Cutest Widdle Toothy Death Machine Ever!
I may have been known to use that phrase IRL when I first saw the TR Gnaw figure.
This one of my Sharkticons is a custom Headmaster Sharkticon. I blatantly stole the idea from was inspired by someone in the Transformers Customs group on Facebook, and the other person who came up with the names.
I, however, used the Titan Master from the Laser Prime from the Chaos on Velocitron box set. (He was about the right colors. The teal in particular looked like a good match.) I separated the two halves of the Gnaw head, and used Sculpy to attach it to the Titan Master's back. It's not a perfect fit, but it works.
