In robot mode, Grimlock wields an energo-sword, whose blade is sheathed in crackling energon and can slice a 2 foot (0.6096 m) concrete wall in one slash.

He is almost invulnerable in his Tyrannosaurus Rex mode as shown with his battle with Megatron due to Megatron's primary weapon, his arm-mounted fusion cannon having little or no effect on Grimlock.

Reception

Grimlock was one of the favorite Autobots of IGN.

Grimlock was voted the 6th top Transformer who was considered to be "badass" in the comics by Topless Robots.

According to X-Entertainment Grimlock was the 2nd top Transformers figure of all time.

. The Ark's computer detected his presence on the planet, and its scans of the Savage Land led it to believe that dinosaurs were the dominant life form. Thus, it reconstructed Grimlock and his troops into dinosaur forms, in order to battle Shockwave. Unfortunately, he slyly outmaneuvered them and managed to pick them off at a distance with his superior fire power; knocking them into a tar pit one by one. With their final strike the battle ended in a stalemate as the Dinobots made him fall in the pit along with them, buried under a rock slide for several million years.

In 1984, when Shockwave was accidentally reactivated by an Autobot probe and took command of the Decepticons from Megatron, Autobot medic Ratchet entered into an uneasy alliance with the deposed Decepticon leader, agreeing to recover the Dinobots so that they might defeat Shockwave again. Ratchet

 pulled a double-cross, however, and had the Dinobots attack Megatron instead, resulting in a battle that ended with Megatron's disappearance.

Grimlock steadily grew more and more displeased with Optimus Prime's leadership, and eventually broke his Dinobots away from the main Autobot faction. After a prolonged period living in self-imposed exile, the news of Optimus Prime's death brought Grimlock back to the Autobots. After proving his worth by defeating the Decepticon Trypticon

, Grimlock was elected leader of the Autobots.

It soon proved that absolute power corrupts absolutely. Grimlock developed into a tyrannical ruler who led the Autobots with an iron fist. His policy towards Earth and its inhabitants were vastly different from Optimus Prime's – instead of viewing them as objects of protection, Grimlock expressed a disdain for humanity, viewing them as an inferior species unworthy of their protection. Under Grimlock’s leadership, the Ark was repaired and made space-worthy again.

In issue #32, titled "Used Autobots", Wheeljack completed work on his Geothermal Generator, which used the heat from the volcano the Ark had crashed in to generate energon cubes. Although Wheeljack thought this would impress Grimlock by reducing their dependence on human help, Grimlock seemed to think the Autobots should just take what they need from the humans.

 and failed to establish an allegiance with his group. This proved to be the last straw for the Autobots under Grimlock's command, who collectively conspired to overthrow him, arranging for Blaster to challenge Grimlock for leadership. During their battle on the moon, the Decepticons took advantage of this weakness in the Autobot ranks and interrupted the duel with an all-out assault. With all Autobots now under attack from their mortal enemies, Grimlock and Blaster put their differences aside and fought alongside each other against the Decepticon horde. Subsequently, Fortress Maximus orchestrated the recreation of Optimus Prime as a Powermaster, and Grimlock stepped down as leader.

. Ratchet shortly after was lost in a transport incident while taking out Megatron, and was thus unable to continue his work restoring other Autobots in stasis lock (Ratchet later returned, physically merged with Megatron). Grimlock swore to one day find a way to revive his Dinobots.

Under the leadership of Powermaster Optimus Prime, Grimlock proved to be a loyal and powerful Autobot, daring even to battle the Matrix-powered Decepticon Thunderwing during the Matrix Quest. However, he was still obsessed with quickly reviving the Dinobots, a goal which put him at odds with Optimus Prime, who advocated patience in the search for a way to rebuild the fallen Autobots. Grimlock finally lost patience, stole the bodies of the Dinobots and a shuttle from the Ark, and piloted it to the planet Hydrus Four, where scientists had developed a new fuel called nucleon

. It was more powerful than energon and capable of bringing dead Transformers back to life, but it was unstable and could have unforeseen consequences. Grimlock was unwilling to subject his Dinobots to anything he would not go through himself, and thus decided to test the fuel on himself first. When no ill effects were apparent, he used it to revive the Dinobots, and brought enough back to revive the remaining fallen Autobots.

The Dinobots returned to Cybertron with the nucleon, and arrived in time for the battle with Unicron

. Their arrival, and their reviving the fallen Autobots with Nucleon, was an important part of Transformer victory that day, but Optimus Prime once again lost his life, sacrificing himself to destroy Unicron, and once again naming Grimlock as his successor with his dying breath.

Before Grimlock could celebrate his new position, however, the Nucleon's effect on Transformers became apparent. Grimlock began to experience brief bursts of immobility, his joints locking, which reached a peak when he became completely paralyzed in Cybertron's wastelands while he and the Dinobots were under attack by monstrous creatures from beneath Cybertron's surface. Realizing that Grimlock had become trapped in a "chrysalis" stage, Prime's Powermaster partner, Hi-Q, tapped into and accelerated the process, completing Grimlock's evolution into a more powerful "Actionmaster" – but the enhanced power came with a price: Grimlock was now no longer able to transform into dinosaur mode.

