A Motif Merger is a stylistic 'beat' sometimes used during a crossover. It's when both 'sides' have certain things that are their trademarks, and (during the crossover) there's a symbolic moment where the two motifs are either swapped or combined.



[[folder:Anime and Manga]]
* Tet, PhysicalGod of Games in ''LightNovel/NoGameNoLife'', merges various game icons into her/his design, among them symbols of poker and chess. (S)he also has a die as an earring.

[[folder:Comic Books]]
* The page illustration is the logo for DC's current ''ComicBook/SupermanBatman'' series, Superman's shield logo inside Batman's bat logo. [[http://en.wikipedia.org/wiki/File:Superman-batman_8_cvr_-_large.jpg For example, the cover of issue 8.]] The first arc of the series was adapted into the direct-to-video ''WesternAnimation/SupermanBatmanPublicEnemies'', mentioned below.
* [[http://dc.wikia.com/wiki/File:Trinity_Logo.jpg The logo]] for the ''Comicbook/{{Trinity}}'' series combined Franchise/{{Superman}}, Franchise/{{Batman}}, and Franchise/WonderWoman's symbols.
* Devils Due's ''GIJoe VS Transformers'' used a mash-up between the Cobra and Decepticon symbols in advertisements, but not in the actual comic (except to separate issues in the collected edition).
* ''ComicBook/ArchieMeetsThePunisher'' features Comicbook/ThePunisher's skull-logo crossed with [[Franchise/ArchieComics Archie]]'s facial features.

* In ''Literature/TheDresdenFiles'' fic ''[[http://archiveofourown.org/works/1904676?view_full_work=true Restitution]]'', [[spoiler:Lash]] (a redeemed FallenAngel) merges her hourglass sigil with an infinity sign, symbolizing her reconciliation with God.
* ''Fanfic/UndocumentedFeatures'': After becoming a Transformer, Martin Rose uses an Autobot logo superimposed over a Wedge Defense Force logo on his clothing.

[[folder:Films -- Animated]]
* In the animated Franchise/{{DCAU}} crossover movie "World's Finest", the Bat-Signal (Batman's emblem) is broadcast onto the globe on top of the Daily Planet Building (Superman's).
* The exact logo at the top of the page also appears in-universe in ''WesternAnimation/SupermanBatmanPublicEnemies'' [[spoiler: on the chest of a giant robot that Toyman, Japanese wunderkind Hiro Okamura, built to destroy a Kryptonite asteroid that would hit Earth. Cut him some slack: he designed it when he was seven.]]

[[folder:Films -- Live-Action]]
* The movie ''Film/FreddyVsJason'' had a moment of mixing icons: a slow pan down from tree level, coming down onto a sign reading "Elm Street", while the soundtrack played the ''Friday the 13th'' "ki-ki-ki-ki, ma-ma-ma-ma" leitmotif.
* ''Film/BatmanVSupermanDawnOfJustice'': Just look at the page image, then look at the trope image. [[MythologyGag It's is the logo]] for DC's Comicbook/SupermanBatman series, albeit with more of an influence from the Superman logo from UsefulNotes/TheGoldenAgeOfComicBooks and the Batman logo from ''ComicBook/BatmanTheDarkKnightReturns''.
* A more literal example comes from ''Franchise/IndianaJones''. When John Williams made two drafts for Indy's theme, one grand and regal and the other more subdued. Spielberg liked the grand one a lot and it became [[https://youtu.be/-bTpp8PQSog?t=6 the iconic theme]], but upon his suggestion, the subdued one was used for [[https://youtu.be/-bTpp8PQSog?t=37 the middle portion]].

