Since 2002, the various Marvel Legends toy lines have been steadily pumping out our favorite heroes and villains with cool accessories and even cooler build-a-figure characters. However, for every Wolverine (and there have been a lot of them), there's been at least one figure that was left on the sculpting room floor.

Whatever the reason, there have been plenty of Legends that never made it past the prototype stage, leaving fans wondering what happened. Sometimes a figure gets abandoned due to budgetary reasons, and other times, there's just not enough interest from retail or fans. The worst instances are those times when there's no real explanation at all, and a potentially great figure is left collecting dust in the darkness.

Such is the case with many of the culprits on this list. Many of these planned figures were really great ideas, but for some reason, either Hasbro or Toy Biz just didn't pull the trigger. It probably wouldn't have been so bad if so many of these characters hadn't been shown in person or announced, but it's the knowledge that somewhere out there a version of Madrox or Cyclops exists that you will never own that stings the collector inside us all.

Despite all the evidence to the contrary, even a glimmer of hope that a figure will see release is often enough for collectors. If we're loud enough, maybe some of these Most Wanted Unreleased Marvel Legends will find a way onto our shelves.
