A female version of Cosmo the Spacedog appeared in a cameo role in the Marvel Cinematic Universe films Guardians of the Galaxy (2014) and Guardians of the Galaxy Vol. 2 (2017), as well as in the Disney+ animated series What If...? (2021). She is voiced by Maria Bakalova in The Guardians of the Galaxy Holiday Special (2022) and Guardians of the Galaxy Vol. 3 (2023).
Fictional character biography Cosmo was a Soviet space dog during the 1960s and was launched into Earth's orbit by the Soviet space program as part of an experiment. Cosmo was lost in space and mutated by exposure to cosmic rays, gaining psychic powers. Eventually, Cosmo landed on Knowhere, a city located within the severed head of a giant Celestial, and became Knowhere's security chief.Nova (vol. 4) #8 (January 2008)
Nova meets Cosmo shortly after encountering Suspensor, who he kills in self-defense. Cosmo and Nova are ambushed by a group of zombies, including the surviving members of Suspensor's former team, the Luminals. The two determine that Abyss was responsible and seal him away.Nova (vol. 4) #9 (February 2008)
Peter Quill's original Guardians of the Galaxy team operated out of Knowhere for some time, thus dragging Cosmo into many of their exploits. During one such adventure, Cosmo and the Guardians bounce around the time stream in an attempt to stop the Fault, a tear in the universe, from eliminating all of reality. During this adventure, Cosmo is de-aged into a puppy.Guardians of the Galaxy (vol. 3) #18 (October 2014)
During The Thanos Imperative storyline, the corrupted beings of the Cancerverse invade Earth-616 through the Fault. The Guardians of the Galaxy allied with Thanos to stop Mar-Vell. During the battle, Phyla-Vell is killed and Adam Warlock, Drax, and Star-Lord are presumed dead. At Star-Lord's request, Cosmo gathers Silver Surfer, Gladiator, Beta Ray Bill, Quasar, and Ronan the Accuser to protect the universe together.Thanos Imperative: Ignition one-shot (July 2010)
Cosmo is seen with several new Knowhere enforcement allies called the Knowhere Corps. They assist him in capturing a violence-loving gangster called Yotat.Guardians of the Galaxy (vol. 4) #5 (February 2016)
Powers and abilities In addition to a dog's standard enhanced sense of hearing and smell, Cosmo has psionic abilities, including high-level telepathy and telekinesis. He has shown to be capable of creating defensive shields strong enough to deflect energy blasts, as well as project mind blasts of tremendous force. His exact power levels are unknown, but he has shown to be strong enough to take on a being such as Adam Warlock by himself, and powerful enough to unleash a telekinetic blast able to disable two separate teams of super-humans.
In addition to these abilities, Cosmo seems to have a considerably extended lifespan as well — especially for a dog since he has been around since the time of the Soviet Union.
