The 4Kids dub was already a joke for, among other things, cutting out a story arc involving a whale named Laboon, and another involving giants. Two later arcs that came up about 200 to 300 episodes later involved plot points based on those stories. The first one involved a character being friends with the two giants from the missing arc, and, in the second, the author introduced a new crewmate, Brook, whose entire character motivation revolves around getting back and seeing Laboon.
A voice-acting related one. Brook's VA, Yuichi Nagashima way before being known as Brook, voiced a character in the gag series Sexy Commando Gaiden named Tsuyoshi Tsobe also better known as Kyasharin or "Living Bones".
Also a voice-acting related one; the protagonist himself, Luffy's VA (Mayumi Tanaka), is voicing a villain in DokiDoki! Precure, the little boy Ira. The hilarious part? Eiichiro Odaconsiders the entire Precure series as his rival because his daughters love it more than his series. The fact that Luffy's VA is voicing a villain also adds the hilarity.
Real Account is a horror manga set where the characters is pulled into the social network app of the same name. It gets get both frightening and bloody hilarious when Nintendo announces their first social networking app Miitomo which has strangely many similarities to ReAca…
For more hilarity, guess which character is voiced by Tomokazu Sugita (the voice of Kyon)? Ronove the butler, who is also caught (sorta) into said "Groundhog Day" Loop. Not only everyone is Itsuki for Kyon, but now everyone is Ronove for Battler.
In episode 145, Yamagishi, the young balletmaster, tells Fish Eye that he had always wanted Kiriko for the lead in his production of Giselle because she's able to convey a wide range of emotions, unlike Fish Eye, who risks coming across as one-dimensional. You know, like most every Albrecht in productions since the Commies took over in Russia. If she lived in the days of Rudolf Nureyev, Kiriko would be a perfect partner for him.
Sailor Pluto always carries a staff tipped with a heart-shaped gem. In 2015, the New Horizons probe finally reached Pluto, and revealed two geological regions that, together, like a heart when seen from space.
The live-action part of the Toon Makers pilot of Sailor Moon that never aired received a great deal of criticism for taking the original anime and turning it into a Power Rangers knock-off. This was already funny given that Sailor Moon was always openly an all-female take on the popular Super Sentai franchise which spawned Power Rangers in the first place. It becomes funny in hindsight when you fast forward to 2004, when Toei literally made a tokusatsu of the show in the style of Super Sentai with Pretty Guardian Sailor Moon. They even included many seasoned veterans of the Super Sentai franchise in the production side of things, bringing the reference loop full circle.
The Brazilian Portuguese dub of Sailor Moon became infamous as the second season onwards had a cast completely different than the 1st season cast. The title character, that was voiced by Marli Bortoletto, was later voiced by Daniella Piquet in the other seasons. Later, when Cardcaptor Sakura started to air in Brazil, Piquet voiced Sakura, but when the second film premiered in the country, the same Bortoletto who voiced Sailor Moon first, replaced Piquet as the voice of Sakura. This movie actually has two different dubs, and both of them with the same voice actress.
In Kanon (2006), Yuichi is chastised for having a boring introduction to his new class. Yuichi says, "If's there an interesting way to introduce yourself, I'd like to see that." Earlier that same year, his voice actor had landed the role of Kyon.
Yuichi is also once called out for talking narration to himself by Kaori, something that Kyon does all the time.
Shugo Chara! had this weird moment where our resident crossdresser makes a return. Apparently, if Kukai, Tadase and Nagahiko were in the same scene, they would resemble the trio from Boku no Pico.
Mahou Sensei Negima! had a scene with Nodoka being attacked by a perverted bounty hunter with tentacles, who starts stripping her clothes off while ranting about "boobies". After Negi saves her in a Big Damn Heroes moment, the group later runs into the same gang of bounty hunters in a Bath house. Turns out the tentacle guy is actually a hot female with a healthy appreciation for breasts.Skinship Grope ensues.
Waaaay back in chapter 15, some eavesdropping caused the class to think that Negi was a prince. Roughly 200 chapters later, it turns out he is.
Also in chapter 210, after everyone important has left for the magical world, several characters are joking with the twins about how the main cast was abducted by aliens. The twins panic, saying "next time we meet Asuna she won't be Asuna anymore." Turns out not long into the arc, Asuna gets kidnapped and replaced with a lookalike that has her personality and memories.
And speaking of aliens. One of the major reveals later is that the magical world is based off Mars. This also happens to shed some light on Chao calling herself a Martian.
In Chapter 229, when they find out that Fate's real name is Tertium, which means the third, they start to worry if there's more then one of them. Come Chapter 311, and we meet Quartum, Quintum and Sextum.
