Sonic the Hedgehog (Archie Comics series)

Sonic the Hedgehog is an ongoing comic book series published by Archie Comics, based on the Sega video game franchise and featuring the character of the same name, since May of 1993. The series has had many spinoffs, including the still ongoing Sonic Universe which began in February of 2009.

Both comics had a crossover with Mega Man in the storyline Worlds Collide from April to August of 2013.

Whereas Worlds Collide has had no lasting impact for the Mega Man comic, the issues of Sonic the Hedgehog, following the crossover are dealing with the repercussions (due to Dr. Eggman interfering with Sonic's attempt to restore their world), as well as Sonic Universe containing a follow up.
