The most familiar face of the Super Family is Kal-El, who is known as Clark Kent on Earth. He was sent to our planet as a child by his parents to escape the destruction of Krypton. Growing up on a Kansas farm, he learned all the values that would serve him well as the Man of Steel - first as Superboy and later as Superman. Soon he would be joined by another Kryptonian, Kara Zor-L, who claimed to be his cousin. it was revealed that she was actually from an alternate reality that had been wiped out in a transdimensional cataclysm. Regardless, Clark welcomed her as family and she took on the identity of Karen Starr, aka Supergirl.
Tragedy struck when the mysterious villain known as Doomsday rampaged across the United States. Few knew that Lex Luthor had created a genetic hybrid containing both DNA from the Hulk and General Zod. Almost unstoppable, it was only defeated by the sacrifice of Superman. Thought to have perished, several new heroes arose to succeed him - the young Teen Superman, the violent Last Son of Krypton, the armored Man of Steel, and the cyborg Man of Tomorrow.Eventually, Kal-El returned to life after spending time in a regenerative coma, taking back the mantle of Superman. Teen Superman then became the modern Superboy, the Last Son of Krypton is revealed to be the Kryptonian android Eradicator, and the Man of Tomorrow is revealed to be the villainous Hank Henshaw, the Cyborg Superman.
Not long after Superman resumed being a hero, another Kryptonian starship crash-landed in the waters between Metropolis and Gotham. There Kal-El was greeted by his real cousin Kara Zor-El. Kara was technically older than Kal when she left Krypton, but due to an anomaly in the Phantom Zone drive, she ended up on Earth decades late. After some reconnecting with Clark and her alternate universe counterpart, Kara Danvers took on the mantle of Supergirl. Karen Starr then became the hero known as Power Girl.
Centuries ago, after the attempted coup against the Science Guild, the Military Guild found itself relegated to the status of a minor guild, denied the funding required to maintain its previously massive army. Withering under the mandates of the Lawmakers Guild, a faction of soldiers formed a group dedicated to returning Krypton to its former glory - the Sword of Rao. Led by General Zod, his confederates attempted to overthrow the ruling council but were stopped by loyal soldiers from the Military Guild. Convicted of sedition, they were sentenced to life in the Phantom Zone. Years later an interdimensional accident freed Zod, his wife Faora, and his trusted lieutenants on Earth. Since then, they have been a thorn in the side of Kal-El who must continually think of new ways to defeat and imprison his foes.
A few others also managed to escape the destruction of homeworld but like Zod, are inextricably linked to the House of El: The genetically-altered soldier known as Reign who had been created by the Military Guild as a secret weapon; the chimeric survivor known as H'El, who set out on a crusade to create a New Krypton; and Zor-El the father of Supergirl who was rescued by Brainiac and turned into his Herald, becoming what would later be known as the second Cyborg Superman.