The English dub of spinoff series Negima!? has a point where Shichimi says "Perhaps it is time to dine, nya" a paraphrase of Enma Ai's catchphrase from Hell Girl. It's even more hilarious when realizing that the joke was simply a Shout-Out in the Japanese version. In the dub it's a Shout-Outand a "same voice actor" joke, since Brina Palencia voices both characters.
One of the episodes of Soul Eater features a throwaway gag about how, since Shinigami-sama's soul is bound to Death City, the city would have to sprout legs and walk if he were to track down and defeat the Kishin, who has now gone into hiding. Cue episode 47 of the anime. While this might sound like Foreshadowing, the same scene appearing in the manga, which lacked the eventual plot twist.
In His Coool Seha Girls, Dreamcast suggests a version of Phantasy Star Online 2 where the players' equipment is replaced with puyos. Sega had already implemented such a feature in the game, with promotional items that turned the players' MAG into either a green or red puyo.
In a bonus feature in volume five it shows that one of Ed's boxers' possible designs was Automail. In a volume 7 bonus feature, guess what the Truth takes from him.
Kind of a weird example of both Fullmetal Alchemist and Cowboy Bebop with the latter's episode Sympathy for the Devil. The Bebop episode features a character, Wen who essentially looks identical to FMA's Selim Bradley. This is funny because of the common twist that both characters are far older than they look and are only masquerading as children. While probably accidental, it means that if you watched Bebop after FMA, you'd probably guess the twist immediately, and vice versa.
Rewatch episode 19 knowing that Mustang and Lust are married.
In the 2003 anime version, episode 15, Maes Hughes (voiced by Sonny Strait in the dub) says something along the lines of "What do you want me to do, fire my slingshot at him?!". Flash forward to 2007, and his voice actor became the new voice of the One Piece sniper Usopp...
Also from the 2003 anime: Selim Bradley is introduced at the last second only to be killed off by the anime's version of Pride, King Bradley. Four years later, Selim Bradley turns out to be the manga's Pride. And King Bradley is his direct subordinate.
A similar case comes even later with Scar's death in the 2003 anime, where he continues to fight even after having his arms blows off. Come chapter 105 of that manga and not only does Bradley do the same thing, it was caused byScar.
There is a filler episode with Mustang's subordinates getting creeped out by unusual things happening in Warehouse 13, several years before SyFy had a show called Warehouse 13 about unusual things happening.
In the Shippuden dub, Chiyo is voiced by Barbara Goodson. Her grandson, Sasori is voiced by Johnny Yong Bosch. That's right, Rita Repulsa and Adam are doing role reversal (Goodson as one of the heroes, and Bosch as a villain).
There's also the joke when Choji sees Naruto's Rasenshuriken and assumes, based on the name, that it was a projectile attack (it isn't). Nearly one hundred chapters later, it shows up again and now it is.
Naruto the Movie: Road to Ninja is the newest Shippuden movie set in an alternate universe (or something), the difference? Naruto's parents are alive and Sakura's are dead. Now remember that comment Sakura made in the beginning of the series about Naruto and his behavior because of a lack of parents and it turns into Gallows Humor.
Back in the first chapter/episode, Naruto is doing graffiti all over the Hokage Monument. One of them is his dad.
Chapter 599 revealed that Obito is the Big Bad Tobi, while in the English dub Obito was voiced by Vic Mignonga who also voiced "serious Tobi" in one of the video games. Consequently, Tobi might not be a good boy now, but he once was one.
In the preview for episode 25 attached to the end of episode 24, Naruto is freaking out over Part 1 of the Chuunin Exams, worried that he'll be "the oldest living Genin". As of now, Naruto's still a Genin and it looks like he's gonna stay that way. Not that it really matters.
In one Omake, Sakura calls out the staff because the current ending only features Hinata. The omake ends with her angrily demanding her own ending - which she got for the very next ending.
Naruto's fight with Gaara has him and Gamabunta due a joint transformation into an image of the kyuubi, though just to use its tails and claws for gripping. During the Fourth Shinobi War arc, Naruto gains the ability to turn into the real thing.
Akira Ishida (Gaara of the Desert's Japanese VA) is the defacto voice actor in Japan for Luke Skywalker. Luke was raised in Tatooine, a desert planet. Also overlapping with Relationship Voice Actor, Hiroshi Iwasaki (Shukaku's Japanese VA and Gaara's Tailed Beast) is also the defacto Japanese VA for C-3PO in the same franchise. Extra hilarity both Shukaku and C-3PO are the opposite of each other. Even more hilarious is the fact Gaara's life is basically what could happened if Luke was raised by his father Anakin aka Darth Vader, rather by his uncles and killing (a resurrected) Vader by himself, rather than Emperor Palpatine.
