The improvement over the original Stormer is pretty intense. The original looked good, except for the weapon/hand/arm piece, but had woefully limited movement of the limbs. Flexibility was downright terrible. Stormer 2.0 has as much playability as any of the new heroes, meaning a lot, and he maintains a dignified, strong appearance. His weapon isn't spectacular, sharing the main piece with Nex, Furno, and Evo, but he does include a thin translucent ribbed silicone hose with a blue streak through it that makes me want to buy up a couple dozen of them. It's just a beautiful piece.
All in all, Stormer 2.0 is about as good as the first series of 2011 sets get.
