Certain properties may also lend themselves more to being crossed over than others, which can affect the story being crafted. To take one example, ''Series/DoctorWho'' is a property that lends itself particularly well to being crossed over with others -- the TARDIS can literally land anywhere in time and space and do anything, enabling the writer to engage with a wide-range of genres, mediums, moods, and properties; all a writer really has to do to make a crossover is plonk the TARDIS down in a particular location and have the Doctor wander around until he meets the other characters. Other properties, however, may not have the luxury of this kind of freedom for writers, being tied to a particular genre, setting, theme, etc; it would take a lot more work to effect a successful crossover wherein characters from ''TheWire'' found a starship and travelled the galaxy until they met the [[Franchise/StarTrek USS Enterprise]] because the shows are quite different in genre, tone, setting, etc. Successful crossovers are aware of these limitations and manage to effectively overcome them.

* CelebrityParadox - of a sort; a lot of crossovers hinge on the fact that several characters (who are, of course, portrayed by the same performer) look rather alike, which enables them to find links between them; for example, both [[Series/{{Castle}} Richard Castle]] and [[{{Series/Firefly}} Malcolm Reynolds]] are played by the same actor (NathanFillion) and, as the former lives in an earlier time period to another, it's easy to suggest some kind of distant familial relationship or ancestry exists between the two that could be used to fuel the story (for example, Reynolds going back in time and encountering his ancestor).

On the other hand, props should usually be limited to those held in common with the focus series and/or the neutral setting. i.e. [[TheLordOfTheRings Frodo Baggins]] and [[HannahMontana Miley Cyrus]] should not be handling [[Franchise/{{Digimon}} Digivices]] unless that series is ''also'' involved [[FusionFic in some way]].

* ''[[Franchise/MarvelUniverse Marvel]] vs [[Franchise/TheDCU DC]]'' has its moments, but is, in many ways, a textbook example of how ''not'' to do a crossover. Missteps included letting fan vote (i.e., popularity) determine who won several of the fights (infamously leading to ComicBook/{{Wolverine}} beating Lobo); seriously misjudging characters' respective [[PowerCreepPowerSeep power levels]] (Franchise/{{Superman}} vs [[ComicBook//IncredibleHulk The Hulk]]) and/or popularity (Franchise/SpiderMan vs ... the clone ComicBook/{{Superboy}}?); having any fight they couldn't figure out how to write happen offscreen (Wolverine/Lobo), end inconclusively (Darkseid/Thanos), or be decided by outside factors (Franchise/{{Batman}}[=/=]ComicBook/CaptainAmerica, ends due to a random sewer tidal wave); and downright bizarre disrespect of the characters (suggesting that Franchise/WonderWoman could lift the hammer of [[ComicBook/TheMightyThor Thor]]? Cool. Suggesting that she'd ''need'' it to put up a good fight against ComicBook/{{Storm}}... and would lose anyway? Insane).

* The first type is the Dimensional Crossover: Each series involved is in their own dimension, with some kind of travel (accidental or intentional) or NegativeSpaceWedgie bringing them together. In these cases, a good portion of the story is usually involving how to get the character(s) who are out of time and out of place back to where they belong. '''Example''': [[MarvelComics Marvel]] and [[DCComics DC]]'s ''[[ComicBook/JLAAvengers JLA/Avengers]]'' crossover was done like this.

Official crossovers are tricky, because so many fictional properties are owned by a wide range of corporate media interests, often giving rise to tangled and[=/=]or complex issues of copyright in the process. On the most simple level, you rarely see certain properties come together officially because different corporations own them; for example, you rarely see Comicbook/SpiderMan and Franchise/{{Batman}} hanging out because one is owned by Marvel and the other DCComics, and the DC writers don't have the right to use SpiderMan in their stories (and vice versa of course). Of course, on certain occasions the two have and can be brought together, but it's usually very rare and depends on the interest and goodwill of all copyright owners. And that's when the issue of copyright is clear-cut; certain characters exist within a legal quagmire of copyright issues.

Cool. Suggesting that she'd ''need'' it to put up a good fight against ComicBook/{{Storm}}... and would lose anyway? Insane).

* The [[PoliceProcedural police procedurals]] ''HomicideLifeOnTheStreet'' and ''LawAndOrder'' crossed over so frequently that after Homocide ended, Det. JustForFun/JohnMunch actually became a character on ''[[LawAndOrderSpecialVictimsUnit Law & Order:SVU]].''

* ''[[Franchise/MarvelUniverse Marvel]] vs [[Franchise/TheDCU DC]]'' has its moments, but is, in many ways, a textbook example of how ''not'' to do a crossover.

Cool. Suggesting that she'd ''need'' it to put up a good fight against ComicBook/{{Storm}}... and would lose anyway? Insane).

