Yaddle was portrayed by Phil Eason in Star Wars: Episode I - The Phantom Menace.

This female Jedi Master was a member of the same species as Yoda. She was just 477 years old at the time of the Battle of Naboo, and was a member of the Jedi Council. Some 200 years before the Battle of Naboo, Yaddle was apprenticed to Polvin Kut. They were dispatched to eliminate the threat of the Advozse warlord Tulak on the planet Koba. Polvin Kut was killed in the struggle, and Yaddle was imprisoned by Tulak. Yaddle was buried alive, and only her discipline and attention to the Force kept her alive. She grew strong with the Force, never succombing to anger or hatred, and was eventually freed when seismic activity split Koba's crust. The natives revered her, but were totally unprepared for the appearance of Tulak's son, Kalut. Her control of the Force allowed her to defeat Kalut and finish the work she and Polvin Kut started.

Upon her return to Coruscant, Even Piell proposed her promotion to Jedi Master and appointment to the Jedi Council. One of her foremost critics was, in fact, Yoda himself, who believed that the promotion of a padawan to Jedi Master was againts the Jedi Code. However, Yoda was the lone dissenting vote when her membership to the Council was debated, and her membership was approved. She was known on the Council for her patience, compassion, and wisdom, and was one of the few Jedi entrusted with the knowledge of morichro. She took a delight in the training of the younger students, often overlooking their pranks and hiding sweets in their pockets. One of Yaddle's apprentices was Empatajayos Brand, and she dedicated much of her time on Coruscant to heading up the Librabrian's Assembly.

Seven years after the Battle of Naboo, Yaddle led a mission to the planet Mawan, with Obi-Wan Kenobi and Anakin Skywalker assisting her. Their mission was to negotiate the establishment of a new government there, following a decade of civil war. Unknown to the Jedi, however, was the fact that the most powerful crimelord on Mawan was actually Granta Omega. In the guise of Striker, Omega hoped to lure a member of the Jedi Council to Mawan and kill them, in an effort to impress the Sith Lord he believed to be gathering power in the galaxy. Omega captured Anakin and held him hostage, demanding a meeting with Yaddle. She agreed, and discovered that Omega was planning to unleash an explosive filled with dihexalon gas.

Rather than allow the weapon to be exploded in the city of Naatan, Yaddle drew the weapon to herself and wrapped it in a cocoon with the Force. The weapon imploded, rather then exploded, as Yaddle drew the dihexalon into herself. The deadly toxin took its toll, however, and Yaddle was killed instantly. Her body disappeared as Anakin watched, but the population of Mawan was safe. Unfortunately for Anakin, the young apprentice felt deeply saddened by her death, a death that he felt responsible for and should have prevented.
