Spider-Man is quite possibly the most iconic and beloved superhero out there. From his early days in Amazing Fantasy #15 to his household-name status across generations, Spidey has swung into the hearts of millions. But even if you feel like you know it all about Peter Parker, there are a few things that may surprise you. Let’s dive into 10 surprising Spider-Man facts you probably didn’t know—each one shedding light on the many layers of his story.
Spider-Man Is Hyphenated for a Reason
You’ve read the name a million times as “Spider-Man,” but ever wonder why it’s hyphenated? This wasn’t a stylistic whim—it was a deliberate choice on the part of Stan Lee. When Lee originally wrote the name down on paper, he was struck by how much “Spider-Man” resembled “Superman.” To make it not sound like an unintended hybrid, he threw in a hyphen to make it visually clear. Now, that little dash is iconic. Seriously, give it a try without the hyphen—it just doesn’t read the same.
He Was Almost Called “Flyman”
Prior to Spider-Man, Stan Lee brainstormed other bug-inspired names. After the Fantastic Four success, Lee was trying to think of his next major hero when he noticed a fly walking up the wall of his office. That small moment of inspiration gave birth to ideas such as Mosquito Man, Insect Man, and Flyman. Luckily, none of those titles made it. Eventually, he hit upon “Spider-Man,” which sounded much cooler and more sensational. And through the collaboration of Steve Ditko, the gangly teenage hero with spider powers was created.

Peter Parker Wasn’t the Original Spider-Man in Marvel Comics
Here’s a surprising twist: Peter Parker wasn’t exactly the first spider-themed character in Marvel history. Marvel had a tale featuring a ordinary spider that was exposed to radioactive rays in Journey into Mystery #73 (1950s). This beast evolved into a giant, intelligent humanoid spider who proclaimed, “I have become huge, powerful. The humans are my enemies.” He spun webs, ensnared individuals, and terrorized a facility before blowing up when hit with a missile. This was more of a monster story than a superhero story, but still—Marvel technically possessed a man-spider before Peter Parker ever swung onto the scene.
Peter Parker’s Sperm is Radioactive
Aye, you heard it right. One of the most shocking revelations in Spidey history happens in Spider-Man: Reign #3. In this darker alternate future, Peter clutches Mary Jane’s lifeless body and utters a terrifying truth: his radioactive body fluids—his sperm included—caused her cancer. In a ghastly monologue, he admits, “Loving me killed you… like a spider laying a thousand eggs of cancer.” It’s a chilling, emotional scene that’s as strange as it is sad. Not surprisingly, plenty of fans would like to ignore this specific plot point, but it’s canon within that world.
Spider-Man Once Wielded Thor’s Hammer
Peter Parker has gone by many monikers, but “God of Thunder” may be the craziest. In Marvel Action Classics: Spider-Man #2, there is an alternate universe Spidey who becomes worthy of Mjolnir. Having foiled a mugger who attempted to steal a necklace from the Enchantress, he is rewarded by being taken to Asgard by her. There, she grants him Thor’s powers, including hammer. Of course, this involves a confrontation with actual Thor. Even though it was a misrepresentation and Peter was deceived, the tale provides a snapshot of what life would be like if Spidey was granted divine power.

He Has the Most Nicknames in the Superhero World
Batman may be the Dark Knight and Superman may be the Man of Steel, but Spider-Man wins the nickname contest hands down. His roster is long: Spidey, Webhead, Wallcrawler, Webslinger, Bug Boy, Tiger, Arachnid Avenger, and of course, your friendly neighborhood Spider-Man. There’s even “Midtown High’s Only Professional Wall Crawler.” The sheer range is testament to his wide popularity and the various tones Spidey tales can have—goofy to gritty.
His Webs Disappear Within Two Hours
Ever ask yourself why New York isn’t covered in sticky spiderwebs? Well, Peter Parker did. According to Marvel, Spider-Man’s webbing fluid will break down within two hours. The webs begin to disintegrate due to built-in esters that degrade the solid strands to powder. So when Spidey swings off or captures a crook, the mess won’t last. It’s a brilliant approach to keeping things organized and the reason that the city doesn’t resemble a spider-themed horror house.
Peter Wasn’t the Lone Bite Victim of the Radioactive Spider
Decades ago, the general perception among fans was that Peter Parker was the only one to receive that infamous radioactive spider bite. But in The Amazing Spider-Man #1 (2014), Dan Slott shocked readers with an unexpected twist. As the flashback shows, the spider that bit Peter didn’t perish right away—it crawled off and bit someone else on the foot: Cindy Moon. Like Peter, she developed spider abilities and went on to become the hero called Silk. The revelation shook everything we believed about Spider-Man’s origin and introduced a fascinating new character to the Spider-verse.

A Monster Story Helped Pave the Way
Though not a direct lead-in, the spider-humanoid from Journey into Mystery #73 demonstrated that Marvel had already experimented with spider-based transformations long before Peter Parker’s first appearance. The creature was a product of a radioactive experiment and behaved more like a horror monster than a hero. Nevertheless, it’s intriguing to consider the possibility that the seed of Spider-Man had already been sown in those early monster comics Marvel was pumping out prior to their superhero heyday.
Spider-Man’s Story Keeps Evolving
From alternate universes and bleak futures to lost bites and explosive nicknames, Spider-Man’s history is teeming with odd, tragic, and astonishing facts. It’s what makes him such a deep character. He’s not only the boy who was bitten by the spider—he’s an icon of tenacity, nuance, and occasionally strangeness. Whether he’s swinging through Manhattan or grappling with radioactive love, there’s always something new to discover about Spider-Man.
