Grimlock

Grimlock (グリムロック, Gurimurokku) is a wild card among the Autobots. Huge and powerful, he is also hot-tempered, impatient and reckless with a rather rough n' tough attitude. He views Optimus Prime as a weak leader, too afraid to make the tough calls and act on instinct. As such, Grimlock is more than ready to disobey orders if he thinks the ends will justify the means. His one obvious redeeming feature is his attachment to his team. As leader of the Lightning Strike Coalition Force during the early days of the war on Cybertron, he commanded a group of similar minded individuals he would do anything for. Together, they handled the jobs the Autobots didn't have the stomach for.

Shockwave's experiments not only granted Grimlock a new alternate form, but also increased his power tenfold. Unfortunately this came at the more violent and aggression he became. While he is average intelligent, far from stupid, Shockwave's experiments have made it more difficult for the former field commander to think rationally and made his already prominent rage issues all the more severe. Fortunately his team, similarly reborn as the Dinobots, became more tight-knit than ever. Together, they helped him overcome his disgust at what Shockwave had done to him, and before long Grimlock had embraced the advantages of his newfound power.

One of the most powerful warriors alive, his general approach to a problem is to smash it first, worry about the specifics later. This attitudes extends to his Autobot companions, who are expected to meet Grimlock's standard of strength. That said, the Autobots have a lot less to fear from this behemoth than the Decepticons.

Grimlock more than lives up to the reputation of his Tyrannosaurus Rex mode. Ill-tempered, powerful, and always ready for a fight, he loves to throw his weight around. He likes the way the ground shakes as he stomps around, and the way people scatter when he roars. He's happiest on Dinobot Island, where he can stomp and roar to his Spark's content, shattering trees with his tail, and breathing jets of flame into the sky. Every once in a while, though, he prefers to find the biggest, most powerful Decepticon he can, and smash its chassis to pieces.

He has battled countless enemies across the universe, never concerning himself with trophies, only victories. There was a time when the rage that boils inside Grimlock would have driven him straight to the ranks of the Decepticons. But he's smart enough to recognize a bully when he sees one - and Grimlock doesn't like bullies. He has proven difficult to capture and nearly impossible to defeat. When an enemy does manage to get the best of him, it's never for long. It's this that fuels his dedication to fight against the Decepticons. Un-caged and unleashed, Grimlock is concerned with only one thing - vengeance against those who would try to control him.

Personality
Grimlock is an impatient and willful Autobot. As he's more than willing to disobey any direct order if he thinks that the ends will justify his means. He gets anger issues if anyone dares to tick him off, they're scrap. Despite that, he is loyal to the Autobot cause and is willing to risk his life to rescue his comrades from capture.

During Shockwave's experimentation on him, Grimlock gained a new "Alt Mode" making him more aggressive than ever. Grimlock's impaired speech pattern hide's a surprisingly intelligent mind.

Grimlock is also shown to be more mature and a bit smarter, and he has better speech patterns and is less arrogant. However, he is still shown to be easily angered on some occasions.

Weapons and Abilities
Physically, Grimlock is one of the strongest Cybertronians alive, he has accomplished amazing feats using his berserk, monstrous strength, he has pushed down towers with ease, break through steel walls, single-handedly took down an army of Decepticons, was able to go one-on-one with Megatron (once), smash boulders with his bare hands. There are some rumors that Grimlock's strength is limitless, he might even overpower Unicron, his rage also fuels him with might, the angrier he becomes, the stronger he gets. He is also equipped with an Flame Energy Swords, whose blade can ignite into a sword of flames, which can also be shot from his sword.

In his Beast Mode, Grimlock's strength is compareable with in Earth T-Rex and somewhat stronger than his Cybertronian Form, his jaws are so powerful, he can bite through virtually anything (unknown if he can actually bite through the apex armor), Grimlock can also bite Decepticons in half (though it noted Cybertronians are no cannibals, like Chompazoids eating only "cruchy materials to power themselves up). His T-Rex mode also has the ability to breath fire, the superheated flames that Grimlock shoots/breathes is so hot, it can burn buildings from miles away, these fires can also burn Decepticons down.

His lack of fear makes him a dangerous foe, he loves to fight, often he starts one, he isn't afraid to fight either Bruticus or Devastator. But his berserk-like anger makes him too dangerous to other Autobots as well, (as stated by some Autobots that "In the battlefield, better fear Grimlock than the hoard of Decepticons around you").
