Well, 2D would suck, just because of the clean up on the arm and leg. I meant more 3D. With the proportions being as they are, it would really allow for some exaggerated movements, especially some more animalistic/ king kong style actions. Then, with his mechanical parts, you would get to play with the weight variations, as well as varying their movements against his organic limbs. And then since he has a slight cowboy vibe, you could play him the strong, silent, subtle type as well. Lots of variety. Of course, I've been animating beasts and robots for the last year on the hulk, so this is right in the ball field of what I've gotten used to lately.
