Top 10 Craziest Anime Crossovers Ever

Welcome to WatchMojo, and today we are counting down our picks for the Top 10 Craziest Anime Crossovers.

For this list, we’ll be looking at times multiple anime series joined together in the wildest ways possible, resulting in some unconventional interactions our inner fanfic writers could only dream of. Were these mix-ups worthy of legend or just a set of cheap cameos? Let us know in the comments!

It’s a cluster of gags involving a bunch of classic anime icons that barely reaches over the three minute mark. Basically, a barrel of a fun for old school fans. You’ve got the unexpected trifecta of Inuyasha, Ranma ½ and Urusei Yatsure all colliding, and considering how many of those contain hotheads with a knack for battle, it isn’t long before everyone starts throwing hands. That, and we get to see Lum, Kagome and female Ramna again, each with beautifully updated visuals, so there’s a bonus!

Now here’s a crossover in the making, one that stretches back decades. Might sound a bit out there to have Go Nagai’s demonic anti-hero butting heads with a group of rather…aesthetically challenged machines, but the result is actually lit in the most unexpected of ways. From a visual standpoint it's rather outstanding, lending itself to some impressive fight scenes where we see Hell battle it out with the power of science. Ironically, it’s also Devilman’s least soul-shattering on-screen venture since his Cutie Honey cameo. About time Akira got off lightly!

“Dragon Ball Super” (2015-18)

It’s not the first time that Goku has interacted with an adorable robot that somehow surpasses the strengths of all Saiyan’s, but this most recent collab was far away the funniest. Not only does Arale prove herself to be the strongest being in existence, but does so at the explicit expense of Vegeta. Poor guy gets his ass handed to him by a mechanical elementary schooler. Throw in some great gags courtesy of Beerus, and while this filler episode may be wholly jarring, by itself it’s a solid laugh!

The Fate franchise is many things – convoluted, confusing, gorgeously animated and more depressing than a graveyard. Not the kind of place you’d expect to see off the wall comedy, which is what makes this spin-off feel so out of the blue. Essentially, any and all masters and servants from across the Fate-verse along with characters from Tsukihime and other Type Moon franchises are thrown into an endless slew of parodies and slapstick. We definitely don’t recommend you start with this one, but if you want to see the cast actually smile for once, it’s worth checking out.

This shouldn’t have worked. There was no way putting several fundamentally different anime into a high school setting with a chibi art style was going to work, especially if the only thing to connect them was the fact they all stemmed from the isekai genre. We were so wrong. The interactions between the casts of Re;Zero, Shield Hero, Overlord, Tanya the Evil, and KonoSuba are hilariously on point, keeping true to the characters without all that doom and gloom their shows are known for. If anything we want to see them keep packing in new additions! Cautious Hero where you at?

What happens when the world’s greatest detective takes on the world’s most uncatchable thief? A delightful crime caper that pits Conan’s one truth against Lupin and his devilish luck. While far mellower than what Lupin fans might expect from something starring Fujiko, watching these two unorthodox intellects try to trip one another up makes for a great time. Their eventual team up may have been predictable, but they proved to be such an unstoppable force together that they could probably bring down the Black Organization within a day.

“Gintama” (2006-13)

Gin and the rest have parodied so many other anime that it’s sometimes a shocker they didn’t get sued to hell and back. Among their many dalliances with the fourth wall, slice of life comedy Sket Dance came under fire multiple times, in the most endearing Gintama way of course. This eventually led to a legitimate crossover that saw Odd Jobs Gin actually clash with the Helper’s Club over such issues as having a parallel premise, occupying their old time slot, and other craziness, to the point where the whole thing becomes a whirlwind of WTF!

A failed student, a guy on a motorcycle and a kid with ancient Egyptian personality disorder all walk into a card to prevent the destruction of time. That’s not a terrible joke, that’s the premise of what might be the most outlandish Yu-Gi-Oh movie to date. Taking on a time-travelling madman whose world was somehow devastated because of card games, the protagonists of Yu-Gi-Oh, GX and 5Ds team up for a three vs one duel that is sure to get any duellist pumping. Sure, the premise is insane, but it’s a treat for fans!

Oh yeah, Rave Master was a thing back in the day. At least until Hiro Mashima found overwhelming success with Natsu and the mages over at Fairy Tail, wherein Haru and his Ten Commandment Sword were left behind. Thankfully, both of Mashima’s works were brought to the forefront together in a surprising, fun reunion of sorts that had both casts cross blades before teaming up to cause some mayhem on some unlucky bad guys.

“One Piece” (1999-)

Now this is how you do a crossover! What’s the plot here? Who cares? It’s a tournament arc featuring Luffy, Goku and Toriko beating the hell out of each other with all the bells and whistles. It’s so in your face and surface level, yet the hype could not be more real. Say what you will about why a Super Saiyan would struggle against a super chef and a rubber man, it’s still awesome to see them battle it out. Our one complaint? We needed way more focus on the fight between Zoro, Vegeta and Zebra. Let’s be honest guys, they’re the most interesting characters out of the bunch!
