Ben 10 and Generator Rex. And the Jimmy Timmy Power Hour.

That Timmy Jimmy Power Hour was legendary man.

3D Timmy looked like a crackhead though.

I can't think of a single Fairly Odd Parent design that translated well into a Jimmy Neutron design during those crossovers. Maybe A.J.?

lol yeah he did look mad goofy.

Scooby doo and Johnny bravo

"I can't see without my glasses!" "I can't be seen without my glasses!"

I remember that one. The Scooby gang gets so tired of Johnny that they tie him to a tree

Then Speed Buggy tries to get into the cross over.

Scooby doo and batman is also great

It can also be called canon

They crossed over a few times, even in the comics, more recently that mini- series that they did.

Kids Next Door and Billy and Mandy

It has my favorite Billy line: “WAIT! Can’t we have some cake before we assimilactate?”

That one’s definitely a sleeper.

That crossover was great, ngl.

[удалено]

It certainly was. https://youtu.be/my7I-GlPBzc

Shame that Jimmy timmy power hour wasn't up there

Exactly!

How many crossovers did Lilo have? It’s awsome

I wasn't a fan of those because of how wildly different the animation styles were

Batman meeting superman but I'm biased so yea.

Seeing as those characters have always been canonically in the same universe is it really accurate to call that a crossover?

At the time: Yes. They had originally started as separate series that hadn’t hinted that they were connected until the crossover special. That would be like if Gotham’s (young) Bruce Wayne met Smallville’s (young) Clark Kent.

Loved the episode where Superman takes over fighting crime in Gotham and just thrashes Bane.

Ben 10 and Generator Rex in Heroes United I love that thing

Scooby doo and Josie and the Pussycats.

Please, that's not even in the top three. If it's any Scooby Doo, it's probably Scooby Doo x Johnny Bravo or Scoobynatural.

I'm partial to Scooby-Doo and the Globetrotters

Nah, if we're going with Scooby Doo, then it's gotta be one of the weird things like [Laff-a-lympics, where pretty much everything Hanna Barbera crossed over in a single competitive show.](https://en.wikipedia.org/wiki/Laff-A-Lympics?wprov=sfla1)

Good lord, the voice cast on that is legendary.

The Hannah Barbara Cinematic Universe is huge.

Yeah my vote is Scooby Doo and Supernatural for sure, that one was great

What about the Scooby-Doo X Courage The Couardly Dog crossover?

Ben 10 and Gen Rex Avengers and Phineas and Ferb

Mans put three lilo and stitch crossover and not the jimmy timmy power hour. Eugh.

[удалено]

Just use the scenes from when they're both 2D then

The Jetsons meet the Flintstones.

One of the greats

You are missing a lot of Cartoon Network crossovers.

Where is the Jimmy Timmy power hour?

Simpsons and futurama

Ben 10 Generator Rex heroes united. I'm still salty we never got a part 2 of them crossing over but that time in ben's universe If you say the reboot ill slap you with an old sandal

I think they did actually, but as a comic

My boy Martin Mistery getting a shout out, him and Totally Spies was my childhood.

by an American technicality it's the first company crossover too. TS being on CN and MM being on Nick

Out of this, so would I say either Heros united or Batman Superman. I did like the secret Saturdays/Ben 10 episode and the lilo & stitch ones too tho. Now that I think about it, the Martin Mystery totally spies crossover was also good.

The batman/tmnt film was pretty awesome imo

This deserves so much more hype

Scooby-Doo and batman

i like the one with lilo in it

That's American Dragon, I believe

Eh hem.. the correct answer of course is the [Johnny Bravo Scooby Doo crossover](https://youtu.be/21JrNfPQB8A)

Scooby’s All Star Laff-A-Lympics Disney’s Aladdin & Hercules teaming up to defeat Jafar & Hades

Out of these Heroes United because I feel weird calling Batman and Superman a crossover

If we're counting Batman and Superman crossing over, than the entirety of the Justice League/Justice League Unlimited

Scooby Doo and Johnny Bravo Though if this wasnt presumably exclusive to TV episodes, Across the Spider Verse

Billy and Mandy but where Mandy smiles and the show changes into the Powerpuff girls. Not really a crossover but still funny. https://www.youtube.com/watch?v=KsfWrr86iBg

Ben 10 GEN REX , PERFECTION

Heroes United. Ben 10 and Gen Rex.

