I say blue. Withered Freddy just seems boring to me, nothing is very unique about him as there are Withered Bonnie, or Withered Chica. Though I believe the Puppet would be the best choice, because Of her significant placement in the complex lore of Five Nights at Freddy’s, she has unique features that are unlike most in the franchise, and simply just gives off an eerie sensation. But Toy Bonnie also has unique traits, such as his blue colors.