Tessho Genda's role as the Kurama The Nine-tailed Fox is pretty hilarious if you take into account he voiced some roles with some odd relation with him voicing a giant-sized fox.
As Kratos in Japanese: Kratos' main speciality is killing creatures like Kurama for breakfast, and that's before going against gods.
Richard Steven Horvitz had a small recurring role in Duel Masters as Fritz the bitter goblin. One of his main running gags was his Berserk Button, where he would yell at anyone who called him a squirrel. Thus, fans of the dub were amused when Horvitz was later cast as the titular animal character in Squirrel Boy.
When the mysterious black cat, Yoruichi, first appears in the story, the English dub has Urahara greet it with an enthusiastic "Who's my favourite pussy?!". Later on in the story, it's revealed that the black cat is really a shapeshifting woman.
In a joke slice-of-life sketch, Iemura, 4th Division third seat, and self-confessed weakest third seat in the entire Gotei 13, complains about someone like Kyoraku becoming captain and outranking him, who, despite his lazy, womanising behaviour was pushed into the Gotei 13 to prevent his prodigious talent from being wasted. He's talking about the future Captain-Commander of the Gotei 13.
Early in the Lost Agent Arc, Uryuu is mistaken for Ichigo. During a close-up of Uryuu's face, he demands "You got a good look at his face, didn't you? So what part of me resembles Kurosaki?". Since Kubo uses Only Six Faces, the fanbase quickly transformed it into a meme. Kubo later reveals that Ichigo and Uryuu are blood relatives; Ichigo's mother and Uryuu's father were cousins.
Anyone who's familiar with Pokémon's "aim for the horn" probably had their laughs back in Gen III of the games, when the Rhyhorn family (including Rhydon, which was the victim of said move) gained the Lightningrod ability. So not only is it immune to electrical attacks, probably to the frustration of those who can't tell between anime plot and game mechanics, but with that ability, as long as it's on the field, you can't aim an Electric attack at any other Pokémon!
Related to this, in the episode Tag! We're It...!, the first pair of opponents Ash and Paul face had...a Magmar and Rhydon. And the Rhydon had Lightningrod.
In the original anime, you aim for the horn. In Pokémon Origins, horn aims for you! Rhyhorn gets back at Electric-types by delivering a One-Hit-KO Thunderbolt to Red's Jolteon. Jolteon gets VoltAbsorb in Gen III.
Another bit regarding Lightningrod. Even though Ash's Pikachu has Static, he balanced on his tail to dodge a berserk Thunder from Surge's Raichu. As of Gen V, the Pikachu family has Lightningrod as their Dream ability.
Misty: You're not mature enough to understand. Ash: I am too! Misty: Well, someday you'll grow up. Ash:I already amgrown up!
In 2006, there was an April Fools joke pulled by a Japanese fansite about an anime adaptation of the Pokémon Mystery DungeonSpin-Off games. Later in the fall of that year when when the games made their American debut, Cartoon Network did air an anime adaptation alongside it.
In the third episode of the anime series, "Ash Catches a Pokémon", when Jessie and James both unleash their Pokémon at once, Ash states that using two Pokémon at once is against Pokémon League rules. Come 2002, upon the release of Ruby & Sapphire, Double Battles and Multi Battles (also known as Tag Battles) are introduced.
Not necessarily hilarious, but the Viridian Gym battle with Jessie saw her send out three Pokémon at once against Ash's three. It would take four generations for triple battles to be officially introduced to the game.
There's also a scene where Ash makes a remark about how Shellder clamping on Psyduck's tail would make it a Psybro due to how Slowpoke evolves into Slowbro. In the same episode, Shellder clamps onto Psyduck's head. Guess how Slowking evolves from Slowpoke.
Ash's Pikachu has the Fan Nickname "Godchu" for being seen as overpowered, including the aforementioned "Aim for the horn" incident. Come Super Smash Bros. 64, Pikachu (although it's obviously not Ash's) was found to be top-tier.
Contrast with Mewtwo. "We dreamed of creating the world's strongest Pokémon...and he's bottom tier in Melee and MIA in Brawl."
In one episode, Ash inadvertently interrupts Trip while he battles a Palpitoad, causing the Pokemon to run away before Trip could catch it. In the next episode, Ash ends up catching a Palpitoad for himself.
