A Zygerrian slavemaster who led the slaving operation on Kadavo, Agruss delighted in his superiority over his pathetic charges. Agruss flaunted his power freely, punishing and executing slaves at a whim to ensure no one every questioned his authority. The overweight Zygerrian hovered aloft on a repulsorlift chair, exuding an air of decadence. Agruss particularly delighted in tormenting Obi-Wan Kenobi, the first ever Jedi to be interred at his grueling facility.
