Newly uncovered Sonic the Hedgehog (SatAM) concept art gives us an early look at a robotic Dr. Robotnik

Way back in 1991, when Sonic the Hedgehog burst onto the scene in his debut game, the title made such an impact in the west that TV networks and animation studios scrambled to create an animated series starring the blue blur. With Sonic came his cast of video game co-stars however at the time Sonic’s stable of characters was quite small. Outside of the little animal friends and badniks, we had Sonic, Eggman (localized as Doctor Robotnik) and eventually, in 1992, Tails. The first animated series to get the green light was what fans affectionately call “Sonic SatAM” or just “SatAM” as the series aired weekly on ABC Saturday mornings. This series retained Sonic, Tails and Robotnik, but also expanded the cast to include the Freedom Fighters as well as a lackey for Robotnik named Snively.
