*Payback Fox, formerly known as Fiona Fox, is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. She was the alternate version of Fiona Fox from Dark Mobius and a member of the dwindling resistance opposing Enerjak.

Payback is a red and yellow fox with blue eyes and light brown hair. Being an alternate-universe counterpart, Payback is very similar in appearance to Fiona Fox. However, there are a few notable differences. Being older, she has some lines around her eyes. Payback's dull hair is worn in a rough ponytail; she wears a torn blue top, brown shorts with a belt, brown boots with greaves, metal shoulder-pads and a beaded necklace. Her hands had been roboticized by Sir Charles Hedgehog's Roboticizer, perhaps to save them from a grievous injury.

Payback Fox's roboticized hands have been modified to absorb and throw back energy projectiles, hence her name.*
