Hello
hii admin ..hru …I bought all 20 figures on May 1st from a few stores around town… with the majority of the figures coming from Target. So today I went out to TRU to take advantage of the buy 4 get 1 free sale and had full intentions of returning the worst of each figure to Target.
New member here. I know, old thread, but this post is twofold. One, I recently began collecting this line maybe 3 months ago and am taken aback at all these variations. It’s got my head spinning. Second, I need to make a single post as you all know before I can start making threads. Next post: Introduction! 
That will never happen. That show and continuity is dead, and BanDai has no license (or much of an American market presence) anymore.
