Zingo is the pet female dog of the Mutant Underground.
In Threat of Extinction, Blink came down the stairs to the sight of Norah petting Zingo. Clarice claimed that the dog was pretty particular about the people she liked, Clarice and Norah were lucky enough to be two of them, which Clarice stated was due to the fact that they were special. Most of the mutants walking around the station were unidentifiable from humans, unlike them, as Clarice had pointed ears and green eyes while Norah had blue skin, and Zingo had fur.
Zingo has black and white fur with black spots. She has bright blue eyes.
