Riyo Chuchi was a female Pantoran politician from the Moon of Pantora which orbited the planet Orto Plutonia. Chuchi served as a senator and represented her people in the Galactic Senate of the Republic during the Clone Wars.
Midway through the War, Chuchi helped negotiate peace between the Talz tribe on the neighboring planet, Orto Plutonia.
Later in the war, she would combat the Trade Federation blockade of Pantora with the help of Jedi Padawan Ahsoka Tano, simultaneously helping the new Pantoran Chairman, Notluwiski Papanoida, locate his daughters, whom the Trade Federation had captured and held ransom.
Chuchi voiced her concerns over the Enhanced Privacy Invasion Bill a short time later and met with numerous other Senators led by Senator Philo of Kinyen. However, terror hit and Cad Bane led several deadly Bounty Hunters into the meeting hall where he planned to blackmail Chancellor Palpatine into releasing Ziro the Hutt for the Senators freedom. Chuchi was shocked at Bane's ruthless shouting and acts against Anakin Skywalker and subsequent assassination of Philo. When an unconscious Skywalker was put with the hostages, Chuchi helped Amidala care for him while cradling his head in her lap. She survived the events shaken but unharmed.
When Ahsoka Tano was put on trial by the Republic for sedition and murder following the Jedi Temple Bombing, Chuchi was one of the senators present as part of the jury.
