Almost everything is potential fodder. The Jedi of course are some of the best, and the next up would be the guards.
Figs like Organa, Mon Mothma, etc., are all great fodder too though... I actually wish the preview Wookie would show up again because he's dwindled in my area some. I didn't get many of him on Clearance like I'd like to have done.
He was pretty good fodder. The upcoming 2nd warrior is good too... All great repaint material.
Some of the collection 1 figs are less than stellar as not just figures but fodder too. Obi's, Ani's, Mace... Bleh. That's not the majority though.
Even Clones have repaint potential beyond their army building qualities.
I don't have many figures yet, just a few, but I know I'll be buying extras as time/$ permit... For customs and army building.
