Grimlock is the leader of the ancient Dinobots. He is a fierce warrior.
Grimlock is Leader of the Dinobots, he and the rest of his fellow warriors once navigated the universe in their ship, the Knights Temenos. However, when it was hijacked by the bounty hunter Lockdown they became prisoners in their own ship.
Centuries later, when Optimus Prime needs help in Hong Kong he freed the Dinobots. To gain their trust, Prime challenged Grimlock to a match and won, taking advantage of the size of the enemy. Optimus, now saddled on Grimlock, rushes into battle with the rest of the Dinobots along with Drift and Crosshairs. Together they destroyed many enemies, together with the Autobots they then defended the bridge so the Decepticons couldn't reach the Seed.
When Lockdown returned, Grimlock suffered from the power of the magnet on the bottom of Lockdown's ship as he and the other transformers couldn't escape its magnetic pull. After the battle was over, Grimlock was released along with the other Dinobots.
