I wish I could buy these in an animated style:
Senator Aconda Far (Rodia)
Senator Ask Aak (Gran)
Ithorian Senator (Hammerhead)
Senator Orm Free Ta (Twi'lek)
Senator Mon Mothma (the future leader of the Rebel Alliance)
The Fat Niemoidian (from that episode on the plains with Aayla Secura)
WagTwo (the squirrel like creature that rolled in a ball)
Little Fosh mercenary
little droid mercenary
Peppi - female Gungan herder
Mad Scientist Doctor who created the virus on Naboo
Padme Amidala in her Environmental Suit
Jar Jar Binks in his Environmental Suit (this is funny)
Padme Amidala as a Senator (same outfit she wore in her apartment in AOTC)
Bail Organa as a Senator (but with blaster and holster)
Chancellor Palpatine (red or dark blue outfit) - he's the leader of the Republic!
Ziro the Hutt
The second and third lists are more likely because they are more recognizeable characters, but two of them are from very specific episodes - though so were Snobi-Wan and Snow-akin.
In the first list there are a few episode specific characters from Season 1, however, they have made very episode specific figures before (the Talz and the new bounty hunters from season 2, for example).