* ''[[{{JLA-Avengers}} JLA/Avengers]]'' gets right everything that ''Marvel vs DC'' (see below) gets wrong. Both franchises are respected right down to established differences in each universe's physics and geography being acknowledged. The difference in power levels between the universes is incoporated into the story instead of being handwaved aside. The story even dares to admit that certain characters would easily defeat others while allowing some of them to be smart enough to ''not'' fight for no reason.

* ''TheLeagueOfExtraordinaryGentlemen'', both in comic and {{film}} format, is a rare example of an officially published MassiveMultiplayerCrossover (it helps that most of the central characters are from works that are at least OlderThanRadio, if not older, and thus exist in the [[PublicDomainCharacter public domain]]; works which aren't tend to be alluded to in dialogue), wherein practically every detail is taken from another work in an attempt to put together a cohesive fictional universe for all (or at least as close to all as possible) of human storytelling. The comic is by Creator/AlanMoore and Kevin O'Neal and is well worth a look.
* ''KingdomHearts'' took two works that sounded as if they definitely ''should not'' be crossed with each other (Eastern animation meets Western animation?! ItWillNeverCatchOn!) and managed to make the final result ''great''.

* Whilst ''TheLeagueOfExtraordinaryGentlemen'' in comic form is widely agreed to belong in the 'Greats' category, most would put the movie based on same squarely in the 'Epic Fails' column. Not only does it water down and dilute the original, it's also in many ways quite a poorly-told story.

* The novel ''Planet X'' is an officially published (though almost certainty out of [[{{Canon}} continuity]]) crossover between the ComicBook/{{X-Men}} and ''Series/StarTrekTheNextGeneration''. (And, yes, it mentions [[PatrickStewart the uncanny resemblance between Xavier and Picard]]... despite being published ''before'' the movie was cast!).

* '''Overlapping Adventures''': A smaller scale version of the Ultimate Showdown where the characters from one franchise happen to be working on the same (or a similar) problem to the characters from another franchise, only for the two to eventually collide; for example, Detectives Briscoe and Logan from ''LawAndOrder'' might be investigating a murder only for Agents Mulder and Scully from ''TheXFiles'' to be investigating the same crime, or the crew of the [[Franchise/StarTrek USS Enterprise]] might be investigating a suspicious phenomenon on a distant planet while at the same time [[Series/DoctorWho the TARDIS]] has arrived there. Official crossovers on a smaller scale to the Ultimate Showdown might use this.

* ''TheLeagueOfExtraordinaryGentlemen'', both in comic and {{film}} format, is a rare example of an officially published MassiveMultiplayerCrossover (it helps that most of the central characters are from works that are at least OlderThanRadio, if not older, and thus exist in the [[PublicDomainCharacter public domain]]; works which aren't tend to be alluded to in dialogue), wherein practically every detail is taken from another work in an attempt to put together a cohesive fictional universe for all (or at least as close to all as possible) of human storytelling. The comic is by AlanMoore and Kevin O'Neal and is well worth a look.

* [[FightingGame Fighting games]] in which characters from different franchises - or even [[MarvelVsCapcom different companies]] - fight each other are commonplace. But ''VideoGame/MortalKombatVsDCUniverse'' actually took the rare step of coming up with a story mode and with a plot that explains ''how'' and ''why'' the characters are fighting each other, and even goes the extra mile of explaining why characters like {{Superman}}, SelfDemonstrating/TheJoker, Liu Kang, and Raiden are having fist fights [[PowerCreepPowerSeep on equal footing]].

Who are the fictional characters you are bringing together? What universes are they from? How are they coming together?
* One of the most basic is a Dimensional Crossover: Each series involved is in their own dimension, with some kind of travel (accidental or intentional) or NegativeSpaceWedgie bringing them together. In these cases, a good portion of the story is usually involving how to get the character(s) who are out of time and out of place back to where they belong. '''Example''': [[MarvelComics Marvel]] and [[DCComics DC]]'s ''[[ComicBook/JLAAvengers JLA/Avengers]]'' crossover was done like this.
* Another common type is the Temporal Crossover: When the series involved take place in different time periods, you may choose to say that they take place in the same universe, just at different points along the timeline. Works by the same author may have this be true officially. '''Example''': The MarvelCinematicUniverse: ''Film/CaptainAmericaTheFirstAvenger'' happened in the 1940s, while the ''Film/IronMan'' films take place in the present.
* Adjacent Crossovers are usually what happens when the series involved take place in the same universe and at the same time. Distance, focus, and circumstances simply kept the two apart, until now. '''Example''': the various {{Intercontinuity Crossover}}s and guest appearances between different books of Marvel Comics (or DC). SpiderMan and the ComicBook/TheAvengers both live in New York City of the same universe and generally do their own thing, but sometimes circumstances put them together to save the day.
* A Fusion or Merged crossover is usually restricted to the likes of Fan Fiction and Alternate Universes: where the series are brought together so closely that elements become mixed together and/or replace each other. '''Example''': The UltimateMarvel universe (about the only official version of this there is) is a lot more intertwined between titles than the normal Marvel Universe. The fan fics ''FanFic/{{Renegade}}'' and ''FanFic/ProtocultureEffect'' both replace the [[Franchise/MassEffect SystemsAlliance]] with the Human forces of another Sci-Fi series.

