The Force runs strongly in Plo Koon's family; he was a descendent of a long line of Jedi. He shared a long history with fellow Jedi Master Qui-Gon Jinn, and the two have fought beside each other in battle. Koon had hoped to see his friend join the Jedi Council, but Jinn's maverick views kept him from ascending to that position.
Plo Koon was a Kel Dor from the planet Dorin. His physiology was such that he wore protective goggles and his face-concealing antiox mask whenever in oxygen-rich environments. As a Dorin, Koon naturally possessed highly developed extrasensory organs that supplement his already formidable Jedi attributes.
Koon was more martial a Jedi than most. Kel Dor natives have a reputation for seeing moral issues in black and white, with clear distinctions between right and wrong. As such, Koon often took decisive action with little contemplation. This initiative served him well during the Stark Hyperspace Wars, when he took up the Republic banner after a great Jedi Master was killed. Koon rallied the disheartened troops to an unlikely and miraculous victory.
