Robofox

This is Tails in the form of a Badnik. The original Robofox construct was similar to a cyborg in that Tails was not encased in a suit of Metal like other Badniks; the Metal was attached to him. Brainwashed by Robotnik, Tails attacked Sonic but managed to resist and break free of Robotnik’s control to save Sonic from being squashed. The second Robofox suit was a traditional Badnik case, however Robotnik was never able to trap Tails in it.
