Hmmm. Let's see what I can think of for a decent ROTJ 8 figure wave.
-Luke Skywalker - Death Star 2 duel
-Emporer Palpatine - new sculpt, SA, softgoods, cane, force lightning
-AT-ST Driver - SA, removable helmet
-Nien Nunb - SA, removable cap
-Paploo & Wicket 2-pack
-Wooof - Vintage Klaatu
-Geezum - Jabba's Palace Snivian
-Weequay - Skiff Master
