I have it, and I don't know if this is a FULL list, but these guys are in it.
Anakin Skywalker EP2
Obi-Wan Kenobi EP2
General Echuu Shen Jon (they made the campaign largely based around his clone wars experiences)
I'm not sure if some of those came with the original, since I bought the double pack. But I know many of them made their first appearances in EP2. Hope that helps.
