->''This is the Ultimate Showdown of Ultimate Destiny\\
Good guys, bad guys and explosions, as far as the eye can see\\
And only one will survive, I wonder who it will be\\
This is the Ultimate Showdown of Ultimate Destiny''
-->-- Chorus

"The Ultimate Showdown of Ultimate Destiny" (sometimes shortened to simply "The Ultimate Showdown") is a song by Music/LemonDemon from his 2006 album ''Dinosaurchestra'', best known for its iconic WebAnimation created by Shawn Vulliez for Platform/{{Newgrounds}} a year earlier, which can be seen [[https://www.newgrounds.com/portal/view/285267 here]].

The song and AnimatedMusicVideo tell the story of [[MassiveMultiplayerCrossover dozens of (mostly 20th century) fictional characters, historical figures and celebrities]] [[LetsYouAndHimFight duking it out]]. It starts with ComicBook/{{Batman}} trying to stop Franchise/{{Godzilla}} from destroying UsefulNotes/{{Tokyo}} before both are stopped by Creator/ShaquilleONeal, and just gets crazier from there.

The song would prove to be Lemon Demon's BreakthroughHit, repeatedly topping the Funny Five on ''the Creator/DrDemento {{radio}} show''. In 2010, Lemon Demon would release [[https://www.youtube.com/watch?v=mXwJxtHasYg a new version of the song]] for the VideoGame/RockBand Network.

For the [[MilestoneCelebration 15th anniversary]] of the original animation's posting, Blabberdookie and Warddraws hosted a MultiAnimatorProject to create a new version of the original video, set to the RBN Mix. On October 22, 2021, the end results of this effort was released, [[https://youtu.be/hGtbr-ZvdT0 which can be found here]].

