Sunchoo was a female Wookiee living on Kashyyyk during the Clone Wars. Stolen from her village by the bounty hunter Crovan Dane, she was sold into a life of slavery in the service of a Neimoidian Trade Federation official, Gama Bankor. In 21 BBY, she was about to be taken off the planet by the Neimoidian when she was freed by Jedi Master Bant Eerin's Padawan and the Jedi youngling Jaylen Kos. She proceeded to aid them in their search for Dane.
