A viral post on X is putting a spotlight on a problem that’s been building for years in the creative world — and this one’s hard to look away from.
An artist posting under the handle Kwok (@Kwokzisong) says their personal fan art — featuring David Corenswet’s Superman alongside a red-toned take on Robert Pattinson’s Batman — has been turned into a mass-produced party decoration set listed on Walmart’s website. Plates, cups, tablecloths, cake toppers. The whole spread. Priced at just over a dollar.
The artist says they never gave permission.
Hate to be a buzzkill on Superman Day, but Walmart turned my art into a product without telling me. Both of these drawings were personal practice pieces — never for commercial use. I just put them together for fun, not as an official thing. No idea how Walmart approved this. pic.twitter.com/GJIUq3fsdT

According to Kwok’s post, both drawings were personal practice pieces — never intended for commercial use. They were shared online casually, the way thousands of artists share work every day. But shortly after, those same images showed up on a product listing for a “Super Hero Birthday Party Decoration Set” sold through Walmart’s third-party marketplace.
And that’s where this gets complicated.
Walmart didn’t design or manufacture the product. Like Amazon, Walmart allows outside sellers — often overseas manufacturers — to list products on its platform. In this case, the seller appears to be based in China, with Walmart serving as the storefront and fulfillment layer. That distinction matters legally. But for most people scrolling Walmart’s website, it doesn’t matter at all. If it’s on Walmart.com, it feels like a Walmart product.
Then there’s the IP layer. The artwork itself is fan art based on characters owned by Warner Bros. Discovery. Kwok doesn’t own Superman or Batman. But they do own their specific artwork and interpretation. A third party taking that art and slapping it on products without consent is still a problem — even if the underlying characters belong to someone else. It’s a collision of corporate IP, individual authorship, and a global marketplace that doesn’t always respect either.
Some commenters online have also accused the art of being AI-generated, pointing to visual inconsistencies. Others have defended it, with the artist claiming to have process files and source layers. ComicBook.com noted that the apparent “AI tells” are actually just artifacts from cropping two separate images together. But the fact that authorship itself is now debatable says something about the moment we’re in. In 2026, proving you made something isn’t always straightforward — and when that uncertainty meets mass production, control gets almost impossible.
The speed is what makes this different from old-school bootlegging. A piece of art can be posted online, scraped, sent to a manufacturer, turned into a physical product, and listed on a global retail platform — all before the artist even realizes it happened. Kwok says they’ve contacted Walmart to have the listing removed, which is the standard first step. But even if this specific product disappears, the ecosystem that created it isn’t going anywhere.
For fans, it’s a weird curiosity. For artists, it’s a warning. And for the platforms hosting these marketplaces, the question keeps getting louder: at what point does “we’re just the platform” stop being a good enough answer?
