Grimlock, Slayer of Titans

During the battle with Shockwave's forces, a freak spacebridge event occurs, taking in many in its wake. Among them, the Dinobot leader known as Grimlock, is sent to another realm. Where giants overrun Earth and humanity is close to extinction. Now Grimlock, and a few other Autobots, must survive in a world where there's no energon and monsters larger than they can handle.
