Why everyone should get a Shockwave:
(1) It’s Shockwave.
(2) He actually is recognizable in movie format…unlike the entire rest of the Cybertronian cast. Appropriate features and coloration !
(3) He barely ever gets any toys.
(4) See item #1 and multiply exponentially.
I don’t really care if this movie ends up being horrible, too. This all truly doesn’t matter, because nothing shall change the fact that I got a wonderful Shockwave out of the whole deal.
