Zinn Toa was a Nautolan Jedi Knight during the years before the Clone Wars.
As a Padawan Zinn witnessed his Master's death when she attempted to save her brother. Seeing her compassion as a weakness, Zinn dedicated himself to the Jedi Order and became known as a recluse. He refused to talk to most other Jedi unless it was regarding a mission and also refused to take up a Padawan of his own. The only Jedi who Zinn had any personal contact with was fellow Nautolan Kit Fisto.
Despite his reputation as a loner Zinn was known to be a skilled duelist, able to fight well alongside his fellow Jedi. However, despite his skill Zinn was overcome during in the Arena on Geonosis and was killed by blaster fire from a Droideka.
