History
The Freedom Fighters, also known as The Rebels,[2] were a group of revolutionaries comprised of Earth Kingdom refugee teenagers and children under the leadership of Jet, who aimed to rid the world of firebenders, even if it meant killing innocent people.[3] They were all skilled woodsmen who communicated with bird calls to avoid detection and planned their attacks from a secret treetop hideout. Ever since the Fire Nation took over the nearby village of Gaipan, the Freedom Fighters had been cutting off Fire Nation supply lines and using all available means to sabotage their occupation. They were all wanted by the Fire Nation.
