Superboy-Prime is from the universe known as Earth Prime, in which the DC heroes are fictional comic book characters. He is the adopted son of Jerry and Naomi Kent. Naomi wanted to name their infant son Clark, after her maiden name, but Jerry, knowing he will also be named like Superman, a fictional comic book character, initially refused, but finally gave in. What the Kents do not know is that the baby, found abandoned in a forest, is actually a young Kal-El, who has been teleported to Earth by his father Jor-El moments before the planet Krypton was destroyed when its red sun went supernova. His parents were unable to escape that way due to a member of the Kryptonian council bursting into the room and using the device, although it is unknown what happened to him.
