CLU 2

CLU 2 (shortened to Clu or CLU which stands for Codified Likeness Utility 2.0) is an artificial intelligence program that was written in 1983 by Kevin Flynn. Clu is the main antagonist of TRON: Legacy, the secondary antagonist of TRON: Evolution and the central antagonist of TRON: Uprising. As with most programs, Clu appears visually identical - albeit at a younger age - to his creator. He represents an evil digital doppelgänger of Kevin Flynn and a twisted embodiment of Flynn's youth. He is addressed as "Your Excellency" by various characters.