[[folder:Live Action TV]]
* The shows ''Series/HomicideLifeOnTheStreet'' and ''Series/LawAndOrder'' , which had distinctive ways of sequeing from one scene to another[[note]](''Homicide'' had smash cuts and a sort of industrial whooshing noise, ''L&O'' cut to black with its trademark 'glun-glung' noise, followed by text explaining the time and place of the next scene as it faded in.)[[/note]], crossed over once. During the crossover, the scenes in UsefulNotes/NewYorkCity (''L&O's'' turf) were filmed with ''Homicide's'' transitions, and those in UsefulNotes/{{Baltimore}} (''Homicide's'' setting) had ''L&O's'' transitions. (That is: Cut to black, glun-glung, text: "Baltimore Homicide Division, 10:30 AM.", fade in.)
* Quite common in ''Franchise/SuperSentai'' teamups, with the team's logos merging. For example, ''Series/JukenSentaiGekiranger'' vs ''Series/EngineSentaiGoOnger'' ends with the Geki triple-claw emblem on top of the Go-onger "G" speedometer.
* ''Series/{{Arrowverse}}'' crossovers will often switch up the title cards and commercial-break scene wipes of the series involved. For instance, in the first two part crossover between ''Series/{{Arrow}}'' and ''Series/TheFlash2014'', "Flash vs. Arrow" had one of Ollie's arrows take the place of Barry's lightning bolt, and the reverse happened in "The Brave and the Bold".
* ''Franchise/KamenRider'', starting with ''Series/KamenRiderGaim'', has begun exploiting the SwissArmyHero trope so that during crossover movies and other special occasions, the Riders will gain special alternate forms that mimic the powers and appearance of other Riders.

[[folder:Professional Wrestling]]
* Sometimes two wrestlers forming a tag team will have their respective {{theme tune}}s and entrances "mashed up". Examples: Luger & Smith, the Allied Powers; Kane and Hurricane Helms as [=HurriKane=], or the Corporate Ministry (The Undertaker's "Ministry of Darkness" and Vince [=McMahon=]'s "Corporation" stables, merged) using a remix of the Corporation's theme in the style of the Ministry's theme.

[[folder:Tabletop Games]]
* The [[MagicTheGathering Guilds of Ravnica]] all have their own sigils, that are, abstractly, combinations of the mana symbols for their colors. For example, Selesnya's symbol, combines white's sun with green's tree to make a mostly circular tree with sunbeams coming out of it, while Rakdos's is a flaming skull.

* ''VideoGame/SonicTheHedgehog2006'': Mephiles has a sinister-sounding piano {{leitmotif}} (with a techno remix as his boss fight music). Iblis is accompanied by a bombastic, orchestral score. When the two fuse together to form the TrueFinalBoss Solaris, the phase 1 boss music is Mephiles' leitmotif, performed by Iblis' bombastic orchestra.
* The DS version of ''[[VideoGame/MarioAndSonicAtTheOlympicGames Mario & Sonic At The Winter Olympic Games]]'' has [[VeryDefinitelyFinalDungeon Blizland]], half of which represents [[Franchise/SonictheHedgehog Dr. Eggman's]] [[EternalEngine factories]] while the other half represents [[Franchise/SuperMarioBros Bowser's]] [[LethalLavaLand Castle]].
* In ''VideoGame/AngryBirds Franchise/StarWars'', the Alliance Starbird incorporates the omnipresent slingshot that the birds use, while a pig's snout is added to the Imperial crest.
* ''VideoGame/FreeSpace 2'' borrows the style for an early short video discussion backstory, showing the Galactic Terran Alliance and Parliamentary Vasudan Empire emblems merging into the Galactic Terran-Vasudan Alliance emblem. In general, the GTVA emblem counts as this trope just as much as the Union Flag does, being a combination of the symbols most representing the Terran and Vasudan peoples.
* A variant in ''Franchise/BlazBlue'': every character has a special "crest" that represents them (you can see them when they perform their LimitBreak or FinishingMove). One certain character's crest is a combination of two others'. [[spoiler:It's the Black Beast's, whose crest is a combination of Ragna and Nu-13's.]]
* ''Franchise/DragonAge'': The Inquisition symbol combines the "Eye in a Sunburst" of the Seekers of Truth and the "FlamingSword" of the Templar Order. Justified as both factions derived from the original Inquisition and apparently adopted their preferred aspect of the logo when they broke off.

