Archie Comics

Archie Comics is an American comic book publisher known for publishing original comic adaptations of the Sonic the Hedgehog television series, Knuckles the Echidna, Sonic X, and an original title called Sonic Universe. All the comics are officially sponsored by Sega and are ongoing. Currently, Sonic the Hedgehog and Sonic Universe are still running, but Knuckles the Echidna and Sonic X have ended.

Archie Comics carried the Comics Code Authority (CCA) seal; however, it was removed in February 2011 in favor of self-regulation of content.

In May 2011, Archie released the first issue of Mega Man, based on the Capcom games and featuring the character of the same name. From April to August 2013, Mega Man #24-27 crossed over with both Sonic the Hedgehog and Sonic Universe in a twelve issue storyline Sonic & Mega Man: Worlds Collide.

Sonic X
From 2005, Archie Comics began a comic series based on the anime series Sonic X. While the series is set in the timeline of Sonic X, their plots are original. In response to the fan letters, the writers have stated that the comic series takes place between the second and third seasons (so after the Sonic Adventure and Sonic Adventure 2 adaptations, but before the gang returns to their unnamed homeworld). The series had a total of 40 issues. The last issue notably featured a crossover with the regular Sonic the Hedgehog series involvingShadow and Metal Sonic from that universe that transitions to Sonic Universe.

Many other characters have had cameo appearances, including Cosmo who never appeared until around the time Season 3 of Sonic X was announced.
