When Superman was still a baby on the doomed planet Krypton, his father Jor-El built a rocket to safely transport the infant to Earth. While testing a prototype, Jor-El sent Krypto, the family’s puppy, into space. Unfortunately, the spaceship was knocked off course and it drifted aimlessly for years. When it finally reached Earth, Krypto was reunited with Superboy, the last surviving member of his family.
Krypto was a popular addition to Superman’s childhood adventures, although in their initial encounters the playful pet with superpowers ended up being more trouble than anything else. Fortunately for Superboy, his dog liked to romp around the universe far from home, keeping him from being a nuisance on Earth for long stretches of time.
He eventually became a reliable ally for the Boy of Steel and although he couldn’t talk, thought balloons revealed that he could think as clearly as any human. In addition to frequent appearances as a supporting character in tales about Superboy, Krypto regularly headlined his own adventures and occasionally turned up in stories after Superman had grown up. He was even featured on the Saturday morning Superboy cartoon from 1966-1969. All this notoriety for a superhero’s super pet was not that surprising given the kitschy comics environment of the 60s.
