I like the look of Galvatron in IDW's Robots in Disguise series, so tried making one from a Darkmount with a WFC Megatron head (with robot heroes Unicron horn's) and an energon Rodimus gun.
I really like the tank mode (the turret can still rotate) and how the cannon worked out, albeit some part forming is needed i.e plugging the cannon on to the arm.
