Don't make me want yet a 3rd version of the Galvatron mold. As of now, I keep Kingdom in cannon mode and use Legacy as robot mode.
I put my Kingdom verison, somewhere, I can't think where, thou I got the legacy verison upon a shelf, and across the room is the selects verison (G1 toy colouring), thou I got the legacy more for the fact the shoulders were built correctly, upon second thought, I just realised where I put Kingdom Galvatron, he in robot mode, stood next to Classics Hot Rod with protector armour, in other words, Rodimus prime, but hiding with Armada OP and Planet X Dinobots nearby, plus the upcoming video game Optimus and BB with pre-earth Jazz nearby, making sure that he behaves himself!
Anyway, it will be intersting to see what this Galvatron will look like when the reveal comes and if he is a new mold or not, about the only improvements I can think of that he needs is (outside of paint):
1. To be slightly taller
2. Taller spike behind his head
3. Covers for the arms in robot mode, don't want to see large holes where his hands swing into
