A lot of people seem displeased with MP Megatron. On the other hand I am very happy with how Takara made him. He is lite enough for a comfortable Transformation and I can see how Die cast on his upper body would have seriously hampered his stability so I support the use of plastic.

They could have added some Die Cast to the legs just like the upgrades in the Unofficial kit but I am not fussed about it.

It has been transformed at least a dozen times and never had any issues with him, he is very durable and although some parts feel a bit flimsy, it is strong enough to manipulate without needing to be overly careful.

If you just want the feel of more weight to the figure then I suggest the upgrade kit which comes with the extension and metal leg plates.