[[folder:Web Original]]
* ''WebVideo/ToddInTheShadows'' does his [[CouchGag "playing the reviewed song" intro]] whenever crossing over with other reviewers from ''That Guy With The Glasses''. For example, he plays [[WebVideo/BadMovieBeatdown Film Brain]]'s "Ready to Roll" over the BMB opening sequence, "It Wasn't Me" after he and WebVideo/TheRapCritic accept to review the song, and [[Music/BritneySpears "I'm Not a Girl Not Yet a Woman"]] when he and WebVideo/TheNostalgiaChick review ''Film/Crossroads2002'' (though the Chick decides to join him at the piano).
* For WebVideo/TheCinemaSnob's crossover with ''WebVideo/BrowsHeldHigh'', the Snob's theme plays over Oancitizen's opening sequence.
* ''WebVideo/BadMovieBeatdown'' crossovers at times mix images of the guest reviewer in the intro, as well as a {{Portmantitle}} ("[[WebVideo/BrowsHeldHigh Brows Beat Down]]", "[[WebVideo/MikeJ Shameful Sequels Beatdown]]", "Bad Movie Beatdown [[Creator/AllisonPregler Presents]]").
* This is how the Meta symbol in ''Machinima/RedVsBlue'' was formed, out of the symbols of all the other AI's which are most of the Greek alphabet.
* ''Blog/AskTwixieGenies'': After Twilight moves into Trixie's bottle, the symbol on it shifts from Trixie's cutie mark to a subtle combination of Trixie's and Twilight's marks. This appears to be a magical feature of genie bottles; later on, when Trixie is taken from the bottle, the symbol shifts to Twilight's cutie mark.

[[folder:Western Animation]]
* The crossover between ''WesternAnimation/Ben10UltimateAlien'' and ''WesternAnimation/GeneratorRex'', ''[[WesternAnimation/Ben10GeneratorRexHeroesUnited Heroes United]]'', had Ben 10's Omnitrix at the center of Rex's gear logo.
* Similar to the above, the crossover of ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' and ''WesternAnimation/CodenameKidsNextDoor'' has the openings combined, making the KND operatives grow flesh from bone like the former's opening.
* In-universe example in ''WesternAnimation/TheSimpsons'', episode [[Recap/TheSimpsonsS8E22InMargeWeTrust "In Marge We Trust"]]: Merging the smiling fish logo of Matsamura Fishworks with the lightbulb logo of Tamaribuchi Heavy Manufacturing Concern, the two companies involved in the production of Mr. Sparkle dishwashing detergent, results in a grinning yellow head that just happens to resemble Homer's. "There's your answer, fishbulb."
* Nearly every Gem in ''WesternAnimation/StevenUniverse'' has a {{leitmotif}}, and when two [[FusionDance Fuse together]], the result has a theme that has elements of both components'. This is also used to form most Fusions' WeaponOfChoice. Opal, for instance, turns Pearl's spear into a bow with Amethyst's whip as the string.

[[folder:Real Life]]
* Quite common with national flags and coats of arms. The Union Jack was originally a combination of the flags of England and Scotland. Later, Ireland was added. [[AndZoidberg But not Wales]]. Wales was invaded. The others joined peacefully by acts of their parliaments, but a few [[UsefulNotes/TheTroubles problems]] arose.
* The Australian Coat of Arms includes a shield divided into six with the arms of each of the states on it. Originally they developed a unique federal arms, but they subsequently developed a new set including the arms of each state, inspired by...
* Canada's royal arms of the time (around 1910), which included the arms of each province. This however was terribly cluttered; Canada had at that point nine provinces, which was deemed to be too complicated to be useful. The Canadians then adopted the first form of their modern arms by taking the British royal arms, switching the extra England quarter with royal French fleurs-de-lys, adding three maple leaves on white in the base, and having the lion and the unicorn carry flagpoles bearing the Union Jack and a blue flag with fleurs-de-lys, respectively.[[note]]Among other changes; also, the "compartment", i.e. the "land" the supporters are standing on, contains intertwined roses (for England), thistles (for Scotland), shamrocks (for Ireland), and lilies (for France); the lion in the crest carries a maple leaf; and in the contemporary version, the mantling (the fiddly bits around the shield) is maple-shaped. The arms as a whole are arguably SigilSpam, since they contain ''six lions'' (three in the England quarter, one in the Scotland quarter, one as a supporter, and the aforementioned one carrying a maple leaf in the crest).[[/note]]
* Following UsefulNotes/WarsOfTheRoses, [[UsefulNotes/TheHouseOfTudor Henry VII]] created the Tudor Rose, which was the White Rose of the House of York within the Red Rose of the House of Lancaster, representing the merging of the two houses (His mother was of the House of Lancaster and his wife was of the House of York).
