In G1 the Transformers were shown to carry handheld weapons whenever their needed. In later continuities, it's shown the Transformers can transform their hands into a weapon, like a blaster, sword, etc. Where do they come from? Their not visible in their robot or alt modes. Some Transformers toys show the weapons becoming apart of the vehicle. For example Generations Red Alert's gun becomes an exhaust pipe. Some of the Masterpiece figures have areas where they can simply put their weapons away, in their back (in MP-10'S case) or their legs (Sunstreaker.) This it not shown in any of the animated shows. Any theories?
