I've made customs of the Post Super Genesis Wave freedom fighters before, and in 4 inch scale I've made Sally and Bunnie so far, but this is the first time I've made this version of Rotor in this scale. He started life as a 5 inch movie Knuckles figure with the Rotor parts 3D printed from the official models used for cover art in the Archie comic.
