Andronikos Revel is the second companion character of the Sith Inquisitor - a male bounty hunter and assassin obtainable once the player has progressed the Inquisitor story missions to the beginning of Tatooine (after Nar Shaddaa). He is preferred over Khem Val by some Sith Assassins, due to his damage output. However, Khem Val is still the superior tank. You can acquire Andronikos' customization for 12500 credits from Keth, the Customization vendor at the Brell Sediment, Taris.
