I became very intrested in the idea of Soundwave being in the movie if they ever made a sequal. With those of you who have spoiled yourself with the plot, I can see him comming to earth with one main objective in mind. That said he is a proto type of a military weapon. His alternate mode is a six wheeled large armoued vehicle that mounted on it's back are two sonic cannons. Although there is no physical blast when fired the charge it releases crumples steel like paper. He then transforms into the form you see below. The cannons flip over to form his feet and legs, while the amplifier pods (which transform into his minions like ravage) are mounted up on his shoulders.
I hope you enjoy, and I am open to feedback.
