Arm cannon for GDO Megatron, now with ammo belt! Just picked him up and felt he needed an arm cannon. His long sword was all twisted up from being tied down in the package, so I cut the blade off and kept the barrel section. I plugged it into the big gray cannon from the Constructbots Optimus set, and driller a hole into his forearm: EDIT- I attached his tread to the cannon to make an ammo/energy belt (and, unrelatedly, moved the hip kibble to his backpack): Also fits in tank mode. Not sure I like the blue part on top, but I wanted to keep all the parts on board. Thanks for looking!
When I see the mould, I just see Megatron's "boobs." Very nice though, it has given me an idea for my Blitzwing>Megs custom!
