Sonic Universe

Sonic Universe is a spin-off Sonic the Hedgehog comic book series published by Archie Comics. Set in the Sonic the Hedgehog continuity, Sonic Universe is designed to expand the horizon of that fictional universe. The series deals with various characters throughout the fictional universe, particularly those that are less prominent in the main series, including Shadow the Hedgehog, Knuckles the Echidna and many more.

Sonic Universe is published monthly by Archie Comics alongside its parent title Sonic the Hedgehog, and the two frequently tie-in together. The first issue was released to comic book stores on 25 February 2009 and fills the role of the "second monthly Sonic comic" following the cancellation of the Sonic X comic series.
