Mon Mothma is an NPC, an honest Senator who later became part of the Rebellion against the rest of the Senate, which had grown corrupt with power. She speaks with a heavy Space Valley Girl accent.
Revelation of the Sith Edit
Mothma, along with her fellow Senators Bail Organa and Giddean Danu met with Senator Padme Amidala in her office to discuss the Federation's invasion of Naboo. Padme asked what she could do about it, now that she was pregnant. They suggested she lead the debate in the Senate. Padme wanted to know what was being done about stopping the invasion. She was told that the Senate had tried to send Obi-Wan and Anakin after the invasion fleet, but Padme interrupted that that was unfair because she wished she could take on the invasion fleet too. Finally she decided that she and the other Senators should start a rebellion in the Senate about...something.
C-3PO and R2-D2 were attended a meeting Padme was having with her fellow Senators, including Bail Organa, Mon Mothma, Chi Eekway Papanoida, and Bana Breemu. Padme suggested they overthrow the Senate, but her fellow Senators were all weak-willed and timid except for Bail Organa. Mon Mothma said that she thought that would be totally over the top. Besides, she'd just had her nails done.
