A new fan-made Super Smash Bros browser game is getting huge attention online because it lets players battle as more than 1,000 unusual fighters. Called Smash.fun, the project includes characters based on Lionel Messi, Albert Einstein, Santa Claus, Taylor Swift, John Cena, and many more famous faces.
The biggest surprise is that players can also create their own fighter by uploading a photo. The game turns that image into a low-poly character that can be used inside a version of the original Nintendo 64 Super Smash Bros game. Smash.fun was created by developer Thomas Dimson and is not an official Nintendo release.
Smash.fun is a fan-made browser project based on the original Super Smash Bros for Nintendo 64. Instead of downloading a separate game, players can open the website in a browser and use custom fighters inside the classic Smash 64 experience.
The project has become popular because it does something most Super Smash Bros games do not do: it gives players access to a massive list of funny, unexpected, and user-made fighters.
You can find characters based on celebrities, athletes, historical figures, internet personalities, and fictional characters. Some of the reported fighters include:
Lionel Messi
Albert Einstein
Santa Claus
Taylor Swift
John Cena
Donald Trump
Steve Jobs
Snoop Dogg
Elon Musk
MrBeast
Dwayne “The Rock” Johnson
Hideo Kojima
The roster has more than 1,000 fighters, which makes it very different from official Smash games. Official Super Smash Bros games have carefully designed Nintendo and guest characters, while Smash.fun focuses on strange, funny, and community-made matchups.
Who Made the Super Smash Bros Browser Game?
Smash.fun was created by Thomas Dimson, a developer who shared the project online in early September 2026.
Dimson explained that he loved Super Smash Bros 64 but wanted to be in the game himself. That idea led him to modify the original game so it could run in a web browser and include him along with more than 1,000 other fighters.
The project quickly spread on social media because of the wild character combinations it allows. Players can imagine matches that would never happen in an official Nintendo game, such as:
Lionel Messi vs Santa Claus
Albert Einstein vs Taylor Swift
John Cena vs MrBeast
A player’s own custom character vs a famous celebrity
Yes, Smash.fun lets players make a custom fighter using their own photo.
Players can upload an image, choose a name, and let the tool create a character for the game. The final fighter is designed in a low-poly style that matches the look of Nintendo 64-era games.
However, it is important to understand how this feature works. Uploading a photo does not create a completely new character with original attacks, voice lines, animations, and special moves.
Instead, the custom character uses one of the original Super Smash Bros 64 fighter foundations. The project creates a new-looking model, portrait, stock icon, and other menu assets, but the fighter is still built around an existing character setup.
That means your custom fighter may look like you, your friend, a pet, or a favorite celebrity, but its movement and battle style are based on the original Smash 64 fighters.
For example, a custom fighter made from your selfie may have a new face and model, but it could use the general fighting style of Mario, Link, Fox, Kirby, or another original character.
How Does Smash.fun Create Custom Fighters?
The custom fighter system is one of the most interesting parts of the project.
The game takes a player’s uploaded image and uses it to make a low-poly 3D fighter. Low-poly means the character uses simple shapes and fewer details, similar to many games from the Nintendo 64 and early 3D gaming era.
The tool can create several things for each custom fighter:
A playable low-poly character model
A portrait for the character select screen
A stock icon for matches
A series or character symbol
A custom announcer-style name call
A fighter that works with an original Smash 64 character rig
This helps each custom fighter feel more complete than a normal image edit or character skin. Instead of only seeing a picture on the screen, players can use the character in actual Smash-style battles.
It is a fan-made project inspired by the original Super Smash Bros for Nintendo 64. Nintendo did not create, publish, approve, or officially support the website.
This is important because some people may see gameplay clips online and assume Nintendo released a new browser version of Super Smash Bros. That is not the case.
Smash.fun is a community project that uses the classic Smash 64 format as the base for its custom fighter idea. The official Super Smash Bros series is still owned by Nintendo.
The website describes itself as a fan-made browser port, and Thomas Dimson has said that he modified the original game to run through a browser.
Do You Need a Super Smash Bros ROM?
Smash.fun does not include a free copy of Super Smash Bros 64 for players to download.
Players need to provide their own legally obtained copy of the original Super Smash Bros ROM to use the project. The game files are meant to stay on the user’s device instead of being hosted by Smash.fun.
This is an important point for anyone interested in trying the project. The site is not a replacement for buying or owning the original game, and it does not claim to be an official Nintendo service.
Players should be careful about where they get game files. Downloading copyrighted ROMs from random websites can create legal and security problems. The safest choice is to use a legally dumped copy from a game you personally own.
Why Are Fans Talking About Smash.fun?
The idea is simple, but it is also very funny.
Super Smash Bros has always been about dream battles between popular characters. Nintendo’s official games let Mario fight Sonic, Link, Pac-Man, Mega Man, Sephiroth, and many other gaming icons.
Smash.fun takes that idea in a completely different direction.
Instead of only using game characters, it lets people imagine celebrity, historical, and internet culture battles. A player can watch Santa fight Lionel Messi, make Albert Einstein face off against John Cena, or create a fighter based on themselves.
That level of customization is why the project feels fresh. It turns a classic Nintendo 64 fighting game into a strange online character playground.
It is also a good example of how fan creators continue to find new ways to revisit older games. Smash 64 was released decades ago, but browser technology, custom models, and modern image tools have given fans new ways to experiment with it.
Is Smash.fun Safe to Try?
Like any fan-made project, players should be careful before uploading personal images or using unofficial websites.
If you plan to try Smash.fun, keep these points in mind:
Only upload images you are comfortable sharing.
Do not upload private photos of other people without permission.
Do not use copyrighted game files from unsafe download websites.
Remember that the project is not made or supported by Nintendo.
Check the website’s current privacy information before uploading a selfie.
Avoid sharing personal details through your custom fighter name or image.
The custom fighter feature is fun, but players should still think before uploading personal photos online.
Will Nintendo Take Down Smash.fun?
There is no confirmed answer yet.
Nintendo is known for protecting its games, characters, music, and intellectual property. Because Smash.fun is a fan-made project connected to Super Smash Bros 64, there is always a chance that Nintendo could take action in the future.
For now, the project is getting attention because it does not appear to host Nintendo’s original game files itself. Players are expected to use their own legally obtained ROM, while the browser tool focuses on custom fighters and gameplay features.
Still, that does not guarantee the site will remain online forever. Fan projects can change, disappear, or receive legal notices at any time.
Smash.fun Makes Smash 64 Feel New Again
Smash.fun is one of the most unusual Super Smash Bros fan projects in recent memory. It takes the classic Nintendo 64 game and adds a modern twist with browser play, more than 1,000 fighters, celebrity characters, and a photo-based custom fighter tool.
The project is not official, and players should understand the legal and privacy limits before trying it. But as a creative fan experiment, it shows why Super Smash Bros remains so popular after all these years.
Whether you want to see Lionel Messi fight Santa Claus, Albert Einstein battle John Cena, or turn your own selfie into a Smash fighter, Smash.fun offers a strange and memorable version of the classic Nintendo 64 brawler.
