In an early version of the script, there were four Kryptonian exile villains instead of three. The fourth member, Jak-El, was supposed to be an evil prankster and source of comic relief (a similar character to Riddler in the Batman series). In an early script, he is described as 'A psychopathic jokester, whose pranks and "practical jokes" are only funny to him when they cause death and suffering to others, this is JAK-EL.' The character was later dropped and never cast.
