Before he was a character, Venom was a costume.

Imagine if the Joker started out as a clown outfit that Batman wore for circus-themed missions and you’ll have some idea of just how odd the path that this character took to antihero superstardom really was.

Back in 1982, comics reader Randy Schueller submitted an idea to Marvel for a storyline in which Spider-Man acquired a black costume (with a red spider logo, rather than the familiar white one) made of “unstable molecules,” i.e. the Marvel Universe material from which the Fantastic Four’s Reed Richards made his team’s uniforms. More than mere fabric, this outfit would be able to adjust to Peter Parker’s needs, as well as enhance his powers. Controversial Marvel editor-in-chief Jim Shooter bought the idea from Schueller for a cool $220.

It took a couple of years for the new white-on-black look to make its first chronological appearance in the pages of the company-wide crossover “event comic” Secret Wars #8, courtesy of a design by artist Mike Zeck and a script by Shooter that saw the Webslinger acquire the costume on an alien planet.

Though the issue came out in December 1984, the costume had popped up several months earlier — first as a sketch in March’s comic-length newsletter Marvel Age #12, then in a Spidey story set after the events of Secret Wars in May’s Amazing Spider-Man #252, plotted by Roger Stern, written by Tom DeFalco, and illustrated by Ron Frenz.

… And also an alien parasite.

During their Amazing Spider-Man run, DeFalco and Frenz fleshed out the origin of the liquid-like black outfit, which would respond to Peter Parker’s thoughts; it would even hijack him in his sleep for late-night crimefighting binges. Sure, it looks badass, but it’s not merely a futuristic crimefighting costume or the self-repairing clothes writer/artist John Byrne had devised for the martial-arts hero Iron Fist (an influence on Stern’s concept for the costume). It’s a sentient, symbiotic alien entity, one which bonds to a human host and bestows them with incredible powers while still maintaining a mind of its own.

That “mind of its own” thing is the rub. Though he digs the power-up, Parker quickly learns that this “Symbiote” wants to bond to his body permanently. By exploiting the alien’s vulnerability to fire and sonic energy — and with a little help from the Fantastic Four — Spider-Man separates himself from the costume, which slithers off to find another host to inhabit.

I wrote a quick cheat sheet to catch people up on the history of Venom in comics and film, just in time for the new Tom Hardy movie, for Rolling Stone. I like doing pieces like this because it’s a way to give some shine to the writers and artists who made this multibillion-dollar industry possible.
