Mayor Manx is the great-grandson of famed war hero The Blue Manx and Megakat City's longstanding mayor. He has been in office for a total of 11 terms far. His voice suggest either Irish or Scottish decent as it is a thick accent.
Mayor Manx is an individual with black eyes. Manx frequently wears a suit with a green jacket, black vest, and red tie. He has whiskers on the sides of his face. He also sports circular eye glasses and is revealed to be bald as he wears a wig.
Whilst not wicked, neither can he be said to be "good". His regard for his city and its citizens is primarily directed as to how it affects himself. He is conspicuously fearful, opportunistic, amateurish, feeble, and to a degree rather work-shy, but in his own way is a consummate politician. Whilst not a particularly virtuous individual, in most situations he is able to direct the public view to a more positive light during a crisis, although many times his assurances are almost instantly proved to be premature. He has a habit of leaving the real work of his office to Callie Briggs, the deputy mayor. A huge golfing enthusiast, he is frequently seen both in his office and outside playing golf, even during a crisis, and a long running gag in the show is of his games being thrown off by the SWAT Kats battling a villain in the proximity.
- Few fans rightfully think that Manx shouldn't be mayor of MegaKat city.
- In "Enter the MadKat" When MadKat capture 4 certain people in his box, he picks out Manx as the King from his past.
- He was voiced by Jim Cummings (Season 1-2).
