10 Characters You Didn’t Know Exist In The MCU

That pooch dressed as a Soviet cosmonaut at the Collector's museum in Guardians of the Galaxy is a bigger deal than many moviegoers will have realised.

Cosmo the Space Dog is a Marvel Comics character of note, with various telepathic and telekinetic abilities heading up his lengthy list of superpowers. He's also fluent in Russian and able to hold his own in English.

This labrador-golden retriever hybrid was imbued with these gifts after being blasted into space as part of a Soviet space programme experiment. The craft he was placed on board drifted into deep space and was exposed to cosmic rays before arriving at Knowhere, the inter-dimensional crossroads where the Collector resides.

Cosmo is a long-time ally of Nova and has even spent time as an official Guardians of the Galaxy member in the comics, assisting the team on several adventures. With James Gunn planning to expand the cosmic elements of the MCU in the future, there's a good chance the space dog will be cropping up on screen again at some point.
