Like most six year olds, Optimus Prime was my favorite Transformer. But Grimlock was my favorite toy. The Dinobot leader was at the center of so many of my kitchen table battles that he actually shattered after one nasty fight versus Abominus.
So seeing the first Transformers: Fall of Cybertron teaser, which stars a monstrous-looking Grimlock, is a particularly effective piece of marketing.
Transformers: Fall of Cybertron is in development at High Moon Studios and is currently on track for a 2012 release.
