The big guy himself, the king! Grimlock, leader of the Dinobots, is coming to the big screen after Michael Bay himself swearing off ever using such a silly concept as Dinobots in his films. Not only that, we are getting a BIG BIG BIG version of Grimlock, so big that Optimus Prime can ride upon his neck. This is bound to be an image that is burned into the lore of Transformers forever.
