History ComicBook / SonicTheHedgehogMegaManWorldsUnite

* NearVillainVictory: A posthumous example. [[spoiler: Sigma-3 is destroyed by Super Sonic and Mega Man thanks to the doctors tampering with the engine that's giving him his power making him venerable. But even with him gone, he caused too much damage to the worlds that even Chaos Control can't fix it. What's more Eggman and Wily take over the engine and are posed to re-write reality. It's only thanks to Xander taking over the machine and using it to kill Sigma before he jumped to Sonic's world, thus keeping the crossover events from happening, that everyone is saved.]]

* CurbStompBattle: Used ''a lot'', and mercilessly so.

* IAmTheNoun: When the Mega City cops tell Sonic Man to drop his weapons, he replies "I ''am'' the weapon". He's not just bragging.

-->--'''Xander Payne'''

In 2013, the worlds of the ''[[ComicBook/SonicTheHedgehogArchieComics Sonic the Hedgehog]]'' and ''[[ComicBook/MegaManArchieComics 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.

''Worlds Unite'' began in May of Spring 2015 and ended in August 2015. As with ''Worlds Collide'', it ran through four issues each of ''Sonic Universe'',''Sonic Boom'', ''Sonic the Hedgehog'' and ''Mega Man'' in that cycle order through the three months. The series also included two direct-market tie-in books expanding on battles shown in the crossover, appropriately titled ''Worlds Unite: Battle Books''.

Now has a [[Characters/SonicTheHedgehogMegaManWorldsUnite character page]] that needs love.

-->'''Xander Payne'''

->'''Xander Payne:''' Oh, Wily will have his reckoning. We ''all'' will. The time will come, and '''Worlds''' will '''Collide''' again...

The story picks up on plot threads that began in Mega Man's ''Dawn of X'' storyline, as well as prequels in the prior issues of both Sonic books. In X's timeline, sometime after the events of ''VideoGame/MegaManX7'', [[Characters/MegaManXSigma Sigma]] discovers the existence of the mysterious Genesis Portals, which lead to different dimensions. Believing that these portals are the key to his further evolution, the living virus travels to Sonic's world, where he takes control of Dr. Eggman. After reuniting him with his former partner-in-crime from ''Worlds Collide'', Dr. Wily, he puts them to work in building the means for his latest conquest, triggering a conflict that will span multiple dimensions.

''Worlds Unite'' began in May of Spring 2015 and ended in August 2015. As with ''Worlds Collide'', It ran through the issues of the respective series, with added benefit of having four comics rather then three to work with (''Sonic Universe'',''Sonic Boom'', ''Sonic the Hedgehog'' and ''Mega Man'' in that order) through the three months. The series also included two direct-market tie-in books expanding on battles shown in the crossover, appropriately titled ''Worlds Unite: Battle Books''.

* 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 [[VideoGame/GhostsNGoblins Princess Prim Prim]] (who doesn't even make physical appearance in story, only being mentioned by Arthur).
* 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.

* ArcWelding: Running with the CosmicRetcon feeling, ''Sonic Boom'' #8 revealed that ''ComicBook/SonicTheHedgehogMegaManWorldsCollide'' happened the exact way. However, the Chaos Emerald that enabled the crossover was flung to Mega Man's world by the Time Eater's space-time rampage in ''VideoGame/SonicGenerations'' in the rebooted ''Sonic'' continuity, rather by the first Genesis Wave in the ''Sonic Genesis'' arc in the old continuity. As such, (Modern) Eggman encountered Wily while stranded in a void during TheStinger of ''Generations'' (what happened to Classic Robotnik in that same scene is left unstated) and not while barking orders to his Grandmasters in his base.
* ApologeticAttacker: In issue 7: [[spoiler:when all Robot Masters, Maverick Hunters, Bunnie, and Gemerl are mind controlled by the Deadly Six. Snake Man is notably insincere, however.]]

* AttackOfTheFiftyFootWhatever: Sigma's new body is ''huge''.

* TheBadGuyWins: The first three issues which make up the first act are pretty much this as [[spoiler: Sonic and Mega Man are captured and robotized, then sent to their opposite worlds where they easily trounce all the opposition before them before activating a beacon and merging the two worlds.]]

