I just bought Shock Wave and I got to say, he's so much fun to transform. Sure his alt-mode is lame since he doesn't really turn into anything. But the way everything locks in place and his head is place in some kind of cot-pit for his alt mode. The other cool thing I like is how the wheels of his alt-mode look like rotor generators for his gun arm in bot-mode. The designers of Shock Wwave could of slacked off on his transformation, but you can see they cared. The locking of the pegs and how everything connects really won me over. The ONLY issue I have with him is that he has the dreaded curling iron arms.
