Callie Briggs is the Deputy Mayor of Megakat City and is often the one running it while Mayor Manx is teeing off for another round of golf. She is highly independent, and has proved on more than one occasion that she is quite capable of taking care of herself during a crisis. She is a friend to the SWAT Kats, and alerts them of any trouble happening within the city that they should be aware of.
Calico “Callie” Briggs (voiced by Tress MacNeille) – Deputy Mayor of Megakat City and the one who does the real work of City Hall. The SWAT Kats’ biggest supporter, she has a radio communicator which enables her to call them directly when danger threatens the city. Although she does not know who they are, Callie usually trusts her life to the SWAT Kats if required. In The Dark Side of the SWAT Kats, in a parallel universe she is an evil ally of Dark Kat; in Bride of the Pastmaster her ancestor was Queen of the medieval kingdom of “Megalith City”. Though T-Bone has a crush on her, she has a crush on Razor (more evident in the fact that even her ancestor seemed to favor Razor over T-Bone), likewise, she also seems to favor Jake. Her name is a pun on Calico cat breed.
