Actually, it's pretty hard to choose, since a lot of them are great, but I'm going to have to go for this clunky bugger: http://brickset.com/detail/?Set=6856-1
It's basically a box with wings, two satellite dishes and an antenna stuck on it, with a nuclear reactor pod above the pilot's seat.
Whatever the specific name, it's probably just the apple-ish trans green he used before. Also, you've got a good point Aanchir, but seeing how it lines up with the rest of the torso, I think it's probably not connected via the back.
It's pretty weird, how up-to-date it is.
EDIT: Here's the whole episode:

Pretty awesome, the Leviathan's release was a nice touch and the eye-tentacle is rather funny.
Also, the shield used in Rocka and Bulk has it's first HF release. I might use the brown from this wave to make a dog-like character, which I have been wanting to do since I first saw Savage Planet Bulk's helmet.
I agree. However, in some way, he does kinda fit with the image I have of him: lanky, but with more powerful "muscles" (pistons). Also, I quite like it when sets have similar builds, as it allows for more interchangeability of parts, without the result having a completely different style.