* BrickJoke: When Sticks goes with the Maverick Hunters, she requests she get to say "Take me to your leader". She doesn't get the chance when the group arrive at the fused world due to the Freedom Fighters and the Robot Masters already talking about the situation. But when she falls into a Genesis Portal and [[spoiler: winds up in the ''Street Fighter'' world, where she meets Chun-Li]], she gets to say the line.

* TheCameo: The Off Panel comic in ''Sonic Universe'' #77 features Mama Robotnik from ''WesternAnimation/AdventuresOfSonicTheHedgehog'' and even the ''[[WesternAnimation/CaptainNTheGameMaster Captain N]]'' version of Mega Man of all characters.

* CosmicRetcon: The one that hit Sonic's world after ''Worlds Collide'' gets discussed by Eggman at one point, and its effects noted, namely that the cause of his and Dr. Wily's original meeting is now ''VideoGame/SonicGenerations''.

** [[spoiler: Team Dark is featured in the crossover poster (as seen on the image there), but are only appear briefly in third issue and are killed when a building fuses with the G.U.N airship and explodes. Don't worry, this isn't permanent.]]

* EarlyBirdCameo: [[spoiler: Chun-Li shows up near the end of Part 6 (Sonic Boom #9) after Sticks gets tossed into a Genesis portal during the battle outside Sigma's fortress and winds up in the ''Street Fighter'' world.]]

* EnergyRingAttack:
** Sonic Man can fire rings that bind enemies.
** Rouge Woman's "Black Wave" attack has her firing an EnergyBall propelled forward by purple energy ripples. It is used to [[TheParalyzer stun]] enemies.

* FaceFramedInShadow: [[spoiler: Chun-Li in Part 7 (Mega Man #51) when she interviews Sticks.]]
* FightingFromTheInside: All robots [[spoiler:''except'' Snake Man.]]

* TheHeart: Sticks' primary role is this. While she's a decent fighter, her most prominent ability is the ability to win people over with her pluck- The Maverick Hunters, four Street Fighters, Fastidious Beaver and Comedy Chimp, Viewtiful Joe and Sylvia, Felyne and Palico [[spoiler:And even the eldritch nightmare that is Gore Magala]]
* HeelFaceTurn: [[spoiler:Wily's Robot Masters have turned good. Subverted with Shadow Man who states he's still loyal to Wily.]]

** The heroes raid on Sigma's Base seems to be going well and they manage to defeat the Deadly Six. [[spoiler: However the Zeti use their robot controlling powers to take control of Mega Man, the Robot Masters and the Maverick Hunter and turn them against the Freedom Fighters.]]
** Wily and Eggman [[spoiler: manage to disable the Deadly Six's powers and bring the robots back to normal.]] Before the heroes have a chance to recover though, Sigma siphons the energy from the two merged worlds, grows giant and summons every Maverick from the X series, grossly outnumbering the heroes.

* HourglassPlot: ''Worlds Collide'''s event ends with Mega Man's universe returning to normal but Sonic's universe suffering a CosmicRetcon. While Mega Man's universe doesn't have the same effect by the time this event closes, small changes happen regarless, like Xander Payne becoming Mr. X, plus a world of unknown origin is born from the aftermath. Sonic, Sticks and Mega Man X's universes, meanwhile, are back to normal.

* NearVillainVictory: A post-humorous example. [[spoiler: Sigma-3 is destroyed by Super Sonic and Mega Man thanks to the doctors tampering with the engine that's giving him his power making him venerable. But even with him gone, he caused too much damage to the worlds that even Chaos Control can't fix it. What's more Eggman and Wily take over the engine and are posed to re-write reality. It's only thanks to Xander taking over the machine and using it to kill Sigma before he jumped to the Sonic world, thus keeping the crossover events from happening, that everyone is saved.]]

