I have a Classics/Universe Megatron (Voyager size)? that I am repainting to G1 colors, it's coming along nicely. My son has the Classics Prime and one thing I've never liked about this is the arm shields (whatever you call them) that form the sides of his cab. I don't particularly want to kitbash my son's toy and I really don't feel like getting my own just to bash, wonder if there's alternative Prime's in this same size to use as a counter to my Megatron? I am willing to bash a new Prime, just want to do something new.
