Boc appears as one of the final and most challenging boss fights in the game. He uses two lightsabers and makes frequent use of the Force Destruction ability, which is essentially a large, deadly fireball.
He is the final boss before moving on to face Jerec, the primary antagonist of the game. He had been guarding the captive Jan Ors, Kyle Katarn's friend and lover. Kyle then goes on to kill Jerec, stopping him from taking the power of the Valley of the Jedi.
