After beating Bunnie Rabbot and Knuckles the Echidna, Mecha Sonic proceeds in destroying Knothole Village. Believing Sonic to be a traitor, Sally orders Rotor to bring in the Roboticizer that was used to roboticize part of Bunnie's body. Knuckles awakes in a daze and attacks his friends, thinking that they are enemies. Sally snaps Knuckles out of his dizzy state by kicking him from behind. Sally explains their need for drastic measures and hands him a Neuro-Overrider to let him keep his free will. Now in a stable mind, Knuckles agrees to be roboticized and jumps in the roboticizer.
