chief medical officer of the UESS Enterprise under the command of Captain Christopher Pike following the retirement of his predecessor Phillip Boyce.
He assumed that position immediately before the Enterprise's mission to transport Lady T'Pol and Ambassadors Nancy Hedford and Garrett Tarses to Babel, where they were to petition the Interstellar Coalition for United Earth's admission into the organization. Unlike many Enterprise crewmembers including its first officer Commander James T. Kirk, McCoy approved of the mission.
After being easily defeated by Kirk in a game of chess in the Enterprise mess hall, McCoy casually suggested that T'Pol, the Vulcan former first officer and last surviving crewmember of the Enterprise (NX-01), would be able to provide Kirk with a challenge. In response to this comment, Kirk made his xenophobic attitudes towards the Vulcan abundantly clear, as did Lieutenant John Stiles. McCoy told them that he and his ancestors going back more than 20 generations were from Georgia, where Martin Luther King, Jr. had begun his career as a civil rights campaigner more than 300 years earlier. He argued that expressing bigotry for others based on their species was no different from harboring such feelings for other humans based on their skin color. As he left the mess hall in disgust, McCoy could see that he had made Kirk furious but believed that he may have at least given him food for thought. This assessment was later proven correct.
While treating the injured Captain Pike in sickbay several days later, McCoy once again exhibited his tendency to be extremely plainspoken with his superior officers. Although Pike had never refused a request from one of his officers to speak freely, he appreciated being asked. However, McCoy's candidness reminded him of Boyce and, before returning to the bridge, Pike expressed his hope that McCoy would likewise become one of his closest confidants.

The Tears of Eridanus[]
In an alternate timeline in which the Vulcans had remained a violent and emotional species, McCoy served as the chief medical officer of the IUES Enterprise I, a Charter-class starship of the Interstellar Guard in service during the late 23rd century. He was succeeded by Jabilo M'Benga. (ST - Myriad Universes novel: The Tears of Eridanus)
Andorian McCoy[]
In one alternate permutation of the Kelvin timeline, McCoy was an Andorian Starfleet officer. He served alongside a Vulcan Hikaru Sulu and a Cheronian Montgomery Scott. They experienced the chronotronic event in 2262. (TOS - Boldly Go - IDIC comic: "Part 5")
