Okay…what I don’t get is that Hasbro isn’t doing anything remotely like this. For once, you clearly have a movie in which a bazillion different versions of the hero costume are canonical – and so far all I’ve seen in the kid range are hardly what you’d call movie replicas. But you can pull them apart, so there’s that.
Also: given how much these things cost (around $300), who is saving all their pennies to buy the more obscure variants? Obviously someone.
The pictures speak for themselves, really. For those wondering, the “Power Pose” series is basically stuck in one position with limited articulation; the other two categories speak for themselves.
