This is Keith's oldest, bitchy and highly authoritative sister, Heat.
Or "Fawxheat", her stage name.

Her true name is 'Dorsey' (she is somewhat bothered by it), but she gained the nick name "Heat" due to the fact she thrives on causing lots of it in people lives- never in a good way!

Janet Fawx was designed first, Heat came later in 1989. Which at first was red with brown markings (instead of Keith's black), with white markings. This image above is an outdated image, as she is less 'beastly' in the face, as is Janet (smaller muzzles). Only Keith retained his beastly toothy wolf/fox appearance.

In my story I revealed she was Gage's bridge into the Royalty's heavily guarded private life, learning all their security clearances and such. Heat at one time dated Gage, being the 'can't keep a secret' type of person, Heat told him everything he wanted to know. Gage had her strung out over him, though she would never admit to it.

Gage being Gage, used the information given to him by Heat, against the Royalty. It made them appear as foolish incompetent leaders of the galaxy, publicly embarrassing them, stealing their starships and other humiliating situations to name a few.
