History HilariousInHindsight / DeathBattle

* Wonder Woman's actress, Creator/GalGadot, went on record saying that she believed Diana could best Thor in a fight, around the same time [[Film/WonderWoman2017 her movie]] came out. Creator/ChrisHemsworth, Thor's actor, would later agree with her. Months later, both were announced as combatants against each other. [[spoiler:Turns out they were right on the money.]]

** This matchup can now be recreated with Garra and Toph's addition to ''VideoGame/{{Fortnite}}, with Toph herself being available for 2,000 [=VBucks=] while Garra was tied to a Battle Pass.

* ''Ivy vs. Orchid'' came out only a few days before Double Helix revealed a sneak peak that Orchid would be in ''VideoGame/KillerInstinct'' for UsefulNotes/XboxOne.

* ''Zitz vs. Leonardo'' [[Recap/DeathBattleS05E15RoshiVsJiraiya isn't the last time]] [[AnimalMotifs a turtle and a toad]] goes up against each other on the show. [[spoiler:Nor is it the last time the turtle wins and tears the toad in half.]] Ironically, the fighting styles of the combatants using these motifs are reversed that time around, with the toad being a ninja while the turtle has a more direct combat style.

* Death Battle previews for the He-Man and Lion-O fight seemed to imply that Lion-O's ability to control cats would be used on Battle Cat, which had some fans complaining that Death Battle was essentially breaking its own rules to give Lion-O an advantage in their fight. Needless to say, the battle itself made quick work of that little issue.
** The fights starts because Lion-O took He-Man transforming Cringer into Battlecat as animal abuse. In 2018 ''ComicBook/HeManThundercats'' Lion-O attempts to transform Cringer himself. Same comic would also have Lion-O quickly come to the same conclusion as Wiz and Boomstick about He-Man being vastly stronger...and then just ask Sword of Omens to give him "[[SuperMode strength beyond strength]]", briegly becoming He-Man's physical equal.

** Even more so, Kirby [[spoiler:defeated Buu despite being considered the underdog of the fight. Then the "World of Light" trailer for ''VideoGame/SuperSmashBrosUltimate'' shows Kirby surviving the annihilation of the ''Smash'' world while deities like Palutena and Rosalina or god-slayers like Shulk and Bayonetta weren't as fortunate.]]

** Goku fighting using Super Saiyan God in the Artic. [[Anime/DragonBallSuperBroly Sound familar?]]
* In ''Hercule Satan vs Dan Hibiki'', one of Hercule's capsules contains [[Anime/KillLaKill the Scissor Blade]]. Come Season 8, Ryuko Matoi would fight in this show.

** [[spoiler:In ''VideoGame/MarvelsSpiderMan2'', and there's something really funny about the eventual Venom vs Kraven fight halfway through the game, where the latter can be seen as a stand-in for [[EmpoweredBadassNormal Bane]], along with Venom (the victor) chomping off the head of Kraven (the loser).]]

* Less than three weeks after appearing in a battle against Frank West, Sony would announce that a remake of Leon Kennedy's debut game, ''VideoGame/ResidentEvil2'', was in development. Not only that, but for added hilarity, the remake was released within a few days of yet another highly-anticipated title: ''VideoGame/KingdomHeartsIII''. Both of their protagonists - Sora and Leon - not only appeared in back-to-back episodes [[spoiler:but won both of them handily.]]

** The art improvements mentioned under ''Luigi vs. Tails'' would come full circle with the release of Mario and Sonic's rematch, which ''was'' created by dedicated animators and featured truly ''fantastic'' visuals.

* Speaking of ''Ben 10 vs Green Lantern'', [[spoiler: fans who still don't like the way Ben was handled and killed will get some catharsis when Hal was just as brutally killed in ''Justice League: Apokolips War''. Bonus points for the Paradooms holding onto his hand that had the ring, his primary weapon, to prevent him from attacking before killing him, exactly how he defeated Ben.]]
** Remember Hal's iconic line before murdering Ben, "Time, huh? Thanks for the tip."? Well, in WesternAnimation/Ben102016, another Alien X (Who coincidentally was attacking Ben to get his Omnitrix) is greeted with Alien Force Ben mockingly telling him, "Thanks for the tip", and then shortly after that the invading Alien X is defeated.

