Curious about Majin Sonic from Sonic CD? Here’s the real story—how a silly developer joke became creepy legend, its big comeback in Friday Night Funkin’ mods like “Endless,” and why fans can’t stop talking about it even now in 2026. Fun is infinite, after all!
You’re a kid in the ’90s, popping in your Sonic CD disc, flipping through the sound test menu just for kicks. Suddenly this freaky, grinning Sonic face fills the screen—black eyes, purple shade, huge smile, and text saying “Fun is infinite” with some Japanese scribbles. Heart skips a beat, right? That’s Majin Sonic for so many of us. It looked spooky, but turns out it’s way more wholesome than it seems.
This little hidden thing has been messing with people’s heads since 1993, and then Friday Night Funkin’ blew it up all over again. Let’s walk through the whole thing like we’re chatting over snacks—no fluff, just the good stuff.
Key Takeaways
- Majin Sonic started as a fun little self-portrait Easter egg in Sonic the Hedgehog CD, drawn by developer Masato Nishimura using his old nickname.
- The creepy feeling mostly comes from the weird pixel grin and that haunting U.S. music track—nothing evil or cursed about it.
- It got huge love in the Vs. Sonic.EXE mod for Friday Night Funkin’ thanks to the song “Endless,” where he’s this polite, endless-fun guy who just wants to rap forever.
- Fans are still making new stuff with him in 2025 and 2026—mods, animations, chaotic battles—keeping the mix of spooky and silly alive.
- All those old rumors (demon signature, anti-piracy trap, mustache debate) got cleared up ages ago.
Where Majin Sonic Came From
Think back to the early ’90s. Sega was wrapping up Sonic the Hedgehog CD, and one of the landscape guys, Masato Nishimura, wanted to sneak in something personal. His nickname back then was “Majin”—just a fun twist on his name Masato, nothing dark or demonic. (In Japanese it can mean “true person” in this context, not devil stuff.)
So he coded in this secret screen. Go to the title screen, hit Down three times, Left, Right, A to pop open the Sound Test menu. Punch in FM 46, PCM 12, DA 25—and there it is. A bunch of wagging-finger Sonic clones line the back, and up front you get this purple-tinted, earless Sonic face with a giant grin, empty black eyes, and text like “Fun is infinite. —Sega Enterprises— Majin.”
It was basically Nishimura saying “hey, thanks for playing, have fun forever” in his own goofy style. No spooky intent, just a developer leaving his mark like graffiti on a wall.
How to See Majin Sonic Right Now
If you want to check it out yourself (and you should—it’s quick), grab a modern version of Sonic CD. Steam, Nintendo Switch, or even the collections on other platforms work great.
Here’s the easy steps:
- Fire up the game and reach the title screen.
- Press Down, Down, Down, Left, Right, A to unlock the Sound Test.
- Dial in FM to 46, PCM to 12, DA to 25.
- Sit back and watch/listen.
The Japanese version’s music is bouncy and silly, but the U.S. one has this low, eerie tone that really amps up the weird factor. That’s probably why so many folks thought it was haunted. If you’re using an emulator like RetroArch on your PC or phone, crank up the pixel scaling so the details pop even more.
Busting the Biggest Myths
Word spread fast back then, and the internet made it worse. People said wild things about this screen. Let’s knock them down one by one.
- Demon signature? Nope. “Majin” here is just Nishimura’s nickname—playful wordplay on his name. He said so himself in interviews.
- Anti-piracy thing? Some thought it only showed on bootleg copies to freak people out. Wrong—it triggers on legit discs if you enter the code right.
- Mustache debate? Fans argued for years about shadows under the cheeks looking like a mustache. Nishimura laughed it off: pure shading, no facial hair.
The image does look unsettling—human grin, void eyes, purple haze. But that’s pixel art limits plus soundtrack choices. No curses, no Satan, just a guy having fun at work.
How Friday Night Funkin’ Made Majin Huge
Jump to 2021. Friday Night Funkin’ was everywhere, and modders started pulling in weird Sonic characters for rap battles. The Vs. Sonic.EXE mod dropped Majin Sonic into the spotlight with “Endless” (that hidden Act ∞ stage).
You mess with a fake Sound Test menu, and suddenly you’re facing him. He’s all smiles, super polite, going “The fun never ends!” Clones pop up in a purple forest, and the beat just keeps going. Lose the battle and stall? The clones inch closer—not gory, just “come on, keep rapping!”
That song blew up—millions of views on remixes, playthroughs, you name it. Suddenly Majin wasn’t just a creepy old Easter egg; he was this theatrical, fun-obsessed character who lives for endless jams.
Majin vs. Sonic.EXE—Quick Breakdown
People mix these two up all the time, but they’re totally different beasts.
- Personality: Majin wants joy, rap battles, and non-stop fun. Sonic.EXE is a straight-up soul-stealing monster.
- Backstory: Majin is real Sega history. Sonic.EXE came from creepypasta stories online.
- In mods: Majin runs friendly (endless) sessions in “Endless.” EXE is the big bad terror boss.
- Fan vibe: Majin gets cute, goofy drawings and memes. EXE stays nightmare territory.
Majin’s “scary” side feels more like weird cosmic playfulness than actual horror.
What’s Happening with Majin Sonic in 2025–2026
Fast-forward to now, and he’s still going strong. Fans drop new Steam Workshop fighters where Majin zips around with clone tricks and rubber-hose chaos. YouTube’s full of fresh boss animations—imagining him duking it out in Sonic CD zones. People remake “Endless” tracks with extra madness or mash him up with other characters.
Some portray him as this eldritch fun machine; others lean wholesome and silly. That split keeps him interesting—no single take wins out.
