Classic Megatron Toy has a really tricky transformation system, simple and cool. I´ve seen many different new toys for Meg since then, changing a gun for a tank (cause of toy safety policies in the USA) or new versions of classic toy, as the masterpiece or some Third parties. All they finally tend to complicate a lot the toy design.
This is my own version of a modern looking Megatron Toy. Since I was a kid, my concept of megatron was an agressive shiny steel robot armed with a huge cannon.
