Worlds Unite

Worlds Unite is an upcoming crossover between the Sonic the Hedgehog, Sonic Boom, and Mega Man comic series published by Archie Comics. It is the second crossover between the Sonic the Hedgehog and Mega Man comic series, the first being in 2013 with Sonic & Mega Man: Worlds Collide. This time, in addition to the main Sonic universe and the classic Mega Man universe, the worlds of Sonic Boom and Mega Man X will be involved as well. It is scheduled to begin in June 2015.

Development
Like in the previous crossover, the story will be written by Ian Flynn and all cover artwork for the issues partaking within the crossover will be drawn by Patrick "Spaz" Spaziante. According to Paul Kaminski:


 * "When the worlds of Sonic the Hedgehog and Mega Man collided in the pages of Archie Action comics, readers, fans and retailers made it the biggest crossover event in Archie Action history. That historic crossover storyline changed the comic book worlds of Sega and Capcom's iconic video game characters forever, but now an even bigger event is on the horizon. You saw what happened when worlds collided, now see what happens when Worlds Unite! And this time, no universe will be safe..."

On December 12, 2014, a promotional image of Sticks the Badger with Mega Man X appeared, indicating that the universes of Sonic Boom and Mega Man X will collide along with the Sonic the Hedgehog and Mega Man series. Paul Kaminski quoted:


 * "Not one, but TWO new casts will be joining the battle in this summer's Sonic/Mega Man WORLDS UNITE crossover event! The worlds of Sonic Boom and Mega Man X will be joining the fray, accompanying the worlds of Sonic the Hedgehog and Mega Man in the biggest crossover event in Archie Action history! The Sonic Boom comic series is part of the latest multi-media initiative from Sega, which includes video games, toys, and an all-new TV series on Cartoon Network! Mega Man X has been a staple of video game culture for decades, and we were thrilled to begin exploring that futuristic universe in 2014's Dawn of X storyline in the Mega Man comics! How will the slapstick antics of the ever-paranoid Sticks the Badger measure up against the futuristic action of X and the Maverick Hunters? Pick up Worlds Unite, starting this spring from Archie Action, to find out! And this is only the tip of the iceberg…"

As part of the lead-up to the crossover, beginning with Sonic Boom #6, Sonic the Hedgehog #271, and Sonic Universe #74, the respective series will have a countdown timer of how many issues are left before the start of the crossover on the covers, each being two issues. Mega Man #47 will also feature the same countdown on its covers, only it is three issues before the crossover in its case.

List of Worlds Unite issues
Like Sonic & Mega Man: Worlds Collide, Worlds Unite is split into three acts each consisting of four parts. Unlike the previous crossover however it spans over four titles: the initial three involved in the first crossover, plus the Sonic Boom comic series.
