Update: The second trailer for Captain Marvel has revealed that the titular hero’s cat is indeed in the movie… but it looks like the pet has a new name that’s different from the one in the comics.
In the new trailer, we see Nick Fury look at the cat’s name tag, which says “Goose” — obviously a Top Gun reference, considering Carol Danvers is an ex-fighter pilot herself.