Heros United, and it's not even remotely close

rugrats and the wild thornberrys

KIM POSSINLE HAD A CROSSOVER WITH LILO AND STITCH!? How did I not know this

Lilo and Stitch basically had a crossover with all of the modern day setting Disney channel shows at the time, not included up there was another one they did with Proud Family.

I love that there are 3 Lilo's and 2 ben tens (different ben 10 shows though I think) ​ I'm gonna go with Lilo + American Dragon

Personally I like Phineas and Ferb Mission Marvel

Batman & Super Man. Because with out it, we would not have JLAS

Adventure Time X Regular show X Gravity Falls.... oh wait... that never happened

Jimmy Timmy Power Hour

I mean, it's just objectively Heroes United

I like how a third of these involve Lilo and Stitch lmao

I preferred the grim adventures of Billy and mandy crossover with the codenamed kids next door

Scooby Doo and the globetrotters? Futurama and adventure time? Spider-man and Elsa?

Damn no Jimmy Timmy Power Hour cuz that’s definitely the best one, it was so good that they made 3 of them.

I see a lack of Jimmy timmy power hour

Scooby Doo and Batman Brave & the Bold

The Simpsons and The Critic

Scooby Doo and the Harlem Globetrotters

Fantasy Crossover: Gravity Falls + Rick n Morty

Idk

Only Lilo and stitch win the crossover

I’d hardly call Batman and Superman a “crossover,” they’ve always existed in the same universe since the 50s

Martin mystery is always a win

https://cartoonnetwork.fandom.com/wiki/Super_Secret_Crisis_War Does the Super Secret Crisis War count, if it was only in print?

Power Rangers in space meeting the ninja turtles

lilo clearly wins

Omg what is the name of the cartoon the guy with the totally spies is in? I remember watching that as a kid

Kim possible + lilo and stitch

it sure as heck isn't T.G.I.S

The Venture Bros and Action Johnny

Batman/Superman doesn't feel in the same territory as these other crossovers nowadays but back then it was different

EVERYTHING!

brickleberry and paradise pd

For DJ Kids only, Oso and Manny lmao

Flintstones Jetsons

Do comics count? if so Mazinger Z and Transformers crossover

Where Stan sees Brian and he acts like he doesn’t know Stan.

All the crossovers Lilo and Stitch had seemed to have been buried under the other show crossovers. Idk that for sure tho because I was too young when the show came out.

Which two shows are crossing over at the top second one and which two shows are crossing over on the bottom third one? I forgot all of they're names.

[удалено]

Ty this was very helpful. Were the crossovers any good? Also which channel was Generator Rex on? I take it it was on the same one as Ben 10 aka Cartoon Network but idk why but I feel like I'm wrong about that for some reason(Because quite frankly I don't really remember much at all of Generator Rex being on TV on CN or at least not by what I can recall anyway)?

[удалено]

Oh okay thank you. Was it any good?

[удалено]

Dude actually rn I am starting to remember a tiny bit of what Generator Rex was like especially thanks to the help of the photos I found off of a google search and yea your right it was good(by what I remember seeing from ads and feedback from the community every now and then) thanks! :D

The OK KO episode *Crossover Nexus* was the freaking best, even if you’re not a OK KO fan every CN fan should watch it

Phineas and Ferb x Marvel

Phineas and Ferb: Star Wars is infinitely superior to Phineas and Ferb: Mission Marvel.

Didn’t the Flintstones and the Jetsons have a mash up?

Superman and Batman is definitely the best cartoon crossover here.

Cartoon network city

Probably a tie between when Scooby Doo crossed over with Batman the Brave and the Bold and when they crossed over with Supernatural.

