How a Scrappy Indie Comic Blew Up into a Multi-Billion Dollar Empire—And Tore Two Best Friends Apart

Kier

In 1984, two best friends were sitting in their unfurnished slum of a house, watching cartoons and drawing comedy comic strips to entertain themselves. One friend sketched out a Turtle standing on two legs with a head wrap and a pair of nunchucks. He showed his buddy, who added a few things to the sketch and wrote a name on it.

That name was Teenage Mutant Ninja Turtles.

There are few single years in history as significant in pop culture as 1984. It’s the year we met The Ghostbusters, the year Mr. Miyagi taught Daniel LaRusso to defeat his bullies, and the year The Terminator blasted his way onto the big screen. But tucked away in a shared home in New Hampshire, a small indie comic about four turtle siblings was conceived—soon to take the entire world by storm.

What started as a dark, gritty parody of popular superheroes quickly proved to be a viable property. It left its creators to face levels of fame and success that would eventually drive them apart, all while their creation became bigger, and bigger, and bigger.

The Secret Origin: A Parody of Marvel’s Daredevil

The Teenage Mutant Ninja Turtles were created by the now-legendary duo of Peter Laird and Kevin Eastman. As lifelong comic book fans trying to break into the industry, neither had achieved success with the big two publishers of the time: Marvel and DC.

The original TMNT concept was actually a direct parody of one of Marvel’s most famous heroes: Daredevil.

In Marvel lore, young Matt Murdock is blinded after saving a civilian from a truck crash, resulting in toxic waste splashing into his eyes. Eastman and Laird imagined that that same “ooze” trickled off the street into the sewers, infecting four regular turtles and a sewer rat. The ninja aspect was also pulled from Daredevil; instead of fighting his sworn enemies, “The Hand,” Eastman and Laird named their villains “The Foot.” Their sensei, Splinter, was a clear play on Daredevil’s mentor, Stick.

Knowing they had something unique, they scraped together all the money they had and released the first issue independently under the name “Mirage Studios”—which was really just the two artists in their living room. They printed 3,000 copies. They sold out instantly.

1987: The Billion-Dollar Toy Deal and “Turtlemania”

While the original comic run was a grimy, colorless tale of violence and corruption, the turtles we know today were forged in 1987. Eastman and Laird inked a deal with Playmates Toys to produce action figures.

To make the property viable for kids, the rougher edges were softened. The turtles received colorful masks and cuter designs. The pivot worked beyond anyone’s wildest dreams: the line sold over $1 billion worth of action figures between 1987 and 1989.

This highly lucrative empire was being managed entirely by just two guys without editors, managers, or staff. Soon, the toys weren’t enough. Enter the iconic animated series.

But the cartoon became the catalyst that drove the friends apart. Eastman and Laird were dreamers who passed unfinished comic pages back and forth until they were perfect. The overwhelming pressure of “Turtlemania” stripped away the fun. By the time the animated series premiered, the creators barely spoke and almost never worked collaboratively. The creation was thriving beyond their wildest expectations, but the friendship was in shambles.

Hollywood Calls: The Legacy of the 1990 Film

In the late 80s, B-movie legend Roger Corman approached the boys about a film that would have seen actors like Billy Crystal painted green. Fortunately, that version fell through, paving the way for the legendary 1990 New Line Cinema live-action movie.

Jim Henson was hired to create the revolutionary turtle costumes—the single biggest undertaking of his career. Henson’s team built fully practical suits out of foam, clay, and rubber, equipped with movable animatronic eyes and facial muscles. The way these characters caught light and performed stunts added a tangible magic that CGI still struggles to replicate.

The film blended the grit of the original comics with the humor of the cartoon. Despite its quality, major studios like Disney, Paramount, Fox, and Universal all passed on distributing it. New Line Cinema finally picked it up, releasing it to a staggering $200 million global box office haul on a tiny $13 million budget.

The Sequel Peak and the 1993 Downfall

Just one year later, Ninja Turtles II: The Secret of the Ooze (1991) hit theaters. It serves as the absolute pinnacle of TMNT cinema for many fans. The comedy was ramped up, the action hit harder, and pro wrestler Kevin Nash stepped into the muscle suit as Super Shredder. It also featured arguably the best-looking movie pizza in cinematic history.

Though highly successful, its $80 million gross was a drop from the original, making a third installment a financial necessity.

TMNT III (1993) arrived as a massive downgrade. The plot sent the turtles back in time to ancient Japan, but Turtlemania was dying down, and the ongoing feud between Laird and Eastman meant no new comic source material was being produced. Combined with visibly lower-quality animatronic suits, the film looked cheap and stalled the live-action franchise indefinitely.

The Final Split and The Last Ronin’s Redemption

Throughout the 90s, the creators’ collaborative clashes grew worse, leaving readers detached. By the year 2000, Kevin Eastman had finally had enough of the drama and sold his 50% stake of the franchise to Peter Laird, making Laird the sole owner. While the property continued through various reboots—including the Michael Bay films and the excellent Mutant Mayhem—the original creative spark was fractured.

Then came 2022.

After years of estrangement, the duo buried the hatchet for one final ride: The Last Ronin.

This dark, heartbreaking comic picked up straight from the original 1984 continuity, ignoring all other timelines. It follows a lone, anonymous ninja turtle attempting to survive after his brothers and sensei are murdered. It was eventually revealed that this lone survivor was Michelangelo—the silliest, least likely member of the team to survive.

Many fans believe the poignant monologues scattered throughout The Last Ronin are Eastman and Laird’s real-life way of making amends, using their final masterpiece to heal the relationship that their own billion-dollar empire originally destroyed.