This is reminiscent of an incident in "Challenge of the Samurai." Samurai interrupts Ash, who's trying to catch a Weedle, and the Pokemon escapes.
In "The Mystery of the Lighthouse," Bill remarks that there are more Pokémon than one can imagine, and it will take years to find them all. The episode aired in Japan in 1997. Fast-forward 15 years, and Pokémon is one of the longest-running TV shows ever in excess of 700 episodes, 15 movies, and one of the most popular video game series ever with no signs of slowing down.
And in that time, the series has introduced another five hundred species of Pokémon.
In the episode "Holiday at Aopulco," the Who's That Pokémon?, a eyecatch bumper showing a different Pokémon each time, turns out to be Brutella, the main villain of that episode. 15 years later, in episode 10 of the anime Smile Pretty Cure!note the episode where the villains go to the human world for Akane's okonominayaki, the second eyecatch (usually showing the team mascot Candy one being a different outfit or background) turned out to be the main monster of the series, an Akanbe!
It's also worth noting that this kind of Who's That Pokémon? happened again in the Japanese version of "The Bug Stops Here!", with Jessie as a Venomoth. The Akanbe kind of eyecatch in Smile Pretty Cure! happened twice during the first half of the series, appearing again 7 episodes later, because the episode was about a joke contest.
In "Minccino: Neat and Tidy", Bianca tells Ash's Oshawott to use Hydro Pump, with Ash replying that he doesn't know it. Oshawott would later learn Hydro Pump in Best Wishes 2.
Way back in the first season episode "The Flame Pokémon-athon", there's a race where trainers ride their Pokémon, and one trainer is riding a Rhyhorn, which given the variety of Pokémon that can be used is shown to be not such a good choice, especially when there turns out to be a river crossing and Rhyhorn sinks like, well, a giant stone rhinoceros. Flash forward five generations and Rhyhorn racing is a serious Kalosian sport.
In a Kanto filler episode dealing with the theory that Clefairy came from space, there's a joke scene where a Mad Scientist invents a scanner that claims Clefairy, Jigglypuff and Misty (who was holding Togepi) are aliens. All three Pokemon would end up becoming Fairy Types 6 generations later. That scientist accidentally discovered a new type!
Ash's first Pokemon League battle ever takes place over a pool of water, and at one point, he orders Krabby to dive into it. Come Gen III, Dive becomes an official move.
It's honestly quite astounding how the writer of Pokémon Special makes up so much of his story yet nearly all of it still manages to fit into future game canon. This is why fans joke that Hidenori Kusaka can see into the future:
In the Yellow arc, there's a flashback of Oak's Kangaskhan beating one of Agatha's ghosts with a Dizzy Punch, which should be a total cop out seeing how Normal moves don't affect Ghosts. Now about a decade later in the newer games, Kangaskhan is given the ability Scrappy...which allows Normal (and Fighting) attacks to hit Ghost-types.
The new "critical capture" feature in the Black and White games sound a lot like capture spots.
So, you dress up as a Rocket member to infiltrate their base, only to have your cover blown because your disguise was ripped off... Special did it long before the HGSS games were released.
Zapmolcuno is finished off by a Blastoise, Charizard, and Venusaur simultaneously using their strongest attacks. It's the Triple Finish!
In Pokémon Platinum, you get the chance to purchase an insanely expensive villa and furnish it with insanely expensive furniture. Good thing that the lead character of the corresponding arc was conveniently already established to be insanely rich.
A green jewel meant to control Rayquaza... Emerald had one on his forehead before the HGSS games came up with the concept.
It took five generations for Game Freak to have the Gym Leaders more involved with the plot, have secondary jobs, and have them directly oppose the evil villainous team. It took only one for Pokéspe.
Black's Munna clearing his head is a reference to the C-Gear. There is now a Munna C-Gear skin available.
In the GSC arc, some Rocket grunts fill a Spider Web with electricity. Gen V introduces the move Electroweb.
In the Platinum arc, Caitlin's personal Pokémon is a Gallade. As it turns out in the BW games, she is a master of Psychic Pokemon.
Prowl in Transformers: Robots in Disguise is a strict police car Autobot who lives "by the book". In the English dub a year later, his voice actor was Wayne Lewis, who is a porn actor under the name "Wankus".
Remember that yacht that was from the delayed episode for School Days? It turns out that it is the yacht of the director of School Days, Keitaro Motonaga, and that the nature footage was taken during a TNK corporate retreat in 2005. Nice boat, indeed.
And when the episode was released later, it turned out that the final scene actually does take place on a nice boat.
