Renfield then trapped Sonic and the Freedom Fighters in a House of Mirrors (within the mirrors themselves). Knuckles managed to escape and later met up with the rest of the Chaotix, including Heavy and Bomb. Turns out that Dr. Robotnik had made a deal with Renfield and worked together with him to trap the Freedom Fighters. Knuckles and the Chaotix liberated Sonic and the others, and making short work of Robotnik's new Metal Sonic robot. Robotnik ditched Renfield and allowed him to be captured by Knuckles. Later on, Renfield reopened his amusement park to the public.
