In its first appearance, Krypton was only depicted at the moment of its destruction. Beginning in the ''Superman'' [[comic strip]], Krypton was shown to have been a planet similar to Earth, only older by eons and possessed of all the [[Progress (history)|progress]] that implied. It is suggested that Krypton exploded due mainly to old age and the massive use of electricity Kryptonians used for their technology.

The debut of the ''Superman'' newspaper comic strip in 1939 delved into further details about Krypton, introducing the idea that all Kryptonians possessed a level of heightened physical abilities, including [[Superhuman strength|super-strength]] and super-speed. In the early comics' version of Krypton, [[Superman]]'s parents were named "Jor-L" and "Lora", though their names were changed to the more familiar "[[Jor-El]]" and "[[Lara (comics)|Lara]]" by the end of the 1940s.

The [[Golden Age of Comic Books|Golden Age]] Krypton would be revised into another form almost as soon as it was defined, and very few stories were initially written about it. After the introduction of [[DC Comics|DC]]'s [[Multiverse (DC Comics)|multiverse]] in the 1960s, this version of Krypton was declared to be the Krypton of the [[Multiverse (DC Comics)#Catalogued Earths|Earth-Two]] universe; the native dimension of DC's [[Golden Age of Comic Books|Golden Age]] characters and its Superman.

After the emergence of Earth-Two as a differentiated alternate universe within the DC Multiverse, [[Power Girl]] (Kara Zor-El) was introduced as Krypton-Two's alternate [[Supergirl]] in 1976. Kal-El and Kara Zor-El were the only known survivors of Krypton-Two, unlike the Silver Age analogue. Earth-Two's universe lacked its own [[Brainiac (character)|Brainiac]], so its Kandor was never abducted from Krypton Two before its destruction, nor did Kal-El have his own version of [[Krypton]] as an infant and toddler on this world.

In the Golden Age, Superman was initially unaware 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 (Kryptonian)|Mala]], who were exiled by Superman's father before Krypton's destruction.
