Extremely difficult question but what do you think is the greatest TF toy of all time? Please post pics along with your choices. I've always been a Decepticon fan but in my opinion the greatest Transformers toy of all time is *drumroll please*... MP-04 Optimus Prime. This figure was the one responsible for me getting back into TFs. At first I bought the Hasbro version but later sold it and bought the Takara version after they included the trailer with him. I love the size, the fact that he is mostly metal and just the overall look in general.
