- "But Vasi is not normal. He likes sick things. He can command a Shamed One to do things that no true caste would ever do, or want to do, or want done."
- ―Uunu about Vasi
Vasi was a warrior of the Yuuzhan Vong. A slavemaster, Vasi was in charge of the slaves, Workers, and Shamed Ones on Yavin 4. Vasi was sadistic even by Yuuzhan Vong standards. He also had no problem engaging in sexual relations with Shamed Ones (deviant behavior on a number of levels in Yuuzhan Vong society) and seemed to have a particular attraction to a Shamed One named Uunu.
