A particularly angry Trandoshan on his way to prison
Niss Pewdoc was a trandoshan that was somehow subdued by Imperial Stormtroopers after going on a rampage in Phelar. His manifest states that he assassinated an Imperial Officer and then turned on a patrol of normal Imperial Army Troopers.
When a Lambda Class Shuttle engaged the transport and cut off power to the prisoner area, Niss escaped. He immediately engaged Yuundar and the heroes on multiple occasions before being killed by Marlem.
