It's worth noting that some copies (maybe all, not sure) of this version of Megatron have an assembly error in their knees that causes the figure to lean backwards when in bot mode. It's was a simple enough fix, although it does involve removing pins, and directions can be found online pretty easily. Once it's done he doesn't fall over backwards quite as often.
Now I have a Miner Megatron, I feel I need a Senate Leader Thatcher-tron for him to face off against.
