Top 10 Craziest Anime Crossovers You Won’t Believe Actually Happened

Top 10 Craziest Anime Crossovers You Won't Believe Actually Happened

Anime may be fun on its own, but often creators plan to combine two series, creating an entertaining and unbelievable experience for fans. In every TV-watching home, crossovers are a special occasion. As much as you refuse to admit it, as a hardcore Otaku, you always yearn for the good old crossovers. Anime crossovers are something of a fading sub-genre these days, but back in the 1990s, when anime was at its peak, major studios would sometimes produce some of the most bizarre anime universe crossovers. Miniseries featuring badass action with the best shounen characters or just a plain rom-com piece that gets better with all of your beloved Shoujo characters gathered in a single show are typical examples. A few manga series have now followed this theme. Let’s look at a few anime crossovers you won’t believe happened.

1. Dream 9 Toriko & One Piece & Dragon Ball Z Super Collaboration Special (2013)

Dream 9 Toriko & One Piece & Dragon Ball Z Super Collaboration Special (2013)

Dragon Ball Z made a comeback on television as part of the Dream 9 Toriko & One Piece & Dragon Ball Z Collaboration Special!! The Super Collaboration Special is a crossover between popular Shonen Jump anime Toriko, One Piece, and Dragon Ball Z, as the title implies. Although Toriko and One Piece have crossed over before, this is the first time Dragon Ball Z has been included. The first half of the episode, which aired instead of Toriko, featured the characters from all three series competing over a huge piece of meat. An energy-absorbing monster attacked the characters in the midst of their giant feast after the race in the second half, which took up One Piece’s time slot.

Overall, this Super Collaboration Special is simply a filler fan-service special episode that fits the usual storyline for such crossovers: the main characters from different shows fight in the first half before joining forces against a major enemy in the second half. And, as you’d expect from a crossover like this, the lead characters are all exactly similar in strength as they compete so that viewers of all three shows can keep their dignity—no matter how ridiculous the idea of post-Buu saga Super Saiyan Goku being on par with Luffy or Toriko is.

2. Cyborg 009 VS Devilman (2015)

Cyborg 009 VS Devilman (2015)

Evil organizations kidnap people and turn them into cybernetic weapons against their will in this world. It’s a world where demonic entities lurk in the shadows, waiting for the slightest sign of weakness to possess and consume human souls. It’s the world of Joe Kawagoe’s Cyborg 009 vs. Devilman, with Bee Media and Actas delivering the animation. Several decades in the making, Shotaro Ishinomori’s 1964 science fiction action epic Cyborg 009 and Go Nagai’s 1972 action/horror series Devilman are pitted against each other in a fight to the death in this three-episode OAV series.

When these dark heroes mistook each other for a new, unknown foe, they clashed. Cyborg 009 vs. Devilman is a strong effort in terms of superhero team-ups.  The story is more than just a pretext to pit the two factions against each other, but the animation, production design, and action choreography are all fantastic. Devilman vs. Cyborg 009 assumes that the audience is already familiar with both Devilman and Cyborg 009. The crossover takes place deep within both series’ continuity, following the ultimate confrontation with the Mythos cyborgs and Devilman’s battle with Jinmen.

3. Lupin III vs. Detective Conan: The Movie (2013)

Lupin III vs. Detective Conan The Movie (2013)

This movie is the second crossover between the Lupin III and the Detective Conan series is Lupin the 3rd vs. Detective Conan: The Movie. It occurs after the 2009 television special Lupin the 3rd vs. Detective Conan, and the plot incorporates elements from the previous series. The film opens with Kaito Kid committing yet another daring heist, this time with a magnificent diamond as his prize – except this time Kaito is merely a bystander. Other inconsistencies, in this case, include “Kid” making his getaway with a real gun and a high-powered boat rather than his standard hang glider cape.

Conan Edogawa pursues the assailant but is stopped by a shadowy figure who slices his skateboard in half with a sword; only then does he realize who the assailant is: Arsène Lupin III. Lupin, it turns out, is acting under duress; Fujiko Mine, his love interest, is in a hostage situation, with an explosive collar around her neck set to detonate if Lupin does not cooperate. The diamond theft, which Lupin discards shortly after, was merely a test of his abilities. His real target is a gemstone known as the Cherry Sapphire that his “employer,” a mystery man named Alan Smithee, is after.

