History ComicBook / SonicTheHedgehogMegaManWorldsUnite

* PortalCrossroadWorld: Implied [[in the SequelHook with the Nexus. (AKA: the Genesis Nexus in some fan circles.)

In 2013, the worlds of the ''[[ComicBook/ArchieComicsSonicTheHedgehog Sonic the Hedgehog]]'' and ''[[ComicBook/MegaMan Mega Man]]'' comic series crossed over in the twelve part epic, ''[[ComicBook/SonicTheHedgehogMegaManWorldsCollide Worlds Collide]]'', a story which united two of gaming's most well-known blue heroes and brought about significant changes for the former series' future. Now, in 2015, the Blue Bomber and the Blue Blur's paths will be crossing over ''again'', in a new crossover titled ''Worlds Unite''. But this time, it's not just their worlds and time periods that are getting involved; joining the crossover are the cast of ''VideoGame/MegaManX'' and Sticks of ''ComicBook/SonicBoom'', along with many, ''many'' more from across Sega and Capcom's storied franchises.

* SirNotAppearingInThisTrailer: See UnexpectedCharacter.

* UnexpectedCharacter: Nobody saw the presence of the other Sega and Capcom characters coming prior to their announcement. The presence of ''Street Fighter'' characters was particularly surprising, given that license is already held by [=UDON=].
** Invoked in part two, when Fastidious Beaver and Comedy Chimp's appearance is heralded with the text box saying that they were "not the cameos you expected".
** Part three has [[VideoGame/SonicAdvance Gemerl]] show up!
** Sigma's many Maverick bosses were a given, but did anyone expect [[VideoGame/MegaManXtreme Geemel and Zain]] and [[VideoGame/MegaManXtreme2 Gareth and Berkana]] to also appear?

* BigBadEnsemble: ''Worlds Collide'' only featured Doctors Wily and Eggman and their minions as antagonists. This time, X's nemesis, Sigma, and the Deadly Six play a role as well, with Sigma serving as the crossover's BigBad.

* CompositeCharacter: Design-wise, [=NiGHTS=] has their ''Into Dreams'...'' lack of gloves (''Journey of Dreams'' gave them gloves), while everything else is from ''Journey of Dreams''.

* AGodAmI: Wily and Eggman tell the heroes that they propose this is Sigma's main goal: to siphon energy from different worlds and make himself a god. Of course, the first chance they get they try to do this themselves.

* PortalCrossroadWorld: Implied [[in TheStinger for the Nexus. (AKA: the Genesis Nexus in some fan circles.)

* MediumAwareness: When Axl and Sticks show up in ''Viewtiful Joe'' 's world, this gets lampshaded to heck and back.
--> '''Joe''': Dr. Cracken?! Cameo Leon?! What're they doing in the Real World?
--> '''Silvia''': No...I think we've wandered into some kind of franchise crossover!

--> '''Sticks''': Alright! Mission accomplished! Axl! Go destroy the unity engine while I recruit these two!
--> '''Axl''': Sure, but weren't you with partnered with X?[[note]] Earlier in the issue, Sticks had gone with X to the ''Monster Hunter'' world. All of a sudden, she showed up with Axl in this world.[[/note]]
--> '''Sticks''': I fell through a plot hole and now I'm here.
--> '''Axl''': Don't you mean "Genesis Portal"?
--> '''Sticks''': Whatever works for you kid, now move it!
--> '''Axl''': ''(Rolls eyes)'' Yes ma'am.

--> '''Sticks''': [=OhMyGosh!=] You guys break the fourth wall too?!
--> '''Joe''': Ehh...A little bit.
--> '''Silvia''': Mostly for the self-referential humor.

* ComicBookAdaptation: The main plot is essentially Archie's adaptation of ''VideoGame/SonicLostWorld'', what with the Deadly Six and the plot of draining the planet's power for the villain's schemes. It's also, in a way, their contribution to [[VideoGame/CapcomVsWhatever Capcom's Vs series]].

* CrisisCrossover: Much more UpToEleven then ''Worlds Collide'' as it not only involves Sonic and Mega Man's worlds once again. But brings in the ''Mega Man X'' timeline and the universe of ''ComicBook/SonicBoom'' as well as a multitude of characters from other game series. It is virtually a comic book version of ''[[VideoGame/CapcomVsWhatever Capcom vs Sega]]''.

* SidelinedProtagonistCrossover: This comicbook is mainly a crossover between ''VideoGame/{{Mega Man|Classic}}'', ''VideoGame/MegaManX'', ''Franchise/SonicTheHedgehog'', and ''SonicBoom''. In ''Sonic Boom''[='=]s case, however, the only characters with actual involvement in the crossover are Sticks the Badger, Fastidious Beaver, and Comedy Chimp, as they're the only characters who don't have counterparts in the main Sonic continuity (which is acknowledged in at least one of the crossover's backup humor shorts). The ''Boom'' versions of Sonic, Tails, Knuckles, and Amy have no involvement at all, and the ''Boom'' versions of Orbot and Cubot are the only counterpart characters to interact with someone from another franchise (specifically, the ''Mega Man X'' characters).