Very early on Dragon Ball, when Goku turns into a giant ape for the first time, Oolong remarks "What's with this dude? Is he an alien?" About 15 volumes later... he is.
Similarly, when Goku and Piccolo Daimaô first square off, Piccolo calls Goku "smaller than ant's poop" and Goku replies by calling him "slug's poop". Slug in Japanese is "Namekuji", where the name for the later-introduced Planet Namek comes from. Guess who's from Namek? Piccolo.
When Bulma is first introduced in Dragon Ball, she planned on using the Dragon Balls to wish for a Prince Charming boyfriend. She ends up married to a Warrior Prince in Dragon Ball Z. It's even lampshadedhere in Dragon Ball SD.
We're all familiar with Dragonball Evolution, right? What about Dragon Ball GT Evolution? No? Back when Funimation were doing single disc releases of the series they did a form of Idiosyncratic Volume Naming involving words that end with "ion". "Evolution" was the volume with episodes 48-51.
Speaking of GT, the German dub of the series renamed the Black Star Dragon Balls as the Super Dragon Balls. Good thing GT isn't in the same continuity as Dragon Ball Super, otherwise the German dub would've had to rename the actual Super Dragon Balls the Black Star Dragon Balls.
Apparently, Mr. Satan invented planking about fifteen years before anyone else was doing it. In attempt to make it look like he had knocked out Majin Buu for a photo he was taking, he told Buu to hold still and lay flat on his stomach. He even commented that it seemed strange, but it was the new trend in picture-taking.
When Goku refuses to kill Piccolo Jr. after winning the fight against him at the end of Dragon Ball, stating that he could use a rival, in the Funimation dub Yamcha says sarcastically, "Oh, I'm sure you'll be best friends someday." Guess who actually does end up best friends with Piccolo in Dragon Ball Z? Goku's son.
One of the early antagonists in Dragon Ball was a rabbit who had the power to turn anyone he touched into a carrot. When Goku faces him, the rabbit asks him if he wants to be carrot. In Dragon Ball Z, it turns out that Goku's Saiyan name is Kakarot!
At one point during Goku and Krillin's training, Master Roshi tied them both to a tree, shook a hornet's nest with a stick, and told them to DODGE!
Tengen Toppa Gurren Lagann does this a few times, but in episode 4, Kamina says that 16 combines at once sounds "Stupid", but in Lagann-Hen, the second movie, this is almost exactly what Simon does, and turns into a giant energy reincarnation of Kamina, the same person who advised against this stupid stunt.
Kamina City actually exists, in Congo. It also has a badass motto, "To Take the Blazing Sun in our Bare Hands".
In the first episode of RahXephon, Haruka invites Ayato to come with her, saying she'll explain all the world's secrets. He responds that he's not interested in older women. Although this line is already amusing, it becomes much more so on second viewing because Ayato and Haruka actually do end up together.
In Hetalia, Japan's human name is Kiku Honda. When the Japanese soccer team later scored their first goal ever in a World Cup, the scorer's last name was Honda. Even being the most common Japanese surname, it's still funny.
It gets better: Kiku's name means chrysanthemum. "Chrysanthemum" is slang for "anus" in East Asian cultures... LOL, yaoi fangirls.
And then, even better: In Spain's version of Marukaite Chikyuu, you can hear Soccer/Football sounds, such as a ball being kicked and a referee's whistle being blown. Guess which national team won the 2010 FIFA World Cup?
In Part 7, one character has the ability to control a pack of raptor dinosaurs. That raptor packs can be trained to follow orders from a human is a central plot point of Jurassic World.
During a chase scene in an early episode of Trigun, Vash starts complaining to his maman, and then wonders aloud why he's speaking in French. Sort of random on its own, but hilarious when you consider who he ends up voicing in Axis Powers Hetalia...
The Prince of Tennis is a Shounen sports series, so naturally, many of the events are too far-fetched to be plausible. One match between Tezuka and Atobe leads to a 37-35 points tie-breaker. A later match between Atobe and Ryoma ends with a 116-114 points tiebreaker, implying a duration of several hours for the tiebreaker alone. But surely, no actual living person, let alone two people, have that much stamina, right?
In the fields of Latin American dubs, Irwin Daayán provides a really good one. His break-out role was male!Seiya Kou in Sailor Moon Stars... flashforward 12 years and have him playing another Seiya as a part of the two Saint Seiya dubs for the Hades Saga. El Oh El.