Usually, most crossovers don't have to think about costumes, as the standards of the Location take precedence, followed by the characters' ordinary LimitedWardrobe. However, a humorous (or {{FanService}}y) moment can be had when certain characters have to dress in a certain way, usually either to fit in with the aforementioned setting, or as a visual ActorAllusion. [[hottip:*:Other reasons for dressing up (see {{CostumeTropes}}) are handled just as well in other genres. ]] If the crossover author ''does'' have reason to expand wardrobes, one must take '''great''' care to avoid CostumePorn.

How will the crossover affect the series' involved? Will this be a one-shot that leaves the Status Quo of each series mostly untouched, or will there be ongoing effects that change everyone involved (for good or ill)?

Official crossovers are tricky, because so many fictional properties are owned by a wide range of corporate media interests, often giving rise to tangled and / or complex issues of copyright in the process. On the most simple level, you rarely see certain properties come together officially because different corporations own them; for example, you rarely see Comicbook/SpiderMan and Franchise/{{Batman}} hanging out because one is owned by Marvel and the other DCComics, and the DC writers don't have the right to use SpiderMan in their stories (and vice versa of course).

To take one example, ''Series/DoctorWho'' is a property that lends itself particularly well to being crossed over with others -- the TARDIS can literally land anywhere in time and space and do anything, enabling the writer to engage with a wide-range of genres, mediums, moods and properties; all a writer really has to do to effect a crossover is plonk the TARDIS down in a particular location and have the Doctor wander around until he meets the other characters.

LetsYouAndHimFight can be a bit hackneyed, since it's a slightly cliched way of creating tension between the characters; perhaps in your crossover the characters could have a moment's friction, but actually decide to work together from the start? Or even old friends (albeit unseen ones to other characters)

* StatusQuoIsGod- by then end everything will be as it started, since the crossover is not allowed to override the actual series. This doesn't apply in fanfiction unless the writer wants it to, tho.

* '''The Ultimate Showdown Of Ultimate Destiny''': Basically, the properties have been brought together for one hell of an almighty battle. May involve LetsYouAndHimFight (as the plot-namer in this case does) or a VillainTeamUp (or even Villain Battle / NegativeSpaceWedgie that threatens the respective worlds / realities of each property. Official crossovers tend to use this, since the rarity of the characters meeting tends to call for some kind of epic circumstances to surround it; it would be a bit underwhelming to have the Avengers and the Justice League finally meet up only for the entire plot to revolve around hunting down some random mugger, after all. The CrisisCrossover may also be involved here as well.

* '''Two Characters Walk Into A Bar''': A crossover which centres around two (or more) characters who just happen, for whatever reason, to cross paths over the course of their day-to-day lives. Often done on a smaller scale than the Overlapping Adventures, and usually the hallmark of shorter works of fanfiction. The typical example tends to involve a character from one franchise going into a bar at the end of their day and striking up a conversation with whoever they end up sitting next to, who turns out to be a character from another franchise. The focus is usually on CharacterDevelopment and Character Exploration, usually centred around VillainsOutShopping or HeroesGoneFishing; how do these two characters spark off each other? Naturally, it doesn't ''have'' to be a bar, but it's generally just some similar small, every day activity which throws these two together rather than a crisis as above (although the crisis might form the background to the story).
* '''Ten Times...''': A specific form of ensemble story common to fanfiction in which a certain number of properties (usually five or ten) are brought together around a certain theme or connection, with the story told in a number of different segments each focussing on a different property. Often, there is one 'overarching' property which is then linked to the others, which otherwise might not meet up; alternatively, each segment might focus on a different property entirely, with the only connection being this overall theme. Named because the usual title / summary for this story tends to be along the lines of "Ten Times Character A Met / Did This."

!!'''Set Designer''' / '''Location Scout'''

The PlotTailoredToTheParty usually comes into play here; since the point of a crossover is to see the characters interact, this usually means that each character will get a chance to show off their usual skills or {{Iconic Item}}s. Also, Technology / {{Magitek}} from series A handled by characters from Series B is usually good for some laughs.

You may also have to pick and choose which characters from each franchise are going to appear; if you try and include all of them, it's going to get crowded. You might wish to consider what links can be drawn between characters -- the CelebrityParadox example noted above might not be practical, but you can consider careers, backstories, etc in deciding who is going to meet who.
