Stopped by a local comic shop over the weekend and they had a few of these figures out. I haven't bought any online because they don't seem to be selling cases for some reason. Anyway, I saw Batman, Catwoman, Joker, Two-Face, Mr. Freeze and Creeper. Ended up just getting Batman for now since the store wanted $25 a pop and a lot of the villains are $20 or less on Amazon.
The Batman is pretty cool though! The cape is made of a soft rubber material, and doesn't hinder the articulation at all. There are a ton of hidden accessories too, like extra hands, Batarangs, grapling hooks, even an extra "blowing in the wind" cape! Highly impressed with this line so far, and I can't wait to get my hands on the other figures.
