Be really careful with that toy, dude! It unfortunately suffers from brittle plastic syndrome (what's commonly called Gold Plastic Syndrome, but in this case, it's brown plastic).Had I known you were looking for a Transmetal Megatron I would have recommended getting the Takara version - FAR superior quality plastic that won't crumble on you. If you haven't opened this toy yet, maybe consider selling it and buying a Takara one? <shrugs>
