It depends on WHO you are targeting.
This line really smells like you are targeting comic book readers/adults more than kids or causal fans.
Like the Justice League cartoon ones (at least where I live) were the main ones leaving the shelves especially John Stewart and cartoon Cyborg. The others including the movies ones-I don't see anyone touching them at Target and Wal-Mart.
Especially around Christmas when they were the only ones left on the shelf with WWE figures.
SOMEONE is buying theses guys for them to keep making them.
Right now he is doing what WWE and others have done-toss out as many versions of whoever is popular. Eventually you are going to hit a brick wall. Folks will tire of it.
Then you will have everyone bypassing Batman for the ONE time Duke Thomas (unmasked) or Star Girl or help us ALL STATIC gets made.
Same issue WWE is having with more folks interest in the figures of who you just fired versus the 200th version of John Cena or Roman or HHH.
Or Star Wars-what Luke figure has NOT been made yet?
I suspect they are probably old school GI Joe sized like the ones Marvel did (or still do).Now these could be fun. I wonder how big they are and if they come with any accessories?
