Transformers Movie 3's mech tech is pretty bad design, but that gave me an idea: How about combine movie 1 scorpion to movie 2 Leader Megatron? That can fix his little left arm issue ( Actually I think it's his feature. ) So here we go: 1) took out the hexagonal part at the back of scorpion. As shown in the picture 2) ready to combine. (You don't need to worry about the hexagonal part, it can be inserted into one of the holes on scorpion.) 3) Fits prefectly, from now on, movie 1 scorpion can be movie 2 Leader Megatron's left mech tech arm. Now see the results: 1) StarScream: I will never dare to betray u again, master 2) One shall stand, one shall fall!