!!The song and animation have examples of the following {{trope}}s:
* AgonyOfTheFeet: In the animated video, one of Godzilla's feet is wounded by a Bat Grenade. The kaiju clutches his wounded foot in pain while hopping on his other feet.
* AnimatedMusicVideo: For the Music/LemonDemon song.
* AdaptationalBadass: Several "normal" celebrities and characters, like Shaquille O'Neal and a zombified UsefulNotes/AbrahamLincoln are suddenly capable of going toe to toe with Godzilla and Batman. [[spoiler: The crowning example of this is Mr. Rogers, who outlasts everyone and wins the titular battle.]]
* AtopAMountainOfCorpses: [[spoiler:Mr. Rogers stands victorious on top of a mountain of dead combatants in the battle as the song comes to an end. Even more noticeable in the redux animation]].
* BatmanGrabsAGun: Literally! After being badly injured, Batman resorts to stealing Indiana Jones' gun and shooting at the other fighters.
* BloodyHilarious: When Chuck Norris crushes Batman's head in Vulliez's animation, it explodes in a shower of red goop.
* ChromosomeCasting: Apart from any females contained within the group of "every single Power Ranger," and ''possibly'' the Care Bear who attacks Abraham Lincoln and Creator/JackieChan, every combatant mentioned in the song and shown in the video is male, despite the amount of characters. Averted in the redux version, though.
* ChronicHeroSyndrome: [[Franchise/{{Transformers}} Optimus Prime]] spends more time saving others than defending himself, which ultimately leads to his defeat.
* CoolVsAwesome: It begins with Franchise/{{Batman}} taking on Franchise/{{Godzilla}} and only grows crazier from there.
* DecompositeCharacter: "Gandalf the Grey and Gandalf the White" are presented as different characters.
* DownerEnding: [[spoiler:[[EverybodyDiesEnding Everyone's dead by the end]], with Mr. Rogers being DrivenToSuicide. Though unlike other examples, this one is pretty lighthearted.]]
* DrivenToSuicide: [[spoiler:Mr. Rogers, who commits {{seppuku}} at the end of the animation, presumably from guilt over being the last survivor.]]
* {{Eyedscreen}}: Godzilla getting mad at Optimus Prime.
* EyesAlwaysShut: Franchise/IndianaJones doesn't open his eyes, even when Chuck kicks him in the crotch. He doesn't need to aim his whip.
* ForeverWar: Apparently, the fight rages on "for a century" [[spoiler:until Mr. Rogers is the only one left.]]
* GodzillaThreshold: Ironically, it isn't actually used to take down Godzilla despite him being in the fight. [[spoiler:A large group of heroes and villains have to team up to take down Chuck Norris.]]
* HeadCrushing: Upon Creator/ChuckNorris descending from the heavens and delivering a mighty GroinAttack to [[Franchise/IndianaJones Indiana Jones]], [[Characters/BatmanTheCharacter Batman]] attempts to disguise himself by undressing into [[SecretIdentity Bruce Wayne]]. Chuck sees through this clever disguise and crushes Batman's head between his thighs.
* LastSurvivorSuicide: [[spoiler:At the end of the animated Newgrounds video, Mr. Rogers, the winner of the showdown, commits seppuku.]]
* MassiveMultiplayerCrossover: The song name drops no fewer than 31 pop culture icons, both fictional and real, most of whom from the mid- to late-20th century. The Newgrounds animation features dozens more. The final verse alone introduces at least 19 characters (and dozens more if you take "every single [[Franchise/PowerRangers Power Ranger]]" as meaning ''every'' Power Ranger there has ever been). A full list can [[https://en.wikipedia.org/wiki/The_Ultimate_Showdown_of_Ultimate_Destiny be found on]] Website/TheOtherWiki.
* MemeticBadass: Creator/ChuckNorris' status as one is acknowledged InUniverse. He arrives on the battlefield by descending from {{Heaven}}, with his entrance being accompanied by an EtherealChoir, he manages to take out both Indiana Jones and Batman by himself, and it takes a large alliance of a lot of powerful (and some not-so-powerful) characters to take him down.
* PatterSong: As is to be expected for a song rattling off a long list of characters, Neil Cicierega manages to get [[MotorMouth an impressive number of syllables out in a few breaths]].
* Rule34: A porn parody called "The Ultimate Orgy," where the characters... ahem, "[[EveryoneHasLotsOfSex make love and not war]]," was created by a Newgrounds user named (appropriately enough) "NotSafeForWork", two years after the original.
* ShoutOut: A whole bunch during the chorus:
** [[Franchise/SuperMarioBros Mario]] [[FandomRivalry versus]] Franchise/SonicTheHedgehog.
** SantaClaus getting hit by [[Franchise/BackToTheFuture the DeLorean time machine]].
** A [[Franchise/StarWars Jawa]] [[GrievousHarmWithABody using C3PO to beat up R2-D2]].
** Creator/SamuelLJackson [[Film/SnakesOnAPlane getting tackled by snakes]].
** [[Website/SomethingAwful Lowtax]] punching Eric Bauman in the face.
** [[Series/ArrestedDevelopment Blue Man Tobias]].
** [[Manga/DragonBall Goku]] riding the Flying Nimbus.
* SingleTear: Indy sheds a single tear after Chuck Norris [[GroinAttack kicks him in the groin]]. The victor, [[spoiler:Mr. Rogers]] sheds one for the dead.
* StaringKid: The little kid with the ice cream cone, looking on "in total awe".
* StealthPun: Music/AaronCarter beats up Shaquille O'Neal. [[spoiler:[[https://www.youtube.com/watch?v=OfhhWA9GF0M That's how he beat Shaq]]]].
* SuperReflexes: Creator/JackieChan is able to deflect a bullet with his fist.
* ThereCanBeOnlyOne: The chorus states "only one will survive". The Ultimate Showdown, in fact, does goes on until only one combatant is left standing, [[spoiler:with Mr. Rogers emerging the {{sole survivor}} and the victor of the showdown]].
