"What do you let him lick you like that for? Gross!"
Howard the Duck to the Collector[src]

Cosmo is a dog and a resident of the Knowhere mining colony.


Inside the Collector's Museum

Cosmo growling at Rocket Raccoon

Cosmo was a specimen from a U.S.S.R. space program and was brought to Taneleer Tivan's museum as a part of his obsession with collecting. When the Guardians of the Galaxy brought the Orb to Tivan, Rocket and Cosmo growled at each other and bared their teeth as Carina told them about Tivan's collection.

When Carina unleashed the Orb's power, destroying much of the museum, Cosmo managed to survive the catastrophe and escaped but didn't leave the museum.[1]


Cosmo licks Taneleer Tivan's face

Shortly afterwards, while Tivan, who also managed to survive, sat in the ruins of his museum, Cosmo returned to lick his face, as Howard the Duck commented that it was gross.[2]





  • In the comics, Cosmo was a test animal of the Soviet Space program. He was launched into Earth's orbit as part of an experiment in the 1960s but drifted off into space. He later arrived on Knowhere and became mutated, gaining telepathic and telekinetic abilities. The very uneasy relationship Cosmo has with Rocket Raccoon is referenced in the film when they growl at each other as the Guardians enter the museum.
  • Cosmo was created as a Marvel character loosely based on the real life story of Laika, who was a Russian dog that was sent into space to test whether it was possible for humans to survive the launch and conditions of outer space.
  • Cosmo has a cameo in the end-credits sequence of Guardians of the Galaxy Vol. 2.