Since the Latin-American dub studios have similar actor pools depending on which country the series are dubbed, the Relationship Voice Actor trope brings up this more than once. One of the best examples is when Victor Ugarte was cast as Shinji from Neon Genesis Evangelion in both Mexican dubs, and his sister Gaby is cast as Rei Ayanami in the 2nd one. This sounds normal at first, but once you remember that Rei is his mother's clone and thus she is Shinji's sister in canon... sort of, the deal becomes absolutely hilarious. Even better... considering how that spoiler is in the It Was His Sled vein now, there's no way that such a Relationship Voice Actor bit wasn't intentional.
In an episode of Code Geass, Lelouch goes to Ikebukuro and Jeremiah comes to kill him. Sounds fairly straightforward, until Johnny Yong Bosch and Crispin Freeman got cast as Izaya and Shizuo, and all you can think about is whether Jeremiah is going to throw a vending machine at Lulu when he gets there. (For context, Durarara!! is set in Ikebukuro.)
After Euphemia chooses Suzaku as her knight, Cornelia calls her to scold her about it, saying that if she wants to change the system, she can do so if she becomes Empress. That happens toward the end of Nightmare of Nunnally, with Cornelia's approval.
Kallen's claim in episode 19 that Euphemia is a useless puppet princess of Britannia who can't make any decisions of her own. Episodes later, Euphie gets killed after being accidentally mind controlled and stripped of her free will. Could be considered Harsher in Hindsight too.
"Zero, you son of a bitch!"
In one episode of Bludgeoning Angel Dokurochan, Sakura watches the "Binkan Salaryman" with Shizuki and Dokuro, which is a movie about a guy that's pretty... sensitive to everything. This scene becomes slightly better if you've heard "Jizz In My Pants".
Death Note. Both of Light Yagami's voiceactors have one of these. First is that Swaile voiced a guy named Lan Hikari... Let's see... "Hikari" is the Japanese word for Light...
More importantly is Miyano's when voicing Kiba from Wolf's Rain, when confronting Tsume for the first time. Tsume lets Kiba know that he has issues with his killing, but Kiba replies, "What's wrong with killing?" Then, Tsume tried to explain that killing is against the rules for the city, and which word does Kiba use to describe those rules? ROTTEN! In addition, how many letters in Kiba's name have to be changed to get Light's world-wide alias?
He had a reverse example of this for Death Note as well. At one point, Ryuk refers to Light Yagami as "a worthy shinigami." Later, in Soul Eater, Miyano voiced a literal shinigami... albiet one obsessed with symmetry.
Brad Swaile voiced Quatre, whose name means "four" in French, and who goes on a rampage in Wing Zero destroying colonies. Quatre also hates killing people and is a dedicated pacifist.
Becomes even funnier when learning that the other Matsuda from the Japanese Olympic Team is a policeman, and takes a turn into Black Comedy once learned that this Matsuda's speciality is sharp-shooting with a 10 mm pistol.
An early arc in the Get Backers anime had the Recoverery service of Ban and Ginji doing battle against transporter Kuroudo "Doctor Jackal" Akabane, voiced by Shannon McCormick in the dub. In the machinima Red vs. Blue, McCormick does the voice for Agent Washington, who happens to be codenamed Recovery One.
The second anime series of Baki the Grappler, "Maximum Tournament", said on its opening "The lightning only struck me once, but gee...". In the manga series, one character was indeed struck by a lightning. And he justshrugged it off. Once, but gee...
At the end of the DVD Commentary for End of Evangelion, the commentators joke about the (un)likelihood of Eva 2: Electric Boogaloo. A decade later, the oddly-titled Rebuild movies are in full swing, and one of the most popular fan theories about them is that they are actually sequels to the original series.
The meme "Get in the damn robot" is often used as a Take That! towards Shinji's unwillingness to pilot EVA-01 (especially in the first few episodes of the series). Fast forward to 2017 with the latest spin-offLegend Of The Piko Piko Middle School Students where not only Shinji, but the rest of the cast refuse to get in the damn robots to play video games instead.
In January 2011, the Adult Swim forums temporarily changed their "Other Anime" section to be themed around Panty & Stocking with Garterbelt. A few months later in April, Funimation licensed P&S. The dub being broadcast on AS in the future almost seems like a shoo-in now...
Early on, the author Hatori Bisco stated that she couldn't see Haruhi and Tamaki ending up together. Guess how it ends.
A couple of months prior to Mobile Suit Gundam Wing: Endless Waltz being released in the US, someone MST'd a fansub of the three-part OVA version. One of the riffs regarding Duo's flashback in part two references a scene from episode 11 of the main series:
Crow: (as Professor G) But go ahead and tell everyone you are part of Operation Meteor. And here's a little speech to memorize so you can amaze Quatre with how similar your orders are.