** There's also Sigma's invasion of other worlds: [[spoiler:So far, he's managed to piss off Astaroth and Wizeman, leading them to send Firebrand and Reala with the heroes and their usual arch-nemesis. As well, M. Bison has declared that Sigma has now gotten "the full attention of Shadaloo".]]
** In the end [[spoiler: Eggman and Wily tampering with the Eternal Engine weakened Sigma enough for Sonic and Mega Man to destroy him. Likewise when they finally took control of it, it allowed Xander the opportunity to stop the crossover from happening by killing Sigma before he has a chance to jump to Sonic's World.]]
* NotSoDifferentRemark: Quake Woman and Nicole (ironically both [[CanonForeigner Canon Foreigners]] in their respective series) find they actually have a lot in common when it comes to trying to understand emotions.
* OffscreenTeleportation: Sticks gets to team of with X to got into the Monster Hunter world, while going with Ryu, Chun-Li, Ken, and Guile in to the ''Street Fighter'' universe, while at the same time going with Axl to the world of Viewtiful Joe, by falling into a "plot hole" (which Axl tries to correct as Genesis Portal)

* PowerCreepPowerSeep: All over the place, though most notable when Antione's perfectly ordinary military sword manages to block a laser blade.

* RippleEffectProofMemory: Zigged Zagged at the end. [[spoiler: Sonic, Mega Man, Wily, and Eggman somewhat recall the crossover but not the full details just that something happened and their fellow partners had a hand in it. Sticks, Comedy Chimp and Fastidious Beaver however remember it vividly for some reason but Sticks surmises since it technically never happened with the timeline change, the other heroes recruited likewise won't recall the crossover when they went back to their worlds. Mr. X also seems aware of what happened to Wily, since Wily stated that it was ''HIM'' all along, insinuating that Mr. X may indeed be a time-aged Xander Payne, since the doctors DID warn him about the trickery of time travel.]]

** Sticks surprisingly enough. She's the one who brings X, Zero and Axl to the other heroes which fill them in on what's going on. During the initial battle with Sigma is the who brings [[spoiler: the Street Fighter heroes]] to come help the others and gives Sally the idea transverse to other world and bring in other heroes (and some villains) to come help combat Sigma's threat.
** [[spoiler:Eggman, Wily, and Xander for Sigma. He never anticipated that he could be defeated if anybody actually ''find'' the Unity Engine, let alone tamper with it. Xander in particular uses the Engine's power to pinpoint when Sigma jumped to Mobius and blasted him, negating the whole crossover.]]
** Ian Flynn originally wanted Mega Man X to get his OWN Super form at the end of the crossover (imagine X in his Ultimate Armor with the power of the Chaos Emeralds), but unfortunately, Sega 86ed that idea.

* WhatHappenedToTheMouse: Despite being central antagonists for the first third, the Deadly Six disappear afterward and are last since getting carted away by Big. It's surmised that they were thrown into the Sky Patrol brig while everyone was preparing to world hop to recruit heroes. And considering Sigma later destroyed the Sky Patrol and the heroes that stayed behind had to quickly evacuate... yeah.

** Averted when the amassed Maverick army clashes with the heroes. Unlike in "Worlds Collide" where the Robot Masters went down by the handfuls in comedic ways, the Mavericks easily hold their own and even turn the tables on the heroes, with some like Grizzly Slash (Crescent Grizzly) and Axle the Red (Spike Rosered) even knocking aside ''three'' heroes at once.

** A much more egregious example: the [[https://static.wikia.nocookie.net/sonic/images/0/0f/Sonic_Boom_-8.jpg/revision/latest?cb=20150725111437 main cover]] for ''Sonic Boom'' issue 8 (part 2) very prominently features Signas and Alia of ''Mega Man X'', giving the impression that they'd be important players in the story. ''They don't appear in the crossover at all''.

* CoversAlwaysLie: [[spoiler: Team Dark is featured in the crossover poster (as seen on the image there), but are only appear briefly in third issue and are killed when a building fuses with the G.U.N airship and explodes. Don't worry, this isn't permanent.]]

