Krakowski was a 23rd century Human man. He served in Starfleet's security division in the 2260s decade, at the Federation starbase on Tau Delta IX.
History[]
In the year 2268, Krakowski discovered two officers unconscious in the starbase's communications section, and then arrested someone who had been tampering with the computer systems. The intruder, who looked like Captain James T. Kirk, was actually Harry Mudd. (TOS - New Visions comic: "Made Out of Mudd")
