Disambiguation: Clark Kent / Kal-El

First published in: 1938

Decades ago, the planet Krypton exploded. Moments before that happened, a scientist named Jor-El and his wife Lara (sometimes Lora) placed their toddler son, Kal-El, in a small rocketship and sent him into space. The craft landed in a field outside of the rural town of Smallville. A couple named the Kents witnessed the crash and found the child inside, completely unharmed. They named him Clark and adopted him as their own son. The Kents soon discovered he possessed remarkable powers, and concluded that they should keep it a secret. When Clark was a young boy, he donned a colorful costume and became the hero named Superboy. When he reached adulthood, Clark changed his codename to Superman. Clark Kent became a reporter in the city of Metropolis, where he met and fell in love with fellow reporter, Lois Lane.

Superman's powers include: invulnerability, super-strength, flight, super-speed, super-senses (x-ray, telescopic, microscopic, and infrared vision; super-hearing; super-smell; super-taste; super-touch), heat vision, super-breath and freeze-breath, super-hypnosis, faster-than-light space-travel, and time-travel.

Superman's weaknesses include: green kryptonite (pain and weakness, followed by death), gold kryptonite (permanent loss of powers), red kryptonite (unpredictable effects), red solar radiation (loss of solar-based powers), high gravity (loss of gravity-based powers), and magic.

Superman's nicknames include "The Man of Steel" and "The Man of Tomorrow".

Superman was created by Jerry Siegel and Joe Shuster.

It is a common misconception that the Golden Age Superman's birth name was Kal-L. This name appeared in the newspaper strip (see January 17, 1939), but was not used in comic books until the introduction of the Superman of Earth-Two in 1969. See separate character record for the Superman of Earth-Two.

In the comics, Clark's adoptive father was given the names John, Silas and Jonathan, while his adoptive mother was given the names Mary, Marthe and Martha. In The Adventures of Superman radio program (1940), Clark's father was Eben Kent. In George Lowther's novel, The Adventures of Superman (1942), his parents were Eben and Sarah Kent. In the Columbia Pictures film serial Superman (1948), they were Eben and Martha Kent. In The Adventures of Superman television show (1952), they were Eben and Sarah Kent. Clark's parents were never referred to as Eben and Sarah in the comics.

Clark Kent's birthday, June 18, was derived from the birthday of Bud Collyer, the voice actor who played Clark Kent and Superman in the radio program from 1940 to 1950 and in animated cartoons in the 1940s and 1960s.