* ''VideoGame/BillyHatcherAndTheGiantEgg'': Billy Hatcher, Rolly Roll, Chick Pocher, Bantam Scrambled

The story picks up on plot threads that began in Mega Man's ''Dawn of X'' storyline, as well as prequels in the prior issues of both Sonic books. In X's timeline, sometime after the events of ''VideoGame/MegaManX7'', Sigma discovers the existence of the mysterious Genesis Portals, which lead to different dimensions. Believing that these portals are the key to his further evolution, the living virus travels to Sonic's world, where he takes control of Dr. Eggman. After reuniting him with his former partner-in-crime from ''Worlds Collide'', Dr. Wily, he puts them to work in building the means for his latest conquest, triggering a conflict that will span multiple dimensions.

* 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/CapcomVs Capcom vs Sega]]''.

** ''Worlds Unite'' establishes that in the rebooted ''Sonic'' comic continuity, first contact between Eggman and Wily occured during TheStinger of ''VideoGame/SonicGenerations'' on the ''Sonic'' side, in which Modern Eggman and Classic Robotnik were stranded in a void, and thus it was Wily who helped Eggman return to normal space-time. Classic Robotnik is never brought up by Eggman during his recollections of Wily's contact, leaving his means of escaping a mystery (he does reappear in later ''Sonic'' Classic WholeEpisodeFlashback issues set after ''Generations'').

* ArcWelding: Running with the changed universe feeling, ''Sonic Boom'' #8 revealed that ''ComicBook/SonicTheHedgehogMegaManWorldsCollide'' happened the exact way. However, instead of a Genesis Wave hitting, it was the end of ''VideoGame/SonicGenerations'' allowing Eggman to meet Dr. Wily.

*** ''Skies of Arcadia'' vs. [[VideoGame/MegaManX5 Duff [=McWhalen=] (Tidal Makkoeen/Whale)]]: As a robot whale, Duff is seen by the Blue Rogues as a mockery of Rhaknam.
*** ''Street Fighter'' - Ryu, Ken Chun-Li and Guile vs. [[VideoGame/MegaManX4 Magma Dragoon]]: Dragoon could explicitly perform Hadoukens and Shoryukens in-game, and he also wears a bead necklace akin to Akuma's. [[spoiler:Here, he's killed by a Shoryuken and a Hadouken.]] Plus, M. BISON fights Blizzard BUFFALO.

*** ''Billy Hatcher'' vs. [[VideoGame/MegaManX7 Wind Crowrang]] and [[VideoGame/MegaManX5 Dark Dizzy (Dark Necrobat)]]: As he explicitly points out, Billy Hatcher fights crow monsters on a regular basis, and bats are creatures of darkness.
*** ''Panzer Dragoon'' vs. [[VideoGame/MegaManX5 Mattrex (Burn Dinorex)]] and [[VideoGame/MegaManX8 Gigavolt Man-o-War]]: The ''Panzer Dragoon'' series (bar the third game) and [[UnexpectedGameplayChange Gigavolt Man-o-War's stage]] are both {{Rail Shooter}}s. In Mattrex's case, the only dragon Maverick was already killed in the previous issue due to his pre-existing ''Street Fighter'' connections, so the next best thing had to be settled on - the only dinosaur Maverick.
*** ''Breath of Fire'' vs. [[VideoGame/MegaManX3 Toxic Seahorse]] and [[VideoGame/MegaManX5 The Skiver (Spiral Pegasus)]]: Combined, they resemble game's final boss who is winged snake with toxic based attacks.

*** ''Viewtiful Joe'' vs. [[VideoGame/MegaManX5 Squid Adler (Volt Kraken)]] and [[VideoGame/MegaManX Sting Chameleon]]: Joe compares them to ''Viewtiful Joe 2'' bosses Dr. Cranken and Cameo Leon, who are... you guessed it, a squid man and a chameleon.

* DubNameChange: Inverted. Ian Flynn personally dislikes the Music/GunsNRoses MusicalThemeNaming for the ''VideoGame/MegaManX5'' Mavericks and so refers to them by names based on their Japanese ones (refer to [[YMMV/MegaManX5 that game's YMMV page]] for the list) - or in the case of Duff [=McWhalen=], his actual Japanese name "Tidal Makkoeen"[[note]]Flynn admitted that was an editorial slip-up.[[/note]] - during the third act. Ergo, Vyse cannot claim he once fought a robot named "Duff [=McWhalen=]".

