One Jedi Master was Plo Koon, an imposing alien whose face was concealed behind a forked facemask. His well-muscled humanoid form filled out the traditional Jedi robes. Koon was present on the Council when Jedi Master Qui-Gon Jinn presented Anakin Skywalker as a prospective Jedi candidate. He also served the Council a decade later when the Jedi faced one of their greatest conflicts: the Clone Wars. Plo Koon was present at the first battle site of the Clone Wars, fighting against Geonosians and battle droid forces in the cauldron of the Geonosian execution arena. Koon served valiantly as a general in the war on many battlefronts in the years that followed.
