In the mirror universe, Lieutenant Kisho Akamatsu was a Terran officer who served in the Imperial Starfleet.
Akamatsu served aboard the ISS Indomitable as a science officer and was responsible for telling Captain Erin Stone of the status of a battle between the ISS Constellation and four Klingon warships. Akamatsu was later killed when the Indomitable joined the battle alongside the Constellation. (Mirror Universe short story: "Ill Winds")
- It is unknown whether or not Akamatsu has a counterpart in the primary universe.