Speaking of Gundam, the alloy that comprised said Mobile Suit was called Gundarium and was made with Titanium ore mined from the Moon named Luna Titanium.Fun Fact This alloy is still called Luna Titanium in After War Gundam X fast forward to 2011 and it has been discovered that there is up to ten times the amount of Titanium ore on the Moon than originally theorized, oh and it's denser and stronger than anything found on the Earth.
Another dub-related HIH: Remember this doujin? Now imagine Casca replacing Mami: they're both voiced by Carrie Keranen.
Not dub-related: April 21, 2011: Episode 11 of ''Madoka Magica' airs. Homura, having previously stolen a few truckloads of Type 88 antiship missiles from the JGSDF, fires them off at Walpurgisnacht. April 21, 2011: In Real Life, the JGSDF's 6th Surface-to-Ship Missile Regiment, which uses Type 88 missiles, is disbanded.
And yet another dub-related HIH: Hitomi Shizuki's Fan Nickname is "Green Mugi". And then, we have Mugi's English voice actress, Shelby Lindley, voicing Hitomi.
This fan video features a mash-up of Madoka set to the opening song of The World God Only Knows. This is twofold hilarious in hindsight, as the video was made well before the final arc The World God Only Knows which featured Mental Time Travel, also a major part of Madoka's finale, and also because of the fact that, in the Madoka movies, Homura eventually becomes an equivalent to the devil.
This is actually surprising to some people since Johnny Yong Bosch had worked with Funimation a few times in the past.
And now Mr. Solusod is playing the lead in Eureka Seven AO - that is, the son of the character played by Bosch.
Back in the fourth volume of High School D×D, Vali boasts to the protagonist Issei that the current red dragon-white dragon rivalry was unfair because Vali's from a privileged family by being a descendant of Lucifer, while Issei's the son of a common Muggle. He then wished that Issei was at least from a family with some background. Fast forward to Volume 12 where Issei's now the son of both Great Red and Ophis, two of the most powerful beings in this series by virtue of rebuilding his body because his old body has died thanks to an Achilles' Heel.
In Appleseed Ex Machina, the current must-have product in Olympus is the Connexus, which is basically a smartphone except you wear it as a headset rather than hold it. The first version of the iPhone came out the same year as the movie.
The Tenchi Muyo! manga collection book Sasami Stories has two yonkoma that fit this:
In one comic, the artist declares that Queen Misaki would be the breakout character for the third OVA series like how Washu was that for the second. She turns out to have a very big (if very short) part in it.
Another comic has Kiyone Makibi smacking Mihoshi with a hammer and begging her to just forget about her. Come the third OVA series, Kiyone is replaced with Noike and Tenchi's mom takes up Kiyone's name.
The story of AKIRA is in a backdrop of the 2020 Neo-Tokyo Olympics, and the said title character was apparently below the unfinished Olympic stadium. On September 9, 2013, Tokyo was selected as the host of the 2020 Summer Olympic Games.
In Slayers, a hooded man named Zelgadis offers Lina Inverse and Gourry Gabriev to join him in order to be paid for a statue he wants. Lina refuses because "you're the kind of person who I'd rather die than join up with." Zelgadis later helps them defeat the Big Bad of that season, and as of Slayers Next, is a main characters and and an official member of the Five-Man Band.
A handful of vehicles in Future GPX Cyber Formula, like Asurada, Ogre and among others, can shape-shift its aerodynamics to make the cars go faster in straightways. A few decades later, Formula One now has the drag reduction system (or DRS for short) in their cars, which has the same effect.
In an episode of the English dub of Sgt. Frog, a reality show team comes to Earth to film an episode of their show. Natsumi replies "I could be the next Miley Cyrus". Keep in mind that the show came out in the early 2000s. Obviously, that joke has gotten even funnier nowadays.
Back at the end of the 90's when Viz still published their English manga releases as monthly comics, at the end of one Dragon Ball Z issue in a letters column one reader says that they far prefer DBZ over Pokémon and Sailor Moon. Viz recommends the reader try Pokémon (since they had the English license to the manga as well as the home video rights to the anime) but agrees about Sailor Moon (which they didn't have the license for). Flashforward to 2014 and Viz now has the English license to the Sailor Moon anime.
With his fluffy hair, Kenji Ban, a minor character from HeartCatch Pretty Cure!, could be easily mistaken for a shounen anime character. Two years later, Yoshihiko Umakoshi, character designer for Heartcatch, went on to work on an actual shounen anime.
