On one occasion, the Eleventh Doctor recalled memories of his fourth incarnation meeting up with Kirk and the command crew of the USS Enterprise to combat a CyberNomad invasion of Aprilia III. After Kirk had informed the Doctor that his communicator had a gold cover, he distracted the Cybermen until the Fourth Doctor used the gold to disable them. While the Doctor took his leave, Kirk checked on the staff, blissfully unaware that Cyberman coding still existed in the facility's systems. Following the Eleventh Doctor and the Enterprise-D defeating the cyber-web, the Doctor suspected that his encounter with Kirk had been erased from the timelines. (COMIC: Assimilation²)
Spock's Brain was an episode of Star Trek which both Izzy Sinclair and Destrii had seen. Destrii even went so far as to call it her "favourite." She cited "the bit where Sulu has to do the captain's log" as a particularly memorable moment and even quoted back a portion of the log, in unison with Izzy: "Captain Kirk's hunch that Spock's brain is on this planet appears to be correct!" (COMIC: Ophidius)
When Clyde Langer and Luke Smith were on Kudlak's ship Luke asked Clyde if he could use his mobile phone to which Clyde sarcastically asked if he had a phone number for Captain Kirk. Luke was unfamiliar with the character. (TV: Warriors of Kudlak)
When DI Patricia Menzies entered the Sixth Doctor's TARDIS and saw its console room in 2010, she commented that she had expected the TARDIS interior to resemble "Captain Kirk's ship". The Doctor responded, "Detective Inspector, may I tell you something and I can't stress this enough: I am not Captain Kirk." (AUDIO: The Crimes of Thomas Brewster)
Behind the scenes
The mentions of Captain Kirk in The Gallifrey Chronicles, Ophidius and The Crimes of Thomas Brewster treat him as a fictional character (as do, implicitly, other references to Star Trek and Star Trek: The Next Generation in Doctor Who stories). Assimilation², of course, treats him as a "real" individual. It also shows that he exists only in another universe. It is thus possible that he is a character in the Doctor Who universe but a real man in the Star Trek universe.
