24 Adventure Time Fan Art Mashups You Totally Wish Were a Thing

Adventure Time may have wrapped up its original TV run, but the Land of Ooo is very much alive in fan art, mashups, and crossovers.
From comics and spin-offs like Fionna and Cake and new Adventure Time comics to endless posts on Tumblr, Reddit, and Pinterest,
artists keep reimagining Finn, Jake, and the gang in every pop culture universe you can think of.

One of the most fun trends is Adventure Time fan art mashups: art that blends the show’s squishy, noodle-limbed style with characters from movies,
games, anime, and more. Some of these mashups already exist in the wild as fan art, others are things we all secretly (or not so secretly) wish
someone would draw. Either way, they prove just how flexible and beloved the Adventure Time art style really is.

Why Adventure Time Fan Art Mashups Work So Well

Before we dive into 24 mashup ideas, it helps to understand why Adventure Time is such a perfect base layer for fan art crossovers.
The show’s designs are deceptively simple: round heads, dot eyes, bold outlines, and bright colors. Under that simplicity, however,
lies a surprisingly emotional, lore-heavy world that tackles everything from heartbreak to apocalypse-level magic.

That combosimple shapes plus deep feelingsmakes the style incredibly adaptable. Artists have already turned everything from
superhero teams to horror icons into Adventure Time-style characters, with lists on fandom and pop culture sites showcasing
crossovers that fans vote on and share like crazy.

Even within the franchise, “mashup energy” is canon: Fionna and Cake started as genderbent fan art and grew into actual episodes,
a full spin-off series, and now new comics. That’s about as strong an endorsement of fan creativity as you can get.

24 Adventure Time Fan Art Mashups You Totally Wish Were Canon

Below are 24 mashup ideas inspired by real fan art trends, crossover posts, and the broader mashup culture swirling around Adventure Time.
Some versions already exist scattered across the internet; others are just waiting for a brave artist with a sketchbook and way too many feelings.

1. Star Wars Time: Finn Skywalker & Jake Solo

Picture Finn in a slightly oversized Jedi robe, swinging a glowing green sword instead of his usual blade, while Jake stretches into a Millennium Falcon–shaped hover-pup.
Princess Bubblegum takes on a Leia-inspired braid crown, and Ice King becomes a tragic mashup of Emperor Palpatine and a very confused stormtrooper.
Star Wars x Adventure Time crossovers are already popular on fan boards and print shops, so this mashup fits right in.

2. Pokémon in the Land of Ooo

Now imagine Finn as a rookie trainer wandering across Ooo catching elemental creatures instead of fighting them.
Jake becomes a shape-shifting Eeveelution that can switch between all types at will, while BMO is basically a living Pokédex.
Candy Kingdom Pokémon (a marshmallow-type, anyone?) would be almost too adorable. Fan artists already love drawing Star Wars and other characters as Pokémon;
giving Ooo the same treatment is a natural next step.

3. Marvel’s Avengers of Ooo

“Avenger Time” has already been used as a parody name, and it’s easy to see why. Finn makes an excellent Captain America type,
Bubblegum turns into a lab-coat-wearing Tony Stark, and Marceline glides through the sky like a bat-winged Thor shredding on a lightning-charged axe.
Picture Jake as a chill, yellow Hulk who only hulks out when someone messes with Finn’s snacks.

4. Studio Ghibli x Adventure Time

Think of an Adventure Time–style Totoro lumbering across the Candy Kingdom, or Finn meeting a shapeshifted Jake-Dragon reminiscent of Haku.
The mashup practically writes itself: both universes are whimsical, emotional, and just a little weird.
Fan mashup boards already love Ghibli crossovers, and Ooo’s landscapes echo Ghibli’s lush, magical worlds.

5. Stranger Things in the Nightosphere

Now let’s drop the Hawkins kids into a place even stranger than the Upside Down: the Nightosphere.
Eleven and Marceline teaming up to fight surreal demons would be pure goth delight.
Finn and Jake stumble into a Demogorgon that looks suspiciously like one of Ricardio’s cousins, while BMO misinterprets psychic nosebleeds as a low battery warning.

6. The Legend of Zelda: Ocarina of Ooo

Finn has always had strong “Link, but chaotic neutral” energy, and fan art mashing the two franchises already exists online.
Imagine Finn in a green hat, with Jake stretching into a living hoverboard, and Bubblegum taking on the role of a candy-coated Zelda.
Dungeons in Ooo practically beg to be turned into Zelda temples anyway.

7. Harry Potter Meets Wizard City

Wizard City and Hogwarts are both full of unreliable magic and questionable safety standards, so this crossover feels painfully correct.
Finn and Jake show up as foreign exchange students, accidentally inventing new spells while Ice King tries and fails to get hired as a Defense Against the Dark Arts professor.

8. Sailor Moon Princesses of the Candy Kingdom

Bubblegum as Sailor Moon, complete with candy moon tiara; Flame Princess as Sailor Mars; and Marceline as an extremely over-it Sailor Saturn who plays transformation music on her bass.
The Adventure Time princess lineup practically begs for a magical girl-style group pose, and mashup fan art sites already show a soft spot for pastel, anime-inspired redesigns.

