Transformers War For Cybertron (Game first appearence)

Rival Joseph Turok
Grimlock was an autobot from the Transformers franchise. Once, he is from the Generation 1 or G1 Transformers which features Grimlock as a toy, in the Transformers comic, or several cartoon series. He is a DLC character that can be purchased for $ 0.99.



In the original G1, many Autobots has wondered, why Grimlock chooses the Autobot side. He is dim-witted and sluggish and also prefers power and strength over wisdom and compassion, which matches the Decepticons. If he encountered a problem with one of the Autobots, the only way Grimlock may know is tearing it apart with his bare hands or slicing and dicing with his Energo-sword. Neverthless, Grimlock was a good strength asset for the Autobots. Besides, can the Decepticons face a huge, hulking and brutish Autobot that has a form of a massive T-Rex?

  • Transformers Fall Of Cybertron
  • Transformers Rise Of The Dark Spark



Grimlock was at Cybertron, at least the remainings of it. Grimlock is exiled to Cybertron's remainings along with his Dinobots due to the fact they didn't agree to Optimus Prime on Earth to protect the humans due to the fact the humans are now hating them and considering them as a threat. One day, Grimlock receives a message from Optimus Prime, that says there is a source of power, not Energon or anything else the Autobots or Decepticons know, but much more powerful. Optimus is on the way to gain the power, then the message was cut. Grimlock, hearing the message, thoughts that Optimus was now power hungry. So now, Grimlock travels back to Earth to gain this power source, no matter who stands in his way, he will destroy anyone, especially humans, who he had heard that there are a lot of humans chasing for the power source.


Name : Joseph Turok

Reason : Grimlock lands on the rival arena, sensing a lot of power in the arena. Grimlock thinks that the arena was composed of an energy or a material resembling Energon. Grimlock then thinks that the arena itself was a "battery" station for him. Then, Joseph Turok came to him, admiring his size, Joseph "mocks" Grimlock that he was too big for the power. Grimlock, hearing this, thinks that Joseph was also chasing for the power. Then, Grimlock warns Joseph to stay away from the power. Then, Joseph doesn't listen but he ignores Grimlock, saying that the power belongs to him. Hearing this, Grimlock was enraged. He says that Joseph was a coward that he ignores Grimlock. Then, Joseph mocks Grimlock that he is an idiot. Grimlock then became really enraged and transforms to his T-Rex alternate form. Looking at the transformation, Joseph became shocked and readies himself for battle. Then, in his T-Rex form, Grimlock says that he will die in a matter of second.

Connection : Both Joseph Turok and Grimlock was connected to Dinosaurs. Both are also associated with "alien Dinosaurs". While Joseph encounters "alien Dinosaurs", Grimlock WAS an "alien Dinosaur" due to the fact he is a Cybertronian. Both of these character's technological characteristics also a vice versa. While Grimlock uses high tech, or just futuristic weapon, the weapons Grimlock use was used before the humans existed in Earth. While Joseph uses human weapons that is maybe considered "old" to Grimlock in the future. So basically, both use futuristic weapons but in a different time. Again about the dinosaurs connection. While Grimlock's alternate form was a T-Rex and his group is called Dinobots, which is clearly associated with Dinosaurs, Turok has faced some Dinosaurs, giving him an experience in "Dino-killing".  Turok may also have encountered an enemy that resembles Grimlock, which is Mama Scarface, which is a T-Rex, which (again) is Grimlock's alternate form.


  • Grimlock : "This place..... Me Grimlock thinks it is made of Energon! This might be a recharging place!"
  • Turok : "(Came to Grimlock) Oh my.... what a big size you have there, brother! Even I feel something bad about you, eh?"
  • Grimlock : "Me Grimlock thinks about you puny man, are you wanting the power? If you want, stay back and away."
  • Turok : "What did you just say? That power belongs to me, freak."
  • Grimlock : "Bah! Me Grimlock says you are one coward, fool!"
  • Turok : "Dude, calm down, you're too idiotic for this one."
  • Grimlock : "Grrr....... (Roars then transforms to his T-Rex form)"
  • Turok : "Oh fuzzy furball. (Prepares for battle)"
  • Grimlock : "(In his T-Rex form) You will die in no time!"


After defeating Polygon Man, Grimlock gained the power and suddenly, the boss battle arena "teleports" Grimlock to Cybertron. Back to Cybertron, his Dinobots met up with Grimlock, feeling a large amount of power. Grimlock says that he didn't know what shall he use this power for. Finally, Grimlock got an idea : rebuild back Cybertron. The Dinobots agreed to Grimlock and then suddenly, Grimlock floats with his hands spreaded, and then, the old Cybertonian grounds goes up, and there, Grimlock rebuilds Cybertron, the Utopia for the Transformers.


Grimlock was a slow lumbering character. But his movelist did packs a real punch, punishing everyone who came to him, both fast and bruiser characters that attacked him, expect a little AP to gain. Grimlock crushing everyone to gain a lot of AP? That can happen very quickly. All of his moves are chainable and devastating. What else can be expected from this juggernaut? But consult this : He is pretty large, he's an easy target. But he has no problem attacking small characters.