At that point, Cybertron was believed to be dying as a result of the battle with Unicron, and the Autobots and Decepticons were co-operating to evacuate. However, the Decepticons had a hidden motive: to escape, and leave the Autobots marooned on the dying planet. Grimlock and the Dinobots were the only ones among the Autobots who saw through the Decepticons' false pretense of peaceful co-existence and suspected the plan of mass betrayal. When the Decepticons sabotaged the Autobots' ships and fled the planet, Grimlock saved the Autobots. He revealed that he had captured Decepticon ships after a strike against them before the voyage to Earth, and had hidden them away. Thanks to those ships, the Autobots were able to flee Cybertron and follow the Decepticons to the planet Klo for a final showdown. Unfortunately Decepticon leader Bludgeon

Set in and around the U.S. stories, Grimlock and the Dinobots were the stars of several stories while self-exiled from the other Autobots, including In The National Interest where they tried to help expose the Robo-Master hoax.

Towards the end of the series, the UK comics began a break-away storyline that branched off from the continuity of the American stories, beginning with Grimlock's decision to once again break his Dinobots away from the main Autobot force. Tired of Prime's pacifistic approach to protecting Earth, Grimlock was joined by several older Autobots like Prowl and Wheeljack, who had just recently been reactivated, and longed for the older, simpler days. Under Grimlock's command, they formed the Earthforce, a pro-active Autobot group based in Canada

 who regularly battled the two Decepticon forces under the commands of Megatron and Shockwave.

Issue #279 of the Marvel U.K. Transformers comic featured a story called "Divide and Conquer!" where Soundwave lead the bulk of the Decepticon forces on Earth against the Autobot Earthforce headquarters while Starscream attacked an oil tanker. Sent into battle by Prowl, the Dinobots routed the main Decepticon forces while Springer lead the Autobot Survivors, Broadside, Inferno, Skids, and Carnivac to defeat Starscream.

There was no specific ending for the Earthforce crew, but the issue of nucleon was resolved in a one-shot text story contained in the final Transformers annual (a hardback book containing new material released each year). Of the Dinobots, only Slag retained the ability to transform, until the discovery of new nucleon allowed all the Transformers previously empowered by it to regain their transforming abilities. The place in continuity of this tale is hard to determine. It followed on from the events at the conclusion of the American series, yet cannot fit in with American continuity as it puts Megatron in a situation he cannot possibly be in.

A few years after the conclusion of the original Transformers comic, the line was given a shot in the arm with the release of the new Transformers: Generation 2

toyline and an accompanying comic. Grimlock's toy was re-released for the G2 toyline in several colors including blue, but he continued to appear in his original grey color scheme for most of his appearances in the G2 comic.

With his transformation capabilities restored (the explanation for which was not offered in the American series), Grimlock was Optimus Prime's second in command in the so called Generation 2 series, aiding in the Autobots' war against the "second generation" of Cybertronians led by Jhiaxus

. However, he remained as rebellious and aggressive as ever, though it proved to be a mixed blessing - at one point his urge to combat Jhiaxus's forces led him and his troops right into a trap, while at another time, his willingness to defy Optimus Prime's orders and launch an all-out attack saved Prime from certain death at the hands of Megatron. When the Autobots and Decepticons united against Jhiaxus and the threat of the Swarm - a destructive by-product of Transformer reproduction - Grimlock was the joint leader of the ground troops as Prime and Megatron fought on other fronts, and survived the brutal conflict.

Grimlock appeared in his blue Generation 2 form in the short lived UK. Generation 2 comic series.

Years later, writer Simon Furman offered an "unofficial" conclusion to the Generation 2 storyline with "Alignment", a text story available exclusively through the British Transformers convention, Transforce, in 2001 and 2002. In the story, Grimlock is killed while trying to distract the Leige Maximo.

In his private thoughts, however, Grimlock considered Optimus Prime too weak to lead, seeking the position for himself. When Soundwave

 read his mind and learned of this animosity, Megatron was able to trick Grimlock and the Dinobots into switching sides, attacking and capturing Optimus Prime. To stop the turncoat Dinobots, two new ones were created: Snarl and Swoop. Ultimately, it was when Optimus Prime threw himself into harm's way to save Grimlock from an explosion that he accepted his mistake and rejoined the Autobots. In a rare display of modesty and humility, Grimlock emotionally apologised to Prime, admitted his jealousy of the leader, and accepted fault for the battle. The two subsequently patched up their differences.

Although content for the moment to remain a soldier, rather than a leader, Grimlock still had trouble accepting orders, only agreeing to help stem the tide of natural disasters ravaging Earth due to Cybertron

, or the Decepticons' control of the TORQ III supercomputer; with every piece of help he and his troops gave, Grimlock was never slow to add a scathing remark about the inabilities of the Autobots. That said, he was not unwilling to admit the failings of his own troops, either, and willingly took them to the time-displaced "Dinobot Island," where they trained in the wilderness and helped stop a Decepticon raid on the prehistoric paradise.