9. The Simpsons Vacation in Ooo

Homer tries to eat the royal tarts, Bart skateboard-pranks Peppermint Butler, and Lisa and Bubblegum have an unnervingly detailed conversation about quantum gum science.
The visual contrast between Matt Groening’s overbite-heavy designs and Adventure Time’s simple shapes makes this mashup irresistible for cartoon fans.

10. Gravity Falls x Adventure Time: Mystery in Ooo

Dipper and Mabel Pines tumble into a weirdness magnet even stronger than Gravity Falls and end up in Ooo.
Dipper obsessively documents every magical glitch in a battered journal while Mabel instantly becomes best friends with Lumpy Space Princess.
Fan communities already pair these two shows in memes and crossover threads, thanks to their similar “cute but existential” vibe.

11. My Hero Academia at Hero Camp

Imagine Finn attending hero training with Deku and Bakugo in a mashup of Ooo’s wilderness and U.A. High.
Jake’s stretchy abilities get classified as a top-tier quirk, while BMO becomes the world’s most chaotic support item.
The emotional stakes and over-the-top powers of both franchises mesh surprisingly well.

12. The Care Bears Visit the Candy Kingdom

The pastel chaos of Care-a-Lot meeting the pastel chaos of the Candy Kingdom is almost too much sweetness for one canvas.
Fan art communities already love reimagining classic ‘80s characters in modern styles, and seeing them in Adventure Time form would be a nostalgic sugar rush.

13. Rick and Morty Crash Into Ooo

Rick portal-guns straight into the Tree Fort mid-adventure and immediately tries to “fix” the magic of Ooo with science, obviously making it worse.
Morty panics, Finn thinks it’s awesome, and Jake just wants everyone to calm down and eat some everything burritos.
The tonal whiplash between Rick and Morty’s cynicism and Adventure Time’s earnestness would make for some wild fan comics.

14. Steven Universe Gems in Candy Armor

Steven and the Crystal Gems dropping by Ooo feels like a crossover about emotional healing.
Pearl geeks out over Bubblegum’s lab, Amethyst and Jake compete in a shapeshifting contest, and Garnet quietly vibes with Marceline over the whole “ancient, powerful, and very gay” thing.
Both shows lean into queer themes and emotional storytelling, so fan mashups already celebrate them together.

15. Mario Kart: Land of Ooo Grand Prix

Turn Tree Trunks’ orchard, the Ice Kingdom, and Fire Kingdom into racetracks, and let Finn, Jake, PB, and company tear around in ridiculous candy-powered karts.
Jake becomes the kart, obviously, stretching into whatever shape gives the best stats.
Fan mashup boards love “X characters in Mario Kart style,” and Ooo’s geography would make some chaotic tracks.

16. Spider-Verse, but It’s Finns from Every Dimension

The multiverse concept is already baked into Adventure Time, from Farmworld to variations seen in later comics and spin-offs.
Follow that up with a Spider-Verse–style mashup of dozens of Finn variantspunk Finn, vampire Finn, robot Finnall in the show’s signature style.
Add a glitchy BMO as the portal hub and you’ve got a fan artist’s dream composition.

17. The Nightmare Before Ooo

Jack Skellington wanders into the Nightosphere, mistakes Hunson Abadeer for a fellow holiday monarch, and chaos ensues.
An Adventure Time Halloween crossover lets artists combine lanky gothic shapes with the show’s rounded aesthetic for delightfully spooky mashups.

18. Adventure Time x Arcane: Runeterra of Ooo

Sprinkle some hextech into the Candy Kingdom and suddenly PB is reverse-engineering Zaun tech while Marceline plays gigs in Piltover’s underbelly.
Fans already love posting Arcane crossover art with other animated shows; giving it the Adventure Time treatment would highlight Arcane’s dramatic flair in a softer style.

19. Avatar: The Last Airbender in the Grasslands

Aang glides above the Grasslands, Jake waterbends his own stretchy body, and Finn trains as a sword-based non-bender watching in awe.
Both series mix philosophy, comedy, and heartbreak, so an Adventure Time–styled Team Avatar makes a ton of emotional sense.

20. Sailor Scouts of the Nightosphere

A darker twist on the earlier Sailor Moon mashup: Marceline leads a Nightosphere magical girl squad, complete with bat-winged transformation sequences and cursed transformation wands.
Fan artists love subverting cute aesthetics with horror elements, and Adventure Time gives them a ready-made sandbox.

21. The Office… but Everyone Works for Princess Bubblegum

The Banana Guards get a mockumentary treatment as stressed-out office workers; PB is the overqualified, perpetually tired manager;
and Lemongrab keeps filing HR complaints in all caps.
An Adventure Time x The Office mashup would be perfect for comic strips and reaction images.

22. Adventure Time x Minecraft: Blocky Ooo

We’ve already seen official Minecraft crossovers with other franchises, so an Adventure Time low-poly mashup feels inevitable.
Blocky Finn and Jake exploring voxel Candy Kingdom landscapes with pixelated Candy People? Yes, please.
Fan builders already recreate Ooo in sandbox games; stylized fan art is the next logical step.