4. Grendizer, Getter Robo G, Great Mazinger: Kessen! Daikaijuu (1976)

Grendizer, Getter Robo G, Great Mazinger Kessen! Daikaijuu (1976)

The Dragosaurus, a mysterious prehistoric animal living unnoticed in the oceans’ depths, causes panic by consuming massive amounts of oil all over the world until it begins to head for Tokyo. Despite this, Japan has some aces up its sleeve: Grendizer, Great Mazinger, and Getter Robo G, all of whom are dispatched right away to stop the monstrous creature. Unfortunately, the team is joined by the awkward Boss Borot, who ends up being swallowed by the Dragosaurus, making things even more difficult. Thanks to Great Mazinger, Boss Borot is able to escape the creature’s stomach.

While the three super robots battle Dragonsaurus, the beast travels to Tokyo and goes on a rampage. Getter Robo G uses the Shine Spark to ignite the large quantities of oil in Dragonaurus’ body, allowing the city to be saved. Grendizer, Getter Robo G, and Great Mazinger are the three super robot anime that make up the crossover film Grendizer, Getter Robo G, Great Mazinger: Kessen! Daikaijuu. The film, like the rest of Toei’s Vs. Animated films showcase alternate versions of events from each of the three series and is not canonical to any of them. Aside from the crossover, this film features typical mecha action.

5. Tsubasa: Reservoir Chronicle (2005)

Tsubasa Reservoir Chronicle (2005)

During an excavation at the enigmatic ruins of Clow Country, Syaoran learns that his childhood friend, Princess Sakura, appears on the site with wings dispersed into many feathers. When the feather disappears into various dimensions, so does the memory of Sakura. Syaoran goes to another dimension to find a cure in order to save Sakura’s life and recover her memories. There’s only one thing he can do at this point. To gather Sakura’s feathers, go across various dimensions.

Fay, a runaway magician who wishes to jump between worlds and never return to his own,  Kurogane, an exiled ninja from Japan Country who wishes to return to his world, and Mokona, a white meat-bun shaped creature, are all assisting with the quest. Coming from Clamp Studio, the developer of anime shows such ‘Magic Knight Rayearth,’ ‘Cardcaptor Sakura’ and ‘X/1999,’ ‘Tsubasa: Reservoir Chronicle’ is one of a kind of stand-alone series, featuring characters from all of the studio’s popular productions. The anime succeeds in taking some common elements from each universe to re-imagine a refreshing fantasy drama. Overall, this anime was well-received by both viewers and reviewers, who applauded the plot’s use of all well-known characters.

6. Isekai Quartet (2019)

Isekai Quartet (2019)

A magic button unexpectedly appears one day.  Protagonists from Re: Zero − Starting Life in Another World, KonoSuba, Overlord, and Saga from Tanya the Evil all press the button unintentionally, occasionally, and switch to a parallel world—another brand new isekai—where the unique tale of high school life starts. They will soon be joined by the characters of The Rising of the Shield Hero and Cautious Hero: The Hero is Overpowered but Overly Cautious. Isekai Quartet is an anime series that acts as a crossover in chibi-style. As a crossover, the Isekai Quartet stands out as a show of its own. The episodes contain half-length skit stories.

Its main goal is to amuse us with a substantial quantity of comedy in order to get our attention. The developers wanted to have as many segments as possible in the school setting. There are many chances for comedy, ranging from school rules to a class talent show.   Isekai Quartet takes a step back from the darkness and despair of RPG adventure and gives its heroes a taste of the real world, as well as a few other characters who understand their struggle.

7. Fairy Tail x Rave (2013)

Fairy Tail x Rave (2013)

While on a mission to locate and defeat a troublesome mage, a few Fairy Tail Guild members are separated in an unfamiliar place. At the same time, Haru, Elie, and the rest of their party are all separated. In a fortunate turn of events, Elie met Lucy and Happy, who are searching for Natsu. In the meantime, Haru stumbles across Natsu, who is suffering from motion sickness. While she appears friendly, Elie fits the troublemaker’s profile that Fairy Tail members have been assigned to find. To make matters worse, Natsu hears about Haru’s friendship with her and assumes that they are accomplices.

