So far the only place I've seen these larger figures is at Target. They must have thought the line was going to be really popular because they ordered a metric sh*t ton of them. Sadly the figures sat undisturbed on the shelf for many months, which is really too bad, because they're quite cool.
Why the lack of consumer interest? Possibly because no one knows what the hell they are. Kids are like lemmings; they like to follow the herd. They want toys based on Pokemon and Star Wars and other recognizable properties. They don't want a room full of toys from some card game that Aunt Edna assumes is cool and that none of their friends play, lest they become the laughingstock of the playground.
Another likely reason these figures were shunned: the cost. Each of these figures were priced at a whopping $20 smackers. That's just way too much for an action figure, even one of this size. Target finally came to their senses and marked them down to a much more reasonable $4.78. There's no way in hell I would have ever paid $20 each for these figures, but $4.78 is a steal, so I bought them.
Note those large spikes on each shoulder. Bad design. The first time he raises his arm those two spikes are going to impale the sides of his head.