** Eggman and Wily put in a program in the robotized Sonic and Mega Man so that they'll battle each other and revert to normal in the process with the memory that Sigma is their enemy. While it does work, they had hoped the two would return to base first before that happened. But the world's merging put the two directly in each others sights from the get go. Once Sonic and Mega Man are changed back to normal, this tips Sigma off that the two doctors have betrayed him.

* AdvertisedExtra: A [[http://benbates.deviantart.com/art/Going-out-on-a-bang-518025199Giant poster made out of several connecting covers]] shows almost all characters that show up in story (with notable exception of Sonic Boom characters, sans Sticks) evn if they actually have very small roles. The most egregious examples include Dr Light and Auto (who only play small roles in Act 1), Team Dark ([[SacrificialLion who only appear briefly to die]]) and [[GhostsNGoblins Princess Prim Prim]] (who doesn't even make physical appearance in story, only being mentioned by Arthur).

* YouHaveOutlivedYourUsefulness: As soon as Sigma gives the Deadly Six armor that amplifies their powers to the point that they can control Sigma, they proceed to do exactly that. Unfortunately for them, Sigma is GenreSavvy enough to see a double cross coming and rigged the armor to allow him to control ''them''. The only thing that surprised him was how quickly he had to use that trump card.

* AlternateSelf: Though it initially looked like this would be defied, the Boom versions of the Sonic characters do appear in the crossover very briefly in a reference to the previous ''Boom'' issue, with appropriately witty text boxes to identify that these are the Boom versions for any readers that might be confused. It's pretty much handwaved, though, that Sticks promptly forgets her friends in her attempt to help X and their alternate(to her) selves, and the "Boom" crew don't show up again until the end.

* GenreSavvy: Several times
** Sticks reckons her reality's Doctor Eggman has some sort of interdimensional portal. And [[TheCloudcuckoolanderWasRight of course, she's right]].
** When it seem the United Army seemingly beat Sigma's army and Sigma himself, Sticks notes that they only took out a few Mavericks for him to go down so easily. [[spoiler: Sure enough, Sigma-3 busts out of his second body to confront the heroes.]]

** See the CameBrackWrong and EmptyShell examples below on this page? That was also [[JustifiedTrope the explanation]] for the BossRush in ''VideoGame/MegaManMaverickHunterX''.

* CallBack: Appropriate for a comic with no Fourth Wall, ''Sonic Boom'' #8 has Cubot complaining about how Eggman wanted "Seven-point-five paint jobs? For one robot?" and that it was for "more variants", a playful jab at ''Sonic Universe'' #75 and the fact it had seven "and a half" variant covers.
* CallingYourAttacks: Frankly, if the Street Fighter cast ''didn't'' do this, it would have been weird.
* CameBackWrong: When Sigma revives his fortress bosses and [[spoiler:Mavericks from X1 to X8]]. They all lack their personalities and memories, but Sigma deems this acceptable and doesn't bother to fix it. [[PlotHole Except they clearly show personalities later on, X-Hunters even recalling their last encounter.]]

* CelebrityParadox: of a sort. The Palicos X and Sticks encounter with the X-Hunters are wearing Sonic and Mega Man-themed gear (which yes, you can actually get in [=MH4U=]). Nobody notices this.

* CrisisCrossover: Much more UpToEleven then ''Worlds Collide'' as it not only involves Sonic and Mega Man's worlds once again. But brings in the Mega Man X timeline and the universe of ''ComicBook/SonicBoom'' as well as a multitude of characters from other game series. It is virtually a comic book version of ''[[VideoGame/CapcomVsWhatever Capcom vs Sega]]''.

** When its seem the United Army seemingly beat Sigma's army and Sigma himself, Sticks notes that they only took out a few Mavericks for him to go down so easily. [[spoiler: Sure enough, Sigma-3 busts out of his second body to confront the heroes.]]

** All of the Maverick bosses from X1-X8, most of the unique lesser Maverick villains, and some of the most iconic Fortress and Intro bosses make appearances. In fact, the only major and medium characters who don't appear are: [[VideoGame/MegaManX3 Doctor Doppler, Bit, and Byte]]; [[VideoGame/MegaManX4 Golonel, General, and Iris]]; [[VideoGame/MegaManX6 High Max and Isoc]]; [[VideoGame/MegaManX7 Red]]; and [[VideoGame/MegaManX8 Lumine]]. Nobody from ''VideoGame/MegaManXCommandMission'' appears either, as it was set after ''X8'' and Sigma had no part in it.

* LoinCloth / WalkingShirtlessScene: Ax Battler from ''VideoGame/GoldenAxe'', another first for the Sonic comics, at least for a human character.

* NeckSnap: M. Bison does this. ''To Blizzard Buffalo. One handed.''

* ArmyOfTheAges: The final UnitedArmy consists of everything from half-naked barbarians to Japanese martial artists to futuristic robots.

* BondVillainStupidty: Sigma's army of mavericks end up soundly defeating the army of heroes. But before the heroes can be finished off, Sigma stops the fight and and sends all of the Mavericks across time and space so they can get a move on with activating the world-absorbing bombs, leaving ''four'' mavericks to finish off a team of nearly 30 heroes. [[spoiler:But the heroes would have lost anyway were it not for the intervention of the Street Fighters]]

* WarArc: As it invovles multiple worlds and character, it ultimately winds up being this in the long run.
