YES!!! I remember Rattrap! He was off of Beast Wars! Anyways, only real complaint is that you should have made the top of his with a pink stud to signify his brain from the old TV series.
It’s very good. My only complaints are the color placement and proportions; the rat head is too small and his shoulders are too broad (at least for Rattrap).
This is one of the best mocs I have ever seen. However, that is filled with immeasurable amounts of bias. I love Beast Wars. Its what got me into Transformers in the first place. I watched it all the time when I was little. I also have the complete series on DVD. Not to mention that Rattrap is one of my favorite characters. You should do more Beast Wars.
