The central character and primary protagonist of the movie, Revan's life has been long and complicated. Originally a Jedi, he left the Order to fight in the Mandalorian Wars, after which he travelled to Drommund Kaas, fell under The Emperor's influence, and became a Sith Lord. Several years later, a betrayal from his apprentice left Revan near death, and the Jedi Council erased his memory of his fall to the Dark Side, rendering him a Jedi once more. Despite this, Revan's memory is starting to return, and his relationship with the Jedi Order remains frosty: having shunned both the light and the dark, Revan exists as a character whose loyalties and powers are atypical; his experience of being both a Jedi and Sith gives him incredible strength, but he fights only for the safety of his family and the galaxy at large, foregoing the philosophical dogma that drives many of the other characters.

Revan usually speaks in a calm, even manner and is rarely angry. He also occasionally lapses into moments of self-doubt and disillusionment.
