I bought a lot of G.I. Joes on eBay, and this thing was in the box. (I'm not sure the guy even knew it transformed ). It is probably a knockoff, as I can't find a symbol on it, and it doesn't have a Hasbro, Takara, or Tomy copyright. It says "China Patented. Made in China" on the bottom. As you can see in one of the pictures it has a chompy mouth on the front of it's chest, which forms the front of the tank. It also had a place for batteries on the tank barrel, but I can't imagine what that would be for. Please tell me if you can't see the pictures; this is the first time I've posted a picture on here .
