Star Trek" & reg: Revisitations is an omnibus edition that combines two multiple-issue stories from the DC Comics "Star Trek" series, both of which feature the return of popular supporting characters from the original TV show. In the first, Harcourt Fenton ("Harry") Mudd runs afoul of the zealously religious alien Nasgul, and only Captain Kirk can rescue him from their vengeance and prevent a declaration of interplanetary war. In the second, the enigmatic Gary Seven turns up to warn Kirk and Spock against testing the Federation's new protomatter weapon, and when they press him for more details about his sources of information, Gary Seven's secrets revealed at last.
