Thinking of possible customs for the Robot Rebellion group project, I wanted to make a new B.A.T., and eventually thought of making Megatron.
I originally named it Megaton, with the same concept, but ended up deciding to just name it after Megatron, and having him (it) really be an alien overlord coming from the world of Cybertron, to try and take over the world, and taking command of some B.A.T.s himself.
However, I don't think I would be considering Megatron being able to transform into a handgun though. He'll just stay as a robot at all times.
this is my first try on molding a neck ball into a different toyline.
