I just got DOTM Leader Bumblebee today. In my opinion, the backpack is total bulky nonsense. So I removed and re purposed a few pieces from it. It's not much as far as mods go, but hey it works. These are the 2 side guns, and damn if the colors don't work perfect for Leader Starscream. Also I figured out a new way to store the projectiles. I'll let the pics tell the rest.
