Fiction
The Headmasters cartoon
- Voice actor: Kazumi Tanaka, John Culkin (English, Omni Productions dub)

When Scorponok's Decepticons returned to planet Master, Kirk served as the leader of the resistance group that formed to oust them. They met with little success, until the Autobot Headmasters arrived on the planet in pursuit of the Decepticons. Chromedome arranged a meeting with Kirk to formulate a new plan, intending to corral the Decepticons amidst the cloudy peaks of a nearby mountain range. The plan was put into motion when the villains attacked a city, but backfired when the clouds did nothing but provide the Decepticons with cover, which only increased their advantage. During the firefight, Kirk's fighter craft was shot down and Chromedome believed him dead; when the battle was concluded with a Decepticon victory, Kirk hauled himself from the wreckage of his craft. Chromedome apologised for the recklessness of his plan, but Kirk admitted that he was to blame too for willingly going along with it. Operation: Destroy the Decepticons
TV Magazine Masterforce prologue
Some time later, after the Decepticons had been forced off of Earth and a larger war began based around use of advanced technology from Planet Master, Chromedome and the other Headmasters took it upon themselves to train Kirk and the other Master Warriors in the use of their powers.

Toys
The Headmasters

- Kirk (Cybertron Master Warrior, 1987)
- Available exclusively in Japan in a tiny individual box, Kirk transforms from a grey and red humanoid robot into a humanoid head, in which mode he can connect to any of the larger Headmaster toys, activating their built-in Tech Specs meter. Kirk grants his host body a Speed rating of 8, Strength of 10, and Intelligence of 6. Kirk and his fellow Autobot Master Warriors go for ludicrous sums of money on the secondary market.
- What go for even more ludicrous sums of money are the super-rare, entirely white versions of the figures. These were only available as part of the "Throttlebot Promotional Sales Campaign", where a bagged all-white Headmaster was given away with the purchase of any Throttlebot at select Japanese retailers (sadly, we do not know which retailers these were).
Notes

- For whatever reason, Kirk's cartoon color model is completely different from his toy, decorated with green, blue, yellow, grey and white, where the toy was grey and red.
- Speaking of color changes, the original catalog photos of Kirk show him with orange limbs, matching his face paint.