* PortalCrossroadWorld: Implied [[spoiler:in the SequelHook with the Nexus. It is also known as the Genesis Nexus in some fan circles.

* WhatHappenedToTheMouse: Despite being central antagonists for the first third, the Deadly Six disappear afterward and are last since getting carted away by Big. It's surmised that they were thrown into the Sky Patrol brig while everyone was preparing to world hop to recruit heroes. And considering Sigma later destroyed the Sky Patrol and the heroes that stayed behind had to quickly evacuate...yeah.

* TheWorfEffect: It only takes half of the Deadly Six to capture Sonic and Mega Man each. This is justified by the fact that they're using armor that enhances their already considerable powers. They are also able to control Sigma's body, but not his mind, while he is able to easily control their bodies ''and'' minds thanks to the armor he gave them.

* LoadsAndLoadsOfCharacters: The first few parts of the story will feature twenty characters from the Sonic and Mega Man franchises, ''before'' the other universes start showing up. The Off Panel comic in ''Sonic Universe #77'' even lampshades it.
** 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 Colonel, 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.

* AbsenteeActor: When all of the [[spoiler:revived Mavericks from X1 through X8]] begin attacking the group, [[spoiler:Iris and the Colonel]] are not there, which is noted by X and Zero.
* ADogNamedDog[-/-]EveryoneCallsHimBarkeep: "Felyne" is the name of the species of catlike creatures that sometimes help Monster Hunters, while "Palico" is a name for the occupation of doing so. Used here because Palicos have randomly-generated/player-given names in the games.

* ContemptibleCover: The [[http://vignette1.wikia.nocookie.net/archiesonic/images/a/a2/MM_50_V4.jpg/revision/latest?cb=20150311221321 fourth variant cover]] to ''Mega Man'' #50 has earned some massive derision, due to, among other things, the massive OffModel looks for Quake Woman and Xander Payne... if that even ''is'' Xander Payne.

** Rouge Woman's "Black Wave" attack has her firing an EnergyBall propelled forward by purple energy ripples. It is used to [[StunGun stun]] enemies.

* ''VideoGame/StreetFighter'': Ryu, Ken, Guile, Chun-Li, M.Bison, Balrog and Vega.

* 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/CapcomVs Capcom's Vs series]].
* ContemptibleCover: The [[http://vignette1.wikia.nocookie.net/archiesonic/images/a/a2/MM_50_V4.jpg/revision/latest?cb=20150311221321 fourth variant cover]] to ''Mega Man'' #50 has earned some massive derision, due to, among other things, the massive OffModel looks for Quake Woman and Xander Payne... if that even ''is'' Xander Payne.
* ContrivedCoincidence: After the worlds are merged, this conveniently puts all the protagonists in the same area so that they'll be able to meet and team up.

* CosmicRetcon: The one that hit Sonic's world after ''Worlds Collide'' gets discussed by Eggman at one point, and its effects noted, namely that the cause of his and Dr. Wily's original meeting is now ''VideoGame/SonicGenerations''.

In 2013, the worlds of the ''[[ComicBook/SonicTheHedgehogArchieComics 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.

* NotSoDifferent: Quake Woman and Nicole (ironically both [[CanonForeigner Canon Foreigners]] in their respective series) find they actually have a lot in common when it comes to trying to understand emotions.

* TheStarscream: Sigma convinces the Deadly Six to turn on Eggman early on in the story, after freeing them from the control of Eggman's "Cacophonic Conch". Then, they try to turn on Sigma too, but he has a fail-safe built into the armor he gave them.

* ''VideoGame/BreathOfFire'' (specifically ''VideoGame/BreathOfFireIII''): Ryu, Garr, Nina, Momo, Honey, Rei and Peco

* AuthorAppeal: Ian Flynn admitted that the reason why ''VideoGame/BreathOfFire3'' is specifically in the crossover is more or less a case of favoritism, since it's his favorite game in the series. He also holds particular esteem for ''Skies of Arcadia'', and has wanted to work with the characters ever since Vyse's guest spot in ''Sonic Universe''.
