We almost lived in a world where we played “Build On” or “Funny Kong” instead of the arcade classic we know today. New legal archives from 1983 have revealed new information about Nintendo’s most pivotal era, revealing that the world’s most famous gorilla wasn’t even meant to be an animal at all.

The history of video games is often written by the victors, but rarely do we get to see the messy, creative brainstorming that happens before a legend is born.
A massive 1.3GB archive of court documents from the infamous 1983 Universal City Studios, Inc. v. Nintendo Co., Ltd. lawsuit has recently surfaced, offering a rare, unvarnished look at Shigeru Miyamoto’s original vision for Donkey Kong.
From Miyamoto’s personal preference for a title that sounded more like a construction manual to the bizarre revelation that the giant ape was technically a man in a costume, this discovery is a goldmine for digital historians.

“Build On” and “Kong Chase”: The Titles That Failed?
Shigeru Miyamoto’s brainstorm for the 1981 classic was far more literal than the name we eventually got. Documents show his personal favorite was actually Build On, a direct nod to the construction site setting. Other rejected contenders included Kong Chase and Attack of the Kong.
While we know the “Donkey” in the final name was meant to convey “stubborn” to English audiences, these archives show just how close we came to a completely different brand.
It highlights a time when Nintendo was still finding its footing in the West, experimenting with titles that sounded more like generic action phrases than iconic characters.
The Gorilla Suit Secret: Miyamoto’s Original Vision?
The biggest bombshell, revealed by Norman Caruso of Gaming Historian, and who we havbe to thank for the new information, is the description of the character’s physical nature. Donkey Kong is described as “a human being wearing a stuffed doll,” essentially a mascot in a costume.
This “man-in-a-suit” concept explains why the character has always been so expressive. Unlike other early 80s sprites that felt like static obstacles, the big ape had smirks and clear physical reactions.
He wasn’t designed to be a realistic wild animal. He was a performer, which gave him a personality that has endured for over forty years.
A Legacy Saved by a Lawsuit?
These documents, recently released by historian Norman Caruso, provide a rare look at a moment when Nintendo was fighting for its life. The Universal vs. Nintendo case was the ultimate turning point.
Had Universal won that legal battle, Donkey Kong, and the very foundation of Nintendo of America, might have vanished.