An early mistranslation ("volley", as in volleyball, accidentally being translated into "ballet" due to similar katakana) caused some fanon about Akane from Smile Pretty Cure! practicing ballet. Then Minami, who actually practiced ballet, came on the scene...
Nearly two full decades after Sailor Moon tried out for a role in Giselle, Go! Princess Pretty Cure lead character Cure Flora performed a selection from the ballet for a recital.
Speaking of Sailor Moon, something related to character design: in the figure skating episode, look very closely in the crowd during the first shot of the hopefuls auditioning to replace Janelyn as Misha's figure skating partner. One of them, a redhead in a black and pink tunic, bears a pretty major resemblance to one of the franchise's first heroines.
Also, the Keflings games.note Basically taking the idea of Eren Titan plugging the hole in the wall by having a clothed Titan help the 'humans' (Keflings) build their town by carrying and placing buildings!
There's also Shadow of the Colossus, a Japanese PS2 game where you travel on horseback through a massive wasteland, slaying giants by attacking their weak point.
A story about fighting giants after said monsters destroy a wall meant to protect humans from them, where the main character's last name is Jaeger? Sounds vaguely familiar.
The meme of Eren being scrawny and Levi and Mikasa being obscenely muscled because of Word of God confirming that they both weigh more than him. Come Chapter 53, we find out that Eren is actually very muscular, and just has a lean build that makes it easy to hide.
Reiner commenting on the Female Titan having a "nice ass", when he knows it's Annie.
Yu Shimamura, who voices Annie, also does the voice for the little excited boy Eren sees when the 57th expedition returns in Episode 22. This is somewhat really ironic when the reason they're all so broken down is thanks to the Female Titan, and then you have Annie's voice actress being the only cheerful one welcoming them back and admiring how brave they are.
The Ship Tease between Eren and Annie when both their Japanese seiyuus played subtle love interests in Guilty Crown, where Shimamura's character also happens to crystallize herself at one point in front of Yuuki Kaji's character.
The 10th opening of the anime showing Zeref and Mavis side-by-side counts, as the manga hadn't even gotten to the point where it confirmed Zeref and Mavis has a deep connection at the time.
The author of Daily Life with Monster Girl is a fan of Metal Gear Solid and included references such as Miia the lamia dressed as Snake (what else) and Rachnera the arachne cosplaying as The Boss. The manga later was made into an anime, and the episode including those references and others was broadcast on September 1, 2015... the same day Metal Gear Solid V: The Phantom Pain was released worldwide.
Episode 10 of the anime is titled "Everyday Life With D", referring to a death threat against the protagonist signed simply "D". Given that the episode features some of the raunchiest scenes that appear in the manga, one can recall what "The D" means in some circles...
Gintama, mixing this with Biting-the-Hand Humor, makes a joke in the middle of Season 2 that there would be a movie of its Benizakura arc. A fake trailer was shown, and the characters joked in-universe how Sunrise already has the track record of recutting and remaking their series into feature-length movies. After the first Gintama series ended, this is exactly what Sunrise would eventually do for the first Gintama movie.
In the original manga, after getting caught by Gomez trashing some robots, with the help of Tsuotmu, Birdy rattles off a Sailor Moon-esque speech (though the original manga does predate Sailor Moon). In the OVA, Birdy was voiced by Sailor Moon's seiyuu herself.
Shyamalan's death at the hands of Sayaka after the Ryunka complete possesses her is a lot more unintentionally hilarious to watch when you remember that their seiyuu, Kenichi Suzumura and Maaya Sakamoto, are now married, which also augments the No Yay undertones between those two characters
In the OVA series, Birdy is followed by someone who turns out to be a talent scout, thinking she could be a model. In Decode, Birdy has a disguise as one.
There's an episode in which a little girl who defends a boy from bullies at a refugee camp Tsutomu and his friends visit sparks a debate among the boys about whether it's humiliating to have to be saved by a girl. In Heat Guy J, an earlier work by Kazuki Akane, two of the important men have the following exchange:
You have to be saved by a woman? That's so pathetic.
It's not every day you get saved by an angel.
Yutaka Izubuchi served as the creature designer for the OVA adaptation. He would also serve as the creative producer for Decode.
In-universe example: In one instance Fiona is caught by one of Rosso and Viola's henchmen, who comments that she's cute and will be a "real knocker in few years." Come the timeskip in Guardian Force, we see he was right on the money.
Speaking of Takahiro Sakurai, he ends up voicing the blond and spiky haired character Bit Cloud. The show aired on 2001. Fast forward to 2002, after the release of the first Kingdom Hearts, Sakurai is now the official voice of Cloud Strife, another blond and spiky haired character.
