Ash hates the Legion of Super-Pets story, so perhaps he’s not a hopeless case. Even though Superboy/Superman/Clark Kent was supposedly the only survivor from his planet, a menagerie of animals managed to make it to Earth as well. There’s Krypto, the Superdog, who is a Superman’s best friend. There’s also Supercat, Superhorse, and Supermonkey. Apparently the monkey stowed away on the spaceship with Superbaby Clark Kent. I guess there was room for a monkey, but not his own mother.
Anyway, the story in the Legion of Superheroes Archives Volume 1 begins with giant, evil, floating brains. The brains attack the planet, and they can control human brains. The big brains can’t control animal brains, which means that the Super-Pets are able to save the day.
