Superman might be faster than a speeding bullet, but even the Man of Steel needs a day off. Kryptonite, his most infamous Achilles’ heel, wasn’t part of the original lore. It was cooked up during a Superman radio show in 1943. Why? According to Screenrant, when Bud Collyer, the voice of Superman, went on vacation, the writers needed a quick excuse to sideline the hero. The solution? A glowing rock from Krypton that left him too weak to fight crime for a week.
The green menace didn’t jump straight into the comics, though. Kryptonite officially debuted in Superman #69 in 1949, but it wasn’t green back then. The deadly hue came years later when Superman was sabotaged aboard a ship lined with lead walls. The radioactive rocks were hidden so well that even his X-ray vision could not detect them.
But kryptonite isn’t Superman’s only head-scratching weakness. Fans have spent decades poking fun at his Clark Kent disguise. Seriously, just glasses? How does that fool anyone? Well, DC finally addressed the mystery in Superman #330. His glasses aren’t your average pair of specs—they’re made of Kryptonian Plexiglas from his spaceship. These super-specs use subliminal Kryptonian tech to project a different image of Clark.
Still skeptical? Fans have their own theories. Clark doesn’t just wear the glasses and call it a day. He leans into the persona—ill-fitting suits, a different hairstyle, and even a change in posture. Some suggest he compresses his spine to appear shorter than Clark. Talk about commitment to the bit!
Of course, kryptonite ain’t the only thing that keeps Superman grounded. While he’s practically unstoppable, he’s got a surprising list of vulnerabilities. His weakness in magic makes him an easy target for sorcerers and beings like Black Adam. Before James Gunn’s reboot plans, Henry Cavill’s Superman was on a collision course with Dwayne Johnson’s Black Adam, a showdown that would’ve capitalized on this magical Achilles’ heel.
And kryptonite? It comes in more flavors than an ice cream parlor. Green is the classic, but every color affects Superman differently. Prolonged exposure to the green stuff is deadly. Villains with a shard of kryptonite and a little creativity have always had a shot at leveling the playing field against the Last Son of Krypton.
But let’s get back to the throwback. Kryptonite’s journey from a radio show plot device to a cornerstone of Superman’s mythos is a testament to how even the most iconic stories are shaped by happy accidents. What started as a quick fix for a voice actor’s vacation evolved into the ultimate symbol of vulnerability for an invincible hero.
So, next time you see Superman struggling against kryptonite, remember: it all began with a week-long break and some clever storytelling. Even the strongest heroes need to take five—and sometimes, those breaks end up rewriting comic book history.
