Alas, the Ninja is a member of the "Hand", which was part of the Henchmen series that were originally slated to come as pack ins to certain Marvel Legends figures. However, the Henchmens concept died in the design room, and they will not be released by Toy Biz. Whether or not Hasbro picks up the slack, I don't know, but as it stands now, the Henchmen series will NOT be released.
Toy Biz was just showing the proto figures as kind of a sneak peek at some stuff that will not get produced.
It's too bad, because I think they had some great potential.
