Disillusioned by the oppressive regime that the RDA has forced onto the indigenous Na'vi people, Trudy Chacón plays a crucial role near the end of the film when she rescues Jake Sully, Norm Spellman, and Grace Augustine from their imprisonment in Hell's Gate. Trudy also used her Samson 16 to lift one of the remaining link containers (a device that allows humans to link to their avatars) away from Site 26 and into the ancestral Na'vi site known as the Tree of Souls.

Painting her ship with Na'vi warpaint and wearing that same warpaint across her eyes, Trudy Chacón participated in the Na'vi's final stand against the RDA, piloting her Samson 16 in aerial combat during the battle for the Tree of Souls. When the tyrannical Colonel Quaritch (Stephen Lang) brought his Dragon Gunship into the fray and set his sights on Jake, Trudy fired on the Dragon in a desperate effort to save Jake's life. She ended up paying for this act of bravery with her life, as her Samson 16 simply couldn't match the Dragon, and crashed to the jungle floor in a fiery explosion.

Despite only appearing briefly throughout the first "Avatar film, Trudy Chacón played a crucial role in Jake Sully's rebellion against the RDA, and is well worth remembering for her brave sacrifice in the ending of "Avatar."
