Bat-Mite is a member of a sentient species of the Chiroptera family presumably descended from bats. His species lives in a remote region of the Andes as yet unvisited by humans.

When Bat-Mite wandered into human civilization, he learned of Batman. Impressed by his prowess and his adventures, he became a major fan. Unfortunately he also became a major nuisance.

Members of his species are notorious for poor eyesight and rely on sonar to navigate and experience three dimensional space. To compensate, Bat-Mite wears prescription goggles.

Krypto has been Superman's furry companion since he was an infant on the planet Krypton. Although they are not as intelligent as humanoids, Kryptonian dogs can read minds, even if they cannot project their thoughts.

Krypto was paired with the infant Kal-el to mind him and keep him from harm, which was a common practice on Krypton, and was sent with Kal-el to Earth AI for that purpose.

Kryptonian dogs live hundreds of years, which explains how Krypto could have been a puppy when Kal was a baby and still be alive now that Superman is in his thirties.
