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?
Yes.
