Sonic Universe - The Silver Age

Issues #79–82 comprise 'The Silver Age', which follows Silver as he confronts the threat of the Genesis Portals. Helping him on his mission are scientist Professor Von Schlemmer (a character from Adventures of Sonic the Hedgehog) and Gold the Tenrec; opposing them is the evil Onyx City Council and their force of Civil Protection Robots. The events of this arc are set prior to the 'Worlds Unite' crossover, despite the issues forming it being released afterward.
