Movieverse Sharkticon

There are places I'm pretty sure the Bay Movieverse will not go- Dinobots, Sharkticons, Quentisons, etc.
But when Hasbro comes out with movieverse figures of character who weren't in the movies, they seem to get the colors more correct that they do in the films.
Soooo, I made this movieverse Sharkticon, Gnaw; a more realistic version of the original.

Gnaw's Bios:
Sharkticons are terrifying creatures.
First seen by a few captive Autobots on a distant alien planet called Quentessa, they were used to torture and kill any life forms the planet's inhabitants found.
Sharkticons usually travel in packs and the packs are usually grouped. Normally, if you are unlucky enough to run into one, you also meet over 100 more.
Gnaw is different though. He thinks just a tiny bit more that his savage kin, and holds a grudge against the Dinobot leader, Grimlock, for crushing many of his closest friends. It is for this reason that he joined Galvatron as a Decepticon.
Galvatron does not trust Gnaw, but then, he trusts very few of his minions.
Sharkticons transform to a more humanoid form for using tools and thinking more clearly, but they are not from Cybertron. They are called Sharkticons because of the sharp teeth and fins, yet they are actually more like robotic lobsters or insects. They must eat to survive. Anything living will do for sustaining the fleshy organics hidden within their resilient metal bodies.
They can survive almost anything, slowly regenerating even lost limbs over time.
The only way to kill a Sharkticon is to somehow destroy the soft organic life inside their torso.

I put alternator arms, scout bot legs, an ROTF Arcee motorcycle front section, a BW dragon Megatron tail, 2 toothpicks, a FAB Blackout head modded onto a ball joint, and some sculpt and custom cut parts onto a Mutant Spawn figure to make this.
Oh and then I painted him.
