I've always been interested in Gnaw. He's was originally introduced as a Decepticon....then in the movie, he was just one of many Sharkticons. Then in the comics, he got his own unique personality back but this time as an "Autobot" or at least an ally, companion of Wheelie...I found this dynamic interesting...although after re-reading the final issues of the Dreamwave G1 comics...it seemed like a possibility that they were setting him up as a mole for the Quintessons....oh well, guess we'll never know.
Modeling-wise, this character intrigued me since well obviously physically he didn't really fit the mold of the usual characters I made. As one person put it, Gnaw was the first FAT Transformer. That in itself enough to interest me. Although I must confess, I purposely shed some of his bulk to make him look less comedic and more imposing...kinda hard though especially with his great big googly eyes....oh well, I tried.
