"All Your Base Are Belong to Us" comes from a hilariously mangled English translation of the opening cutscene in Zero Wing's Sega Mega Drive port. In the scene, the villain CATS appears on the bridge of a starship to announce that he's taken over all the player's bases. The original Japanese line, "君達の基地は、全てCATSがいただいた," roughly translates to "All of your bases have been taken over by CATS"8. What players got instead was a string of grammatical disasters: "Somebody set up us the bomb," "You have no chance to survive make your time," and the crown jewel, "All your base are belong to us"2.

The entire script reads like someone fed Japanese through a blender and reassembled whatever came out. According to Toaplan programmer Tatsuya Uemura, the translation was handled by a design team member in charge of overseas business, not a professional translator. Uemura admitted the team member's English skills were "really terrible"5.

"All Your Base" was arguably the first internet meme to cross over into mainstream media coverage. In March 2001, USA Today described it as "a kind of Web fungus" that "grabbed the attention of thousands"15. Wired called it proof that "armies of marketers toiling for years can't figure out how to grab Web-users' attention, and then a flash file with screen-shots from an outdated arcade game accompanied by clumsy subtitles conquers the world"3.

The Guardian's Rich Johnston noted the missed commercial opportunity: "If Sega had attached its name to the original animation, new life may have been breathed into its now cancelled Sega Dreamcast console. If Nike had placed their swoosh upon it, they'd have cleaned up"1. This observation about brand-adjacent virality was remarkably prescient for 2001.

The meme's reach extended into government and politics. The 2003 Sturgis, Michigan sign incident resulted in police involvement5. The 2004 TV ticker hack in Raleigh forced News 14 Carolina to overhaul their weather closure reporting system9. Alexandria Ocasio-Cortez's 2019 tweet using the phrase showed the meme still carried cultural currency nearly two decades after its peak5.

Multiple video games paid tribute. World of Warcraft included a "For Great Justice" ability10, and Guild Wars featured it as a warrior shout skill12. The Legend of Zelda: Breath of the Wild hid "all your base are" in its fictional script language during the E3 2016 demo5.

The gap between Zero Wing's 1991 release and the meme's explosion a decade later makes "All Your Base" one of the earliest examples of a dormant cultural artifact being resurrected by internet communities. For nearly seven years, the bad translation sat unnoticed in a European-only Mega Drive game that most North American players never saw7.

The meme's archaeology runs through a specific chain of gaming sites. After the animated GIF appeared on Zany Video Game Quotes, it circulated among a tight-knit group of gamers and tech workers. The site owner at Zany Video Game Quotes would later post an impassioned plea on the front page: "For the love of god, STOP! You're killing it! The poor Zero Wing intro never even saw it coming"3. This was one of the earliest recorded instances of a meme's originator begging the internet to let a joke die.

The Something Awful Photoshop thread in November 2000 was the critical mass event. Users competed to outdo each other with increasingly elaborate edits. Uncle Sam pointing at the screen, Bart Simpson writing the phrase on a blackboard, the cover of Time magazine with President Bush, airplanes branded with the slogan, road painters daubing it onto streets1. The thread hit sites like HardOCP and Planet Namek, which temporarily added AYBABTU references to their page titles14. It was, as Wired put it, "the Dada reality of a medium that refuses to be tamed into predictability"3.

Joshua Schachter, editor of the memepool message board, offered one of the best contemporary explanations for why it worked: "The incongruity of 'engrish' in a reasonably nicely produced game is funny, much like professionally printed signs that happen to contain typos. It works well as a catchphrase and slogan and fits easily into many different contexts. And, as any 12-year-old or online gamer knows, anything that was funny once is funnier when you repeat it 100 times"3.

The meme didn't just stay online. In April 2003, seven people in Sturgis, Michigan placed signs around town reading "All your base are belong to us. You have no chance to survive make your time." Police chief Eugene Alli called the signs "a borderline terrorist threat" since the US was at war with Iraq at the time5. In February 2004, North Carolina State University students exploited a web-based weather closure reporting system to inject the phrase into a live News 14 Carolina broadcast ticker, alongside messages like "h4x0r3d Computer Services Inc." and "1337 5p34k Linguistic Services"9.

YouTube got in on the joke on June 1, 2006, replacing the entire site with "ALL YOUR VIDEO ARE BELONG TO US" during maintenance. When users panicked that the site had been hacked, YouTube added: "No, we haven't be [sic] hacked. Get a sense of humor"13. A YouTube spokesperson told CNET, "This is what the engineers do, they have fun with our users. You have to remember who our fan base is. They don't want some dry message"13.

The phrase kept popping up in unexpected places. On June 12, 2014, Elon Musk titled a Tesla Motors blog post about opening their patents "All Our Patent Are Belong to You"4. On January 19, 2019, congresswoman Alexandria Ocasio-Cortez tweeted "All your base (are) belong to us" in response to a poll showing Republican support for her proposed 70% marginal tax rate5. Video games including World of Warcraft and Guild Wars built direct references into their gameplay412.

In February 2023, Bitwave Games re-released Zero Wing on Steam, but initially included only the 1989 arcade version, which lacked the famous intro11. The Steam page referenced the memes prominently, drawing criticism for selling nostalgia without delivering the actual source material. After backlash, Bitwave confirmed they'd patch in a reimagined version of the CATS intro scene11. On March 2, 2023, they uploaded the reworked cutscene to YouTube, featuring a slightly redesigned CATS and the classic dialogue4.

The speed of the meme's 2001 lifecycle was itself a story. The Guardian noted that "a few years ago, a craze could last for years before being picked up by the mainstream, giving it at least six months of credibility. Now it takes two weeks"1. Within days of mainstream attention, message boards were already deriding newcomers who posted new edits. The article called it "dead" in February 2001, just weeks after the explosion. But the phrase proved more durable than anyone predicted, embedding itself in internet culture for over two decades.
