Give some extra parts for the chest.(not done yet) Balljoint for the head, and changeable Rotf version head. Give some parts for the shoulders, new speakers, give a joint for the new Laserbeak from Studio Series, and new joints for Rotf deluxe Soundwave's blades. Built a new gun from spares parts. I will give some extra parts for his legs, and try to do something with his backpack. What do you think guys?
