So Cosmo is basically the Russian dog that was brought to space by the Soviets. Cosmo also has a thing that allows it to telepathically speak. So when it comes to the video game and the series that’s more kid friendly Cosmo is a boy. According to the movie Cosmo is a female. But what would be the most correct view according to the comic books? I would imagine considering the most common depiction is male. I also think that Cosmo is somewhat inspired by Laika being a female dog. Maybe the sex of Cosmo in the comics is more ambiguous and I can get that as well. But if anyone has read the comics does anyone know for certain?
It seems the “default” depiction of Cosmo is male, but was female for the movie. Perhaps James Gunn wanted to try something different?
Cosmo is also female in the videogame. Also, Cosmo is based on Leika, the first dog (an living animal in general) in space and she was a female dog too.
