Doomsday is a 3-part story, this part by Nigel Kitching, Richard Elson, Steve White and Tom Frame. The Omni-Viewer has returned to warn Sonic and the Chaotix Crew about the imminent return of Super Sonic. Since Omni isn't powerful enough to take Sonic back to Mobius yet, Sonic has to help Chaotix fight Lightmare and Lord Sidewinder prepares to catch his biggest prize yet.
