Goose is the beloved pet of one of the films main characters, Carol Danvers. Carol made her DC debut in a Marvel superheroes comic way back in 1968. Since then she's appeared in both Captain Marvel and X-Men comic books, using her superhuman strength and "seventh" sense to fight off a host of bad guys.
A cat by any other name...
In the comics, Carol Danvers' pet cat is actually called Chewie. Producers renamed the cat goose as a nod to the 1980s blockbuster Top Gun.
But whatever his name, fans are absolutely loving this little ginger superstar. So much so that Marvel has given Goose an official character poster.
Comments from fans include, “not the hero we need, BUT the Hero We Deserve” and “#GooseTheCat should have a stand-alone movie.”
Twitter has even created a special emoji for #Goosecat.
Movie reviewers have also responded positively. In her article for Insider magazine, Kirsten Acuna writes that Goose "popped up unexpectedly at just the right moments on screen" and noted that the “obsession with the feline is infectious.”
A star is born
Goose has even been honoured with his very own action figure and also appears on lines of Captain Marvel apparel.
Some fans might be surprised to learn that Goose is played by four different cats. Their names are Archie, Gonzo, Rizzo, and Reggie.
Reggie recently attended the LA premiere and even donned a little kitty tie for the occasion.
The cat also made an appearance in London where he met excited fans. Some of them managed to get an autograph from Reggie, although it's been described as more of a "pawtograph."
No animal has ever won an Oscar for the best supporting actor. Maybe Reggie or one of his pals could be the first!
