James T. Kirk/Time travel

Several of Kirk's voyages involved travel through time, either personally through time portals or along with the entire starship Enterprise via acceleration through gravity wells. According to the Federation's Department of Temporal Investigations, Kirk, who sometimes ignored regulations when he felt it was for the greater good, amassed seventeen separate temporal violations during his career, more than any other person on file as of 2373.
His time-travel exploits were well-known enough that, when Sisko, after he and his crew returned to the 24th century, told Dulmur and Lucsly that the vessel they had encountered in the past was the first Enterprise, the two DTI investigators shrugged at the realization that it was "his" ship, which Sisko proudly confirmed. Kirk was regarded by DTI as a "menace". ()
