Who Voices Cosmo In The Guardians Of The Galaxy Holiday Special?

Cosmo the Spacedog makes its Marvel Cinematic Universe debut in the first "Guardians of the Galaxy" movie as one of the Collector's (Benicio Del Toro) precious collectibles, along with fellow talking animal hero Howard the Duck (voiced by Seth Green). However, unlike Howard, Cosmo never actually utters a (telepathic) word onscreen, leaving it open whether this version of the adorable spacefaring mutt has the same powers as its comic book counterpart.

James Gunn's new "The Guardians of the Galaxy Holiday Special" on Disney+ corrects this glaring error by confirming that Cosmo is indeed able to communicate in its famous fashion. However, unlike most versions of the character, which have been portrayed as male, this Cosmo is very decidedly a lady. The decision makes plenty of sense, since Cosmo's obvious inspiration and one of the most famous dogs in history, Laika, was female. It also helps that the character's voice actor does a stellar job, giving the dog a boost of personality that bodes well for the character's MCU future. Let's take a look at who's voicing Cosmo in "The Guardians of the Galaxy Holiday Special," and why she might sound quite familiar.