** The ''Dragonzord VS Mechagodzilla'' fight was released on September 4th on Youtube, by sheer coincidence, it was also the birthday of one Creator/JasonDavidFrank, who played Tommy in the original Power Rangers. [[spoiler: Many tweeted Ben saying they really must have hated Power Rangers for the Dragonzord to lose on Jason's Birthday]].

* Similarly to Captain Marvel, The Hulk is a Marvel character [[spoiler:who dies twice, both from decapitation and by being blown up or vaporized, and loses to both DC and ''Dragon Ball'']].
** Even funnier is that [[spoiler:in Season 3, Hulk was killed by Doomsday, who is famous for having killed Superman, who killed Broly's fellow Saiyan Goku ''twice'' in Seasons 1 and 2. By killing Hulk, Broly's managed to outdo Goku himself.]]

** The first fight between Link and Cloud was released three years before the latter was revealed in ''VideoGame/SuperSmashBros'' If one takes the tier lists for [[VideoGame/SuperSmashBrosForNintendo3DSAndWiiU the fourth game]] into account, it is identical to the outcome of the rematch, [[spoiler:as Cloud defeats Link this time.]]

* Tanjiro's first encounter with a Demon Slayer was Giyu Tomioka, who's voiced by Creator/JohnnyYongBosch. Now he's facing off against another monster hunter with the same voice (from the source material).

** [[spoiler: Michael Myers' defeat would have further concrete evidence in Film/HalloweenEnds, where he's bled out and mutilated before being thrown into a junkyard shredder and reduced to mulch.]]

* "Frieza Vs. Megatron" would be once again, you guessed it, a matchup that Brandon Yates had done a fan commission prior to it's release, this one being "Deceptive Tyrants" released on November 10, 2020. ''Transformers One'', set for a September 2024 release, was also announced near the end of 2023.

** Furthermore, the song used in Spawn's reveal trailer, "Scattering the Ashes", has lyrics talking about a father and son's struggling with each other; aside from the song's title, this is pretty much the synopsis of the latest ''God of War'' game.

** The day Sephiroth was announced for ''VideoGame/SuperSmashBrosUltimate'' and the day Vergil is finally made available as DLC for ''VideoGame/DevilMayCry5 Special Edition'' are in such close proximity to one another that it almost cannot be coincidence.

* "Frieza Vs. Megatron" would be once again, you guessed it, a matchup that Brandon Yates had done a fan commission prior to it's release, this one being "Deceptive Tyrants" released on November 10, 2020.

* Before "Rick vs. The Doctor" released, it was confirmed that out of the last two matchups, one will be a controversial choice, leading many to believe said choice was [[Manga/JojosBizarreAdventureGoldenWind Giorno]] vs. [[VideoGame/Persona5 Joker]]. While the controversial matchup was revealed to be a reboot of "Goku vs. Superman", Xander Mobus, Jokers official voice actor, is slated to play the Man of Steel as revealed by the preview.

** Near the climax of the fight, a new Rick bursts out of the Doctor while he was regenerating. A few weeks after the fight was released, the 15th Doctor would literally split apart from the 14th Doctor during the latter's [[https://www.youtube.com/watch?v=ACYdbadw1fA regeneration]] in the 60th Anniversary special. Also helps that both the Death Battle & the 60th Anniversary special featured the David Tennant version of the Doctor regenerating.

* In most cases, a Marvel character whose ''Franchise/MarvelCinematicUniverse'' counterpart died at some point, even if they were brought back [[spoiler:survived their Death battle]], and vice versa. The only exceptions are [[spoiler:Hawkeye, War Machine, Quicksilver, Dr. Strange, Thanos, and Scarlet Witch]].
