Pre-Release Details
The following information has been revealed about the storyline:
 * It has been said that "no worlds will be safe" this time.
 * It will be bigger than the original crossover.
 * In addition to both Sonic and Mega Man's worlds, the worlds of Sonic Boom and Mega Man X will also be involved.
 * It was confirmed that for the Mega Man X universe, the event will take place chronologically between Mega Man X7 and Mega Man X8. As such, the crossover will include Sigma, X, Vile, Zero, Soldier Stonekong, Axl, Serges, Alia, Crush Crawfish, Signas, Duff McWhalen, Blaze Heatnix, and Web Spider amongst others.
 * Like Worlds Collide, it will have two anniversary issues cross through the series with Mega Man #50 and Sonic the Hedgehog #275. As well, like the original, Sonic Universe #75 will be the last issue of that title before the jump into the crossover. The story will also take up issues of the Sonic Boom comic series.
 * Sonic Universe #76's cover shows that Worlds Unite begins with Sonic Universe #76
 * The FCBD Sonic the Hedgehog/Mega Man 2015 flip book reveals that they will have two stories that lead into the story, most likely meaning that it will has partial stories from Sonic the Hedgehog #272 and Mega Man #49.
 * Xander Payne, a comic-exclusive villain in the Mega Man series, will play a role in the story, which also continues from "Dawn of X."
 * On February 10th, the covers for part 1 were shown, confirming the Archie-exclusive characters' inclusion. Further reveals have indicated that Dr. Noele Lalinde and Quake Woman will also be featured from the Mega Man comics, and that the Knothole Freedom Fighters will appear as part of Sonic's forces. It is currently uncertain whether any other comics-exclusive characters will be featured.
 * Cream the Rabbit, Cheese the Chao, and Big the Cat will join Sonic and Mega Man's team of allies in this crossover. Returning allies from Worlds Collide will include Proto Man-still in his Break Man persona from Mega Man 3-Knuckles the Echidna, Dr. Light, the members of Team Dark, the other Light Robot Masters, and Silver the Hedgehog. It does not appear that the Chaotix, Chaos, or Blaze the Cat will be returning, or that Chip, Dark Gaia, Tikal, or Dark Gaia's Minions will be present.
 * The Wily Number Robot Masters of Mega Man 2 and Mega Man 3 will also be returning, but appear to be part of Sonic and Mega Man's army of allies. It is unknown whether any Robot Masters from Mega Man 4 or other games will appear, as none of those games have been adapted in the Mega Man comic but Robot Masters from them have appeared in Archie Mega Man.
 * Sigma, the arch-enemy of X, will play a major role in this crossover, ending up in Sonic's world, enslaving Dr. Eggman and Dr. Wily, and recruiting the Deadly Six from Sonic Lost World into his army.
 * Sonic and Mega Man will be captured by Sigma's forces during the first act of the crossover with the former being turned into a new Roboticized Master, Sonic Man, and the latter being re-programmed with Eggman technology, becoming M'egga Man. The two will then be dispatched to each other's worlds, with Sonic Man battling the Robot Masters and M'egga Man challenging the Freedom Fighters.
 * Characters from other Sega and Capcom properties will be involved, the list including:
 * Alex Kidd and Stella from Alex Kidd
 * Billy Hatcher, Rolly Roll, Chick Poacher, and Bantam Scrambled from Billy Hatcher and the Giant Egg
 * Viewtiful Joe and Sexy Silvia from Viewtiful Joe
 * Ryu, Rei, Nina, Garr, Momo, Honey, Teepo, and Peco from Breath of Fire
 * NiGHTS and Reala from NiGHTS into Dreams
 * Ax Battler, Tyris Flare, Gilius Thunderhead and Death Adder of Golden Axe
 * Sir Arthur, Princess Prin Prin, and Red Arremer of Ghosts n' Goblins
 * Amaterasu and Issun of Okami
 * Vyse, Fina, Aika, Drachma, Gilder, Enrique, and Galcian of Skies of Arcadia
 * Ryu, Ken Masters, Chun-Li, Guile and M. Bison of Street Fighter
 * A Melynx and Gore Magala from Monster Hunter
 * Base Wing from Panzer Dragoon
 * Sigma's plan will involve merging Sonic and Mega Man's dimensions into a singular reality before moving on to the worlds of other characters.
 * Mega Man, X and all of the other heroic robots will fall under the Deadly Six's robot-controlling abilities-or possibly some other form of control-during Act 2, and will be forced to fight Sonic and the others. Possibly related to this will be battles between Break Man and Knuckles and Sticks and Roll.
 * Sigma and the Deadly Six will be sporting new armor, possibly provided by Dr. Eggman and Dr. Wily, who apparently escape Sigma with help from Xander Payne.
 * Based on all the covers revealed so far, Sticks The Badger seems to, for some reason, be the only Sonic Boom character to be involved in the crossover, as no other character from that universe has appeared on any cover thus far (not even variants). It is highly possible that this is to prevent confusion with younger readers. Sticks will apparently be instrumental in gathering allies from various worlds.
 * Just like when Eggman and Wily had an army of Robot Masters in the prequel, Sigma will lead an army of resurrected Mavericks against the heroes. He will also have an army of Mechaniloids who will operate under the command of the Deadly Six.
 * Sonic and Mega Man will use their super forms to fight Sigma in the final battle, and the worlds linked by the Genesis Portals throughout the crossover will be in danger as a result of the story.

Background Information

 * This arc holds the record in the series for the largest series of interconnecting covers: twelve of the variant covers connect to make a giant 4x3 image.
 * Several variant covers for the series feature characters who are unlikely to appear in the actual crossover:
 * Variant 2 for MM #50 features the Yellow Devil and Gravity Man, while Variant 4 features a man who appears to be Archie exclusive Dr. Pedro Astil.
 * Variant 2 for StH #275 features the Hooligans, Dark Gaia's Minions, Breezie the Hedgehog, the Super Special Sonic Search and Smash Squad, Walter Naugus, and several Egg Bosses: Clove the Pronghorn, Cassia the Pronghorn, Tundra the Walrus, Mordred Hood, Thunderbolt the Chinchilla, and Axel the Water Buffalo.