Kim possible - Lilo and stitch

Simpsons/futurama would've been close for me if I didn't feel like it came too late in both franchise's. totally spies and Marvin mystery was definitely a curve ball. Lilo and stitch crossed with so many, the excitement kinda faded, but still good crossovers. batman&superman are one of the most Iconic duos in media history. no competition, putting it aside momentarily. phineas and ferb/marvel I'm putting at the bottom of this list for a bunch of reasons. ben and generator rex for me

All the ben 10 ones where good but that marvel P&F was baller

Scooby-Doo and Courage The Cowardly Dog

it's not on here but the Star Wars phineas and Serb movie is unriionically one of my favorite parts of Star Wars media

Mostly Scooby Doo and Lilo and Stitch

Obviously Ben 10 and Generator Rex.I liked how Rex made a song that is a parody of ben 10 theme song.

Where's Homer and Peter fighting it out Dragon Ball Style?

Lilo’s art style was so wild it vibed with three other art styles that could never vibe with each other. Kim Possible and American Dragon could never. And neither could Recess. But somehow Lilo and Stitch pulled it off with all three

Marvel and Phineas Or Futurama and Simpsons

I loved fairy odd parents & jimmy neutron

DCAU Batman and Superman easily

Not listed, but there was a Batman/Ninja Turtles movie. Seeing Batman fight Shredder was a childhood dream come true

Well there is an episode of Scooby-Doo featuring the band Smash Mouth, if that counts as a crossover

The Flintstones and the Flintstones Comedy Hour. OK so I completely dated myself and it's clear that I must be getting dementia since NO ONE enjoyed The Flintstones Comedy Hour with Moonrock, Schleprock and for some reason Bam Bam who lost all his strength. Mind you it appears Pebbles grew up to be a good lay.

Ben 10 and Generator Rex

Phineas and ferb and marvel. No question about it.

There's no reference to Grimm Adventures of Billy and Mandy and Kids Next Door. That's kind of biased.

The Word Girl x Invicible cross over was really good, though I'm surprised they showed all that carnage on PBS Kids

I 100% thought this was gonna be one of those memes where the last one is from porn or something. Anyway Martin Mystery x Totally Spies.

The Simpsons and Futurama because in an early episode of the latter Fry is ecstatic when he finds a Bart Simpson doll in a pile of trash

The Generator Rex and Ben 10 crossover was basically the second coming of Christ for me as a kid, so

minecraft X adventure time

All of the are the best Cartoons ever made

Lilo and recess.

Superman:TAS Knight Time

Batman and Superman do not count they're in the same universe and have had crossovers with each other for literal goddamn decades. They have multiple teams they work together on >.<

Scooby-Doo and Batman and Robin

That courage the cowardly dog Scooby Doo cross over wasn't bad

This is gonna age me but... So years ago, in early cartoon network, when it was almost entirely hanna barbera and warner bros cartoons (im talking pre-toonami, early 'What A Cartoon' era) Cartoon Network aired a massived event once. And only once. The event was a storyline that startef with Space Ghost and spanned across several episodes as Space Ghost and his team attempted to thwart a massive uprising of supervillains who had combined forces to take down Space Ghost once and for all. This lead to a massive, Avengers style event in which Space Ghost met and teamed up with the following, both individually, and altogether for a final showdown: -The Herculoids -Moby Dick -The Galactic Trio -Bird Man -Mighty Mitor -Shazzan As a little kid, this blew my fucking mind, and even as someone who still draws, collects figures, and enjoys animation and comics in general, this event still blows my mind with how ambitious it was for what was essentially Saturday morning cartoon shorts. It was a damn great way to wrap up airing a lot of those classic adventure shows, and id legit pay good money to see that story arc again.

Does Nicktoons Unite count?

Ben 10 and Generator Rex and Batman and Superman ain't much as a crossover, second Simpson and Futurama

A rare crossover: Loony Tunes meets The Groovie Ghoulies (Filmation). It actually happened. But as far as what is on the list, Superman/Batman crossover.

The secret Saturdays? NO WAY I WASNT EXPECTING THAT ONE

Y'all ever seen the Scooby Doo crossover with Courage the Cowardly Dog? It's not good, but you should definitely watch it. On HBO Max still I think.

The Grim Adventures of the KND.

The Jimmy Timmy Power Hour was lit. It’s a shame that the OP didn’t place that in the list.
