This marks the first time a graphic novel title has been released with a variant cover.
The main cover comprises art from SU#54 (Sonic and Mega Man themselves) and MM#24 (the background), while the variant takes its art from StH#248 (Sonic and Mega Man) and StH#251 (the background).
Sonic's prologue consists of the final two pages of SU#50, plus three pages made entirely of material from other issues.
The first is a full page shot of Eggman pondering, telling somebody to ready the interdimensional portal, and that "Albert better be ready" (said dialogue lifted from StH#247). Eggmans artwork comes from page twelve of StH#257.
The second shows Sonic and Tails watching in bewilderment as everything around them fades to white: Sonic utters his line from the end of #247, "Oh no, this is-". The (slightly altered) poses are lifted from page eight of StH#252.
The third page depicts Sonic and Mega Man both being blinded by a flash of light (representing the Genesis Wave). Both poses are lifted from MM#25: Sonic's from page three, and Mega Man's from page eleven.
The titles of both the prologue and epilogue stories are not actually used in the book: the titles are listed above for clarity.
Early listings for the book were initially very different from the final product: originally, two versions of the book were planned to be released, alternately titled "Worlds Collide: Deluxe Edition" and "Worlds Collide: Super Deluxe Edition", with it being implied the latter would have additional content.
Edits[]
Sonic's final line in the epilogue is changed from the original full comic version. His original line of "If we're back in the city and here to save the King...", which originally concluded on the following page with "...does that mean Naugus is involved?", is changed to a simple "Something strange is going on here...", due to the fact the story cuts off before the following page.
