Flynn Kybo served in the Clone Wars as both a Jedi Commander and a Padawan. He was a male Human.
T'chooka D'oon, Kybo's Master, met his death at the hands of General Grievous during a mission to Vandos to save Ambassador Quiyyen. Following this event, Kybo assembled a group of Jedi with the goal of hunting down and eliminating Grievous, an action that was not sanctioned by the Jedi Council.
Ultimately, they located Grievous on Belsus, a moon located within the Anoat system, where he held a number of young Padawans as hostages. While Codi Ty worked to get the Padawans to safety, Kybo and B'dard Tone engaged Grievous in combat, their lightsabers clashing. Tone was killed in the fight, and Kybo, in a last-ditch effort, severed a gas pipe, releasing its contents into the magma below, intending to take his own life and Grievous's with it. While he did succeed in killing himself, Grievous managed to survive the explosion.