Fairy Tail x Rave is a crossover between two popular shows that follows the two groups as they explore their similarities. While the miscommunications add up, they’re matched against each other in an intense power struggle; however, they’ll have to work together to defeat a mutual foe. If you’re a fan of Hiro Hashima’s job, this one-episode crossover will carry you through an unforgettable journey down memory lane. Not only was this meeting an exciting encounter between Mashima’s prized works, but it was also the nostalgic return of an early Shounen hero.

8. Carnival Phantasm (2011)

Carnival Phantasm (2011)

Type-Moon is known for its thrilling Fate series and all of the ecchi content and dark drama that goes along with it. However, in honor of the company’s tenth anniversary, they decided to ditch the grueling death game that has caused so many of the characters to weep and doubt their own existence in favor of some light-hearted, funny scenarios. Carnival Phantasm has become the unusual joy of the modern age, allowing audiences to take a rest before the company’s next grim installment by bringing a range of characters from around the Type-Moon arsenal.

The anime is oddly addictive, despite being incredibly chaotic due to its large cast. When you see your favorite characters from ‘Tsukihime,’ ‘Fate/Stay,’ and ‘Melty Blood,’ you get a strange feeling of enjoyment, and the situations they go through are in no way related to their respective shows. It’s fascinating to see how this anime takes characters from three serious shows and gives them a whole new spin. Watch Lancer suffer from a low luck stat, or the self-centered King of Heroes readily kneel before a dominatrix King of Knights. Make sure that you leave your sanity at the door.

9. It’s a Rumic World: 50th Anniversary Weekly Shonen Sunday (2008)

It's a Rumic World 50th Anniversary Weekly Shonen Sunday (2008)

Rumiko Takahashi is well-known among Japanese anime and manga fans, especially those who enjoy the Shoujo series. Four of the most famous shows for early audiences include Urusei Yatsura, Ranma 1/2, and Inuyasha, everyone’s favorite demon dog romance. ‘Inuyasha’ is a classic anime that has captivated audiences for decades. Shounen Jump created a crossover of some of Rumiko Takahashi’s finest works in 2008 to pay tribute to the mangaka who created “Inuyasha.” The one-episode short ‘It’s A Rumic World: 50th Anniversary Weekly Shonen Sunday’ puts together characters from ‘Urusei Yatsura,’ ‘Ranma 1/2,’ and ‘Inuyasha.’

Despite its relatively brief length, the few moments the characters have are very funny and relevant enough to make this one a memorable crossover. The characters are acting just as you would expect them to, and in funny ways, almost like a crossover is normal to them. What makes this crossover really stand out from all the rest is the way the protagonists crack the fourth wall, where Inuyasha and Ranma realize that they sound the same, and even other characters like Kagome and Lum directly address the viewers.

10. Yu-Gi-Oh!: Bonds Beyond Time (2010)

Yu-Gi-Oh! Bonds Beyond Time (2010)

Yu-Gi-Oh! has shown time and time again that no dilemma can’t be overcome with a children’s card game. So it goes without saying that if the invention of the card game is threatened, the card game itself will be able to save it. The game’s life, as well as its entire past, is threatened by a mysterious character called Paradox. Yusei, Jaden, and Yugi form a time-traveling alliance to fend him off and protect the game that has shaped their lives and friendships. ‘Yu-Gi-Oh!: Bonds Beyond Time’ is the ultimate crossover film that brings together Yugi Mutou, Yusei Fudou, and Yuki Judai, the main characters of ‘Yu-Gi-Oh! GX’, and ‘Yu-Gi-Oh! 5Ds,’ respectively.

The three heroes are compelled to join forces to journey across time. If you’ve been a fan of the ‘Yu-Gi-Oh!’ franchise from the beginning, this one will bring back a lot of memories with the return of fan-favorite Yugi Mutou. Apart from that, this film features an intriguing time travel story that will keep you entertained during its length. Fans of ‘Yu-Gi-Oh!’ should definitely give this a watch.
