Guardians of the Galaxy Vol. 3
Elizabeth Debicki reprises her role as Ayesha, the golden High Priestess and the leader of the Sovereign people. In that role, she had Adam Warlock created to destroy the Guardians. Others who return in their roles from the Guardians movies and/or The Guardians of the Galaxy Holiday Special (2022) are Michael Rosenbaum as Martinex, Seth Green as the voice of Howard the Duck; Christopher Fairbank as the Broker; Stephen Blackehart and Rhett Miller as Steemie and Bzermikitokolok, two denizens of Knowhere; Gregg Henry as Quill's grandfather Jason; and Michael Rooker as Yondu Udonta, the former head of the Ravagers and Peter's deceased mentor. Maria Bakalova reprises her role as Cosmo the Spacedog, a member of the Guardians who is a sentient dog that developed psionic abilities after being sent into space by the Soviet Union. Gunn changed Cosmo's gender from male, as depicted in the comics, to female for the movie. This was made as a tribute to the character's original inspiration Laika, a Soviet space dog who became one of the first animals in space. In addition to voice acting, Bakalova provided motion capture for the character. Cosmo was physically portrayed by dog actor Slate, after doing so for the Holiday Special. The character was previously portrayed by dog actor Fred in the first two Guardians movies.
