Super Freak
I have been thinking picking up another curio so i can make a villian display (actually my girlfriend suggested it). It would be Red Skull, TWS Winter Solider, Whiplash MK2, Mandarin, A1 Loki with Chitauri, Ultron Mk1 and Ultron Prime. I like the new crossbones figure so he could join them.
That would be a good looking villain shelf.
I actually don't have a separate villain shelf per se; I have most of my figures consolidated by film, villains included. I'm contemplating picking up a Crossbones as well, as I really like the outfit and I like the way the figure apparently turned out. I want to get an IW Thanos also (presuming he'll include the gauntlet), but provided the price is right.
On the DC side, the only villain I currently have is MoS General Zod.
