There is one thing I do not understand about some knock-offs. Example, a lot of the WST Transformers are not official or haven't been made by anybody else. For instant, the WST Devestator, Defensor, and other combiners. So, if these are "originals", how can they be called knock-offs? I have not seen any "official" ones from Hasbro or the makers of the official WST Transformers. So what gives?
