Fiona Fox

Name speaks for itself. To be honest I never liked this character. Not saying she isn't a good design she's actually a much better character design than what Sega or the Sonic Team can produce but I never liked that Tails had a crush on her, that Sonic dated her, that she turned to Scourge. She was damn near a whore in the comics but she has a good past, and makes a good villain for any character and to be honest, I would like her to be a main rival for Blaze the Cat mainly cuz they're more alike than most people realize but just have opposite moral values and histories which of course, pins them on opposite sides.
