In the line of bootleg transformers toy series, I find that Nike Transformers was one of the line that have many knock off version in various design and packaging. Here's one of the version that I happen to find when I went for toy hunting locally.
Did you notice the chrome paint on the figure? They even come with a dust cover inside the box. The back of the box shows various toy repaint.
Knock off following Hasbro in repaint? They are as good and bold as Hasbro in term of repainting ideas. They even have a sweet ladies version on Megatron! LOL
Personally I have 2 sets of them in my toy collections. One set I got from a neighborhood shop sometime back while another was a gift from a friend of mine. I got them as I like them in shoe mode.
I am pretty sure some transformers collectors around my region had one if not two of these too.
