Breaking: Captain Marvel’s Cat Appears On The ‘Captain Marvel’ Poster
Extremely important breaking news: Captain Marvel’s cat Chewie appears on the newCaptain Marvelposter. The poster arrived today along with the exciting trailer, and eagle-eyed folks online have already spotted the tail-end of Chewie the Cat – who isn’t actually a cat at all, but actually a cat-like alien known as a Flerken. I swear I’m not making any of this up!
By now, you’ve likely watched theCaptain Marveltrailer, which dropped today, along with this poster:
On the surface, this looks like your standard Marvel poster. Hero standing front and center, digitally rendered backdrop, tagline at the ready, and so on. But wait, what’s that strange object on the left-hand side of the poster? Shrouded in the darkness? A Twitter user has the answer.

That’s right, folks: it’s a cat’s butt. What’s going on here? Did someone over at Marvel cheekily insert a random cat just for a laugh? Maybe! Or maybe there’s more to this than meets the eye. In the comics, Captain Marvel, AKA Carol Danvers, actually has a cat – named Chewie. But Chewie is no mere cat. He’s actually a Flerken – an alien species that just happens to resemble cats. Flerkens come equipped with the following powers (via theMarvel Wiki):
Pocket DimensionsThe species are said to be able to store entire universes within their mouths, with which they can access and store a great many of things within to draw upon at will.
Human intellect: able to understand cognitive conversation.
In the comics, Rocket Raccoon was the first to realize that Carol’s cat was indeed a Flerken – something Carol herself doubted, until Chewie ended up laying some eggs. Chewie doesn’t appear in theCaptain Marveltrailer, so it’s not clear if the alien feline will actually be in the movie, or if the creature was simply inserted into this poster as an easter egg for fans. But back whileCaptain Marvelwas filming,Samuel L. Jacksonposted a pic thatalsoteased the presence of Chewie. See for yourself:

Whether or not Chewie actually shows up inCaptain Marvelremains to be seen. If so, though, I hope this leads to the inevitable Rocket Raccoon/Chewie spin-off movie. It’s what we deserve.
