Favorite Transformer and why?

[Grimlock]

I didn't see a thread for this so here we go. Who is you favorite Transformer and why? If you can't pick just one, pick your top 3.

For me,

Grimlock- I have always loved Dinosaurs so that is what caught my eye at first. In the G1 cartoon, they turned him into a bumbling bafoon, which was fine. It served it's purpose but I don't really like to watch it. The comics on the other hand really are my favorite part of the Transformers universe. They made Grimlock into such a badass and actually gave him some character development. Anyone see the Fall of Cybertron trailer? EPIC! That's all I gotta say. All in all, he is my top pick.

Blitzwing- Mainly because of Transformers:Animated. He was just a nutcase in that show. I loved how he would transform mid flight into a tank and plummet to the ground. And I love purple so he fit in with my tastes.

Razorclaw- This is mostly aesthetic, I really just think he looks cool. The Predacons are really cool though and Predaking looks godly. I really like when the Predacons made their appearance in the IDW book. When I say that spread, it put a big smile on my face.

So, who's yours?