* TwoDecadesBehind: While there are plenty of references to 2000s pop culture (like Gandalf appearing as he does in Peter Jackson's ''Film/TheLordOfTheRings''), the majority of references are to pop culture from the '70s, '80s and '90s, like ''Series/PeeWeesPlayhouse'', ''Series/MisterRogersNeighborhood'' and actor Creator/ChuckNorris as Series/WalkerTexasRanger.
* UngratefulBastard: Franchise/IndianaJones saves Batman's life from UsefulNotes/AbrahamLincoln. As thanks, Batman steals Indy's gun and tries to shoot at the other fighters. [[AvertedTrope Averted]] in this [[https://www.youtube.com/watch?v=BIGqfnKgf80 sprite-animated version]], where Jones attacks Batman after tripping Lincoln, meaning he wasn't saving Batman here, but he and Lincoln were just in his path.
* UltimateShowdownOfUltimateDestiny: [[TropeNamers Where do you think the name came from]]?
* VictoryByEndurance: Implied to be how [[spoiler:Mr. Rogers]] won.
* WhatHappenedToTheMouse: In the video, the [=DeLorean=] time machine time travels away after running Santa down, and we never see it again.
----
!!The 2021 redux animation has examples of: (Spoilers)
* ActorAllusion: Among the scenes of various characters fighting near the end, [[{{Franchise/Halloween}} Michael Myers]] is killed by Film/AustinPowers, who is played by actor Creator/MikeMyers.
* AdaptationExpansion: The redux animation at times goes into more details than the original. One of the more noticeable examples is how more of Chuck Norris's defeat is shown.
** There are many more scenes of random characters duking it out, including many who didn't exist when the original animation was made, such as the version of ComicBook/DoctorOctopus from ''WesternAnimation/SpiderManIntoTheSpiderVerse'' replacing the normal one.
** The redux makes use of the RBN Mix, which repeats the chorus four times in increasing intensity, giving the animators ample opportunity to work in ''even more'' extra fighting scenes and cameos. Prominent examples include a scene in which [[WesternAnimation/RickAndMorty Pickle Rick]] gets stepped on by [[Manga/MyHeroAcademia Mt. Lady]] and one where [[Webcomic/MobPsycho100 Mob]] incinerates Franchise/{{Garfield}} and [[WesternAnimation/MyLifeAsATeenageRobot Jenny]]).
* BloodSplatteredInnocents: The kid with the ice cream cone gets blood splattered on his face the first time we see him now.
* {{Bowdlerize}}: Sort of, but ultimately for a less controversial manner. During Robin's cameo 'before [Batman went] back to the Batcave', he's portrayed to be in his full suit dozing off on the couch, instead of just his undies (formerly to poke fun of the {{homoerotic subtext}} between the Dynamic Duo in the Silver Age, which wouldn't fly in the modern era).
* TheCameo: [[VideoGame/FridayNightFunkin Boyfriend and Monster]], the latter ([[CommonKnowledge incorrectly]]) assumed to be a reference to Lemon Demon, appear on posters at one point.
* DefiantToTheEnd: Jenny goes down trying to shoot at Mob.
* DropTheCow: Among the scenes of various characters fighting near the end, Creator/GabeNewell drops onto [[VideoGame/PunchOut Little Mac]] and [[Franchise/StreetFighter Ryu]], leaving a massive crater.
* GainaxEnding: In the final scene, Mr. Rogers, having stabbed himself... abruptly stands up and dances the running man. He then [[VideoGame/{{Fortnite}} flosses]] and does the Carlton and the Peanut Butter Jelly Time dance before flying into the sky and exploding in a shower of gore, with a smile on his face.
* GenderEqualEnsemble: not ''quite'' equal, but averts the original version's ChromosomeCasting by adding several female characters.[[note]]Samus from ''Franchise/{{Metroid}}'', singer Music/BillieEilish, WesternAnimation/RubyGloom, Princess Bubblegum from ''WesternAnimation/AdventureTime'', Ariel from ''Franchise/TheLittleMermaid'', Mount Lady from ''Franchise/MyHeroAcademia'', and Jenny XJ-9 from ''WesternAnimation/MyLifeAsATeenageRobot''.[[/note]]
* KillItThroughItsStomach: Among the scenes of various characters fighting near the end, [[WesternAnimation/FatAlbertAndTheCosbyKids Fat Albert]] drinks [[WesternAnimation/AquaTeenHungerForce Master Shake]], seemingly killing him, but his own stomach explodes immediately afterward.
* PowerFloats: In the redux animation, Shaq is now capable of this when he confronts Godzilla.
* RuleOfThree: [[WebAnimation/{{Tankmen}} Sergeant John]] appears three separate times, the first time alongside other ''Platform/{{Newgrounds}}'' characters, and twice more punching the [=YouTube=] logo in the face.
* RunningGag: Franchise/{{Superman}} is consistently portrayed as [[Creator/NicolasCage the version of the character]] from the unproduced film ''Superman Lives''.
* SceneryGorn: Jomun's take on [[spoiler: Mr. Rogers committing suicide]] has him ''surrounded'' by corpses.
* ShoutOut[=/=]TheCameo: [[ReferenceOverdosed Too many to list this time!]]
* SparedByTheAdaptation: Subverted. Optimus Prime originally died by getting his head bitten off by Godzilla, but when Abraham Lincoln tried to polefault on him (eventually clashing with Jackie Chan before getting hit with a Care Bear Stare), [[UnexplainedRecovery Optimus Prime is shown alive and well, with his head and all, meaning he survived Godzilla's chewing]] [[WeCanRebuildHim (Or got rebuilt in time to rejoin).]] However, it's also implied that he'll eventually die with the rest so Mr. Rogers will still be the only survivor.
** Likewise with the above, Jackie Chan survived the Care Bear stare as he's seen trying to resume his duel with Shaquille O'Neal when Chuck Norris arrives at the scene.
* SphereOfDestruction: [[Manga/MobPsycho100 Mob]] makes one against [[WesternAnimation/MyLifeAsATeenageRobot Jenny]] and [[ComicStrip/{{Garfield}} Garfield]].
* TrampledUnderfoot: Among the scenes of various characters fighting near the end, [[WesternAnimation/RickAndMorty Pickle Rick]] gets squashed by [[Manga/MyHeroAcademia Mt. Lady]].