23. Classic Disney Princesses Visit the Candy Kingdom

Cinderella, Tiana, and Mulan drop into Ooo and end up trading notes with PB, Flame Princess, and LSP about royal drama, moral dilemmas, and terrible suitors.
Fan art communities adore Disney crossovers, and seeing the princesses in Adventure Time’s round-eyed style would be pure fandom joy.

24. Adventure Time x Indie Comics: Title Card Mashups

One of the coolest parts of Adventure Time has always been its painted title cards, which already feel like miniature crossover posters.
Now imagine those title cards reinterpreted in the styles of indie comic artistsmoody, scratchy lines; risograph colors; zine aesthetics.
It’s less a single mashup and more a love letter to comics culture woven back into Ooo.

How Artists Actually Create These Mashups

Behind every “wow, I wish that were real” mashup is someone obsessing over character design details.
Artists who draw in Adventure Time style usually start by simplifying silhouettes: round heads, tube limbs, and minimal facial features.
From there, they add recognizable elements from the other franchiseiconic weapons, color palettes, hair shapes, or costumesuntil you can identify the crossover at a glance.

Many fan artists share process shots online: sketching in apps like Procreate, inking in bold digital lines, and finishing with flat colors and subtle texture brushes.
Others embrace traditional media, painting mashups on canvas, wood rounds, or even flower pots.
The result is a blend of classic cartoon energy with gallery-worthy creativity.

Communities on social platforms, fandom wikis, and humor sites help these pieces go viral.
People save, repost, and even vote on their favorite mashups, turning fan art into a kind of ongoing, crowdsourced collaboration built on top of the original series.

What It’s Like to Fall Down the Adventure Time Fan Art Mashup Rabbit Hole

If you’ve ever opened your phone “just to check a couple of Adventure Time mashups,” you already know how this story goes.
You start with one imagea Star Wars crossover, maybeand suddenly it’s an hour later, you’re 150 pins deep on a mashup board, and you’re genuinely considering learning how to draw.

The experience usually begins with recognition. You spot a character you love from another universeLuke Skywalker, Deku, or Sailor Moonbut something about them looks… softer, rounder, more exuberant.
Then you realize: they’re drawn in the Adventure Time style.
That “aha” moment hits a very specific part of your brain where nostalgia, internet culture, and cartoon reruns all live together.

As you scroll, you start to notice patterns. You’ll see how different artists solve the same design problems:
how do you translate Spider-Man’s mask into a two-dot-eye style?
What does a Demogorgon look like if it has to be at least 20% adorable?
Where do you hide Sailor Moon’s hair buns on a rounded Adventure Time head without breaking the silhouette?

At some point, the fan art stops being just “cool pictures” and starts feeling like a conversation.
Artists build on each other’s ideasone person’s Gravity Falls x Ooo mashup inspires another artist to try a darker, Nightosphere version.
A clever title card–style illustration sparks a whole thread of people reimagining other episodes with crossover title art.

If you’re a creator yourself, this can be both inspiring and dangerous (for your free time, anyway).
You might start sketching your favorite characters in stick-figure form, then slowly layering in more of that classic Adventure Time vibebig eyes, expressive mouths, wild backgrounds that look like they were painted during a sugar rush.
Even novices find the style surprisingly approachable; its simplicity invites experimentation rather than perfectionism.

Convention experiences crank that feeling up to eleven.
Walking artist alleys at cons, it’s common to spot entire print walls dedicated to Adventure Time mashupsrows of posters where each square is a different crossover:
superheroes of Ooo, anime squads reimagined as adventurers, horror icons rendered as strangely huggable.
The energy in those spaces is a reminder that fan art isn’t just a side hobby; it’s a living, buzzing part of modern pop culture that keeps shows like Adventure Time relevant long after their finales.

Even if you never pick up a pen or stylus yourself, getting pulled into this mashup universe changes how you see the original show.
After enough exposure to crossovers, you start watching Adventure Time episodes and thinking,
“Wow, this dungeon would make an amazing Zelda level,” or “This scene has big Spider-Verse montage energy.”
Fan art becomes a lens that refracts Ooo through every other fandom you loveand somehow, the show’s heart only shines brighter through it.

Wrapping It Up: The Mashup Magic of Ooo

Adventure Time fan art mashups exist because the show invites them.
Its world is flexible, its style is approachable, and its themes resonate with fans of everything from anime epics to vintage cartoons.
Whether it’s Star Wars lightsabers in the Candy Kingdom, Zelda temples in the Ice Kingdom, or multiverse Finns swinging through a Spider-Verse–inspired Ooo,
these crossovers are proof that the Land of Ooo isn’t a closed bookit’s a collaborative playground.

You might never see these 24 mashups turned into official episodes (although given how Fionna and Cake started, never say never),
but fan artists are already halfway there.
The next time you’re craving a creative hit of nostalgia and chaos, search for Adventure Time mashups and let yourself tumble into that delightful, weird, and wonderfully heartfelt rabbit hole.
