 Earth Two's universe lacked its own Brainiac, so its Kandor was never abducted from Krypton Two before its destruction, nor did Kal-L have his own version of Krypto as an infant and toddler on this world.In the Golden Age, Superman was unaware initially of his true origins; in "Superman" #61, Superman discovered the existence of Krypton for the first time and learned of his Kryptonian heritage.He later encountered other survivors prior to Kara's arrival in the form of three criminals, U-Ban, Kizo, and Mala, who were exiled by Superman's father before Krypton's destruction.
