Early Life[]

Superman was born Kal-El before being rocketed to as an infant by his scientist father Jor-El moments before the home planet Krypton was destroyed. Discovered and adopted by the Kents, the child is raised as Clark Kent in Smallville and imbued with a strong moral compass. Very early he started to display superpowers, which upon reaching maturity he resolved to use for the benefit of humanity.

Superman is a founding member of the Justice League of America who rivals Batman and Wonder Woman.

Superman is Leonard Hofstadter's favorite superhero and his birth name Kal-El is his most common computer password. He also wears "Clark Kent"-style glasses.

Sheldon tells her that she is travelling so fast that when Superman's arms of steel caught her, she would be sliced into three equal pieces.

In "The White Asparagus Triangulation" (S02E09), Sheldon hacks into Leonard's Facebook account which is easy since he always used the same password, Kal-el, the Kryptonian name for Superman.

In "The Bath Item Gift Hypothesis" (S02E11), the group discuss what Superman does when he sweats. The scenario includes him visiting the bottled city of Kandor and engaging in a game of Kryptonian tether ball. He then had to find a Kandorian dry cleaner before he returned to Earth.

In "The Good Guy Fluctuation" (S05E07), Alice, a comic book store customer, asks if she can flirt with Leonard and distract him to get a rare comic book. Leonard says that she can, but she would be using her superpowers for evil. She replies referring to Superman: I'm forbidden by my Kryptonian father to do so. On the side, in 1982, the actress' husband Brandon Routh played Superman in the movie "Superman Returns".
