Starting off, my only issue with TLK voyager Megatron was that he had no battle mask, even though the pieces were there. That would not do! So, with the help of a broken DOTM Bumblebee, I got a decent looking battle mask. It also can open back up At first, I was going to just put channels in the side of his head so the mask bits could alide around...that didn't end so well. So, I ended up using DOTM Bumblebee's thigh joints (the ones that move his car bits around) and cut those up. I also removed the clips on the mask pieces and glued those onto a platform from the Bumblebee joint. Also had to put in pins, since the glue wouldn't hold. After that, it was just cutting a big square in the side of his head and gluing the pieces in. Also needed to bend/shave down the mask pieces a bit so they fit the shape of of his head better Could use a bit of cleaning up, but that's pretty much it. Action pose!
