Krypton is a destroyed planet in the My Adventures with Superman universe. It was the home of the Kryptonian race, including Clark Kent, Kara Zor-El and the rest of their family. It was destroyed by their own creation known as the Brainiac system for negotiating a peace treaty with their last enemies.
With their planet was destroyed, the species were all but massacred with the exception of two; the children of House El, Kal and Kara, who were sent away by their respective fathers in order to escape the annihilation. Brainiac then used derelict Kryptonian warships and technology and manipulated it with the intention of starting a campaign of conquest.
The only remaining piece of Krypton was the capital of Kandor, which survived in the form of a space station.
