Dr. Ivo Robotnik, often known simply as Dr. Robotnik, is of course the most well known of Sonic's many opponents and while the videogame adversary is well known their exists some alternate versions of the mad scientist that are not quite as well known. Such is the case of the Robotnik found within the pages of the now discontinued Sonic the Comic, which was published by Fleetway as the main Sega-based comic in the UK.
