Grimlock is the king if the dinobots and one of the strongest autobots. He is a cool fire breathing Tyrannosaurs Rex and is basically the autobot Starscream and wants to take over the autobots but is still pretty loyal to Optimus prime unlike Starscream is to megatron. He also maybe the dumbest autobot
“Me Grimlock want deception metal”
