I was looking forward to finding a leader class Megatron today but none of the stores had him. I wanted a closer look at him to see of his head can be pulled off in vehicle mode. So I have to ask here. For anybody that has him, can his head be pulled off? Is it on a ball joint or is there a screw that you can take out? I really don't like how his head is visible in vehicle mode & I'm hoping it can be removed.
