- "Wullffwarro. I know that name. He was one of the Republic's greatest soldiers during the Clone Wars."
- ―Garazeb Orrelios
Wullffwarro was a male silverback Wookiee who was taken as a slave by the Galactic Empire. Prior to the rise of the Empire, Wullffwarro served alongside the Galactic Republic during the Clone Wars, and also fought in the Battle of Kashyyyk. Fourteen years after the Empire came to power, Wullffwarro and his son, Kitwarr, were forced to work in the spice mines of Kessel. He was later rescued by the rebel crew of the Ghost and agreed to help them in any way he could.
