Geass (or Geas) is a term used in Irish Mythology that means 'contract' or 'vow'.
Code Geass is one of the most popular anime
series around the world, but Sunrise expected it
to be a failure.
Code Geass has one full length anime adaptation, however there are four different manga adaptations as well as three games based on it. two spin off OVAs, and a film version of the original series, with other plans in the works.
Lelouch's original character design was meant to have white hair.
The basic idea for the plot consisted of a
"hero" who led a secret organization, which was
later developed into a conflict between two
characters with different values and who
belonged to the same military unit, who
eventually became Lelouch Lamperouge and
Suzaku Kururugi.
