Transformers: Hearts of Steel
Man, I am so anticipating this one here. Transformers comics are taking a turn into the days of steam powered machinery and whatnot.We have Megatron as a Giant CannonStarscream as a plane of sorts
and the amazing Shockwave
Others include Insecticons, Astro Train, and Bumblebee appearing as a locomotive, which pretty much will say a lot about his existence there.