The final straw for Grimlock came when he and the Dinobots were injured in a Decepticon trap at an airfield. Enraged, Grimlock refused to take orders from Optimus Prime any more, and led the Dinobots away from the Ark. When the Autobots began to suffer from Cybertonium deficiency, Spike Witwicky and his girlfriend Carly attempted to persuade the Dinobots - who continued to function perfectly, as they had been built on Earth without Cybertonium - to steal some of the mineral from a Decepticon shipment coming in from Cybertron. Grimlock instead opted to lead the Dinobots to Cybertron itself, where they were captured by Shockwave

 and put to work in the Cybertonium mines, until Spike and Carly rescued them. Brought back to Earth, the Dinobots agreed to follow Prime's order again - until such time as Grimlock did not feel like it.

Third season

By the Earth year 2005, it seemed apparent that Grimlock had undergone some degree of a personality change, becoming more childish and petulant, rather than brutish and stubborn. Also of note, it seemed that, along with the other Dinobots, Grimlock remained in his Dinosaur mode almost exclusively, rarely changing back to his Robot form. Throughout 2006, he regularly participated in missions with his fellow Autobots rather than the other Dinobots, battling on the planets of Chaar, Goo, Dredd and Eurythma.

In episode 78, "Madman's Paradise", Spike and Carly hosted a banquet for a visiting ambassador. Daniel got bored and wandered off. Grimlock followed him, and they fell into a lost chamber where Quintessons banished their criminals to other dimensions. They slipped through to the other-dimensional realm of Menonia, and were tricked into fighting on the Red Wizard's side, only to find out that he was the Quintesson criminal, who overthrew the Golden One.

. Grimlock survived, however, and followed Tornedron back to Primacron's lab. When Tornedron turned on his master, like his predecessor, Primacron's complicated plans and equations could not find a way to stop him; Grimlock, on the other hand, randomly flicked a switch which reversed Tornedron's energy polarity, undoing the damage the now dissipating Tornedron had done. Grimlock decimated Primacron's lab while dancing around over his successful saving of the universe, dubbing it the smartest thing he'd ever done.

In a flashback in Maximum Dinobots #1 Grimlock lead the Dinobots in taking a Decepticon energon silo in Sub-Sector Nine on Cybertron.

In the Transformers Spotlight issue on Shockwave, Grimlock and the 'Dinobots' (sporting Cybertronian designs much like their War Within designs) appear in a story that partially pays homage to their Marvel G1 origin. Seeking payback for a humiliating defeat by Shockwave, Grimlock pursued him to prehistoric Earth (which Shockwave was seeding with Energon). In order to protect themselves against Energon surges, the Dinobots required alternate modes covered by a layer of synthetic flesh. Refusing to pick dying and thus weak Ice Age mammals for an alternate form, Grimlock chose to utilise more ferocious dinosaruian beast modes which were much more impressive. The Dinobots got the initial jump on Shockwave, as their attack was too illogical for him to understand, but he quickly recovered and dispatched the entire team, destroying their synthetic skins and sending them into stasis lock. Grimlock got the final laugh, as the Dinobot ship fired a pre-programmed blast into the surrounding volcanoes to unleash a flow of lava that engulfs all six Transformers until they were uncovered by human paleontologists in 2006.

  • Alternators Grimlock (2005)
Grimlock staged a comeback in 2005 as part of the Transformers: Alternators toyline, known in Japan as "Binaltech". Although the American toys offer no supporting fiction, the Binaltech series tells the story of how Grimlock was reborn in his new form.
While the Autobots on Earth were decimated by Cosmic Rust and restored in new "Binaltech" bodies through a joint partnership with human automotive corporations, Grimlock and the Dinobots were a part of the larger war raging in space. Unfortunately, Megatron struck at their primitive minds with telepathic alien lifeforms known as "Unleashers," which drove them to attack their fellow Autobots; with no other options, the Autobots were forced to counter attack, taking the Dinobots out of commission. Grimlock regained consciousness and vowed to do anything to return to the battle, and was consequently transported to Earth. His spark was implanted into the Autobots' newest Binaltech body, which combined all the aspects of the previous bodies. Now able to transform into a Ford Mustang GT, Grimlock immediately resented his new, non-traditional body, but came to make the best of it. He remains armed with his energo-sword, and also wields a stun laser.
The figure was also redecoed in white and blue with a different head as Wheeljack

His contempt for the weak kept him often at odds with Optimus Prime, but his hatred for all those who exploited their strength at the expense of others kept him always firmly on the side of right. Though he could bring a huge array of weapons to any fight, he preferred to close with his enemies, wielding his Energo sword in robot mode, or simply crushing his enemies’ limbs with his powerful jaw as a Tyrannosaurus.

Transformers: Energon

Another alternate-universe incarnation of Grimlock entered the fray in the Transformers: Energon line. Grimlock's toy – packaged with the similarly-redesigned Swoop – was a modern updating of his original figure. It still transformed into a Tyrannosaurus rex, but had one major change: Grimlock and Swoop could now combine to form a larger robot named "Mega-Dinobot". The characters' joint biography clearly draws on the Generation 1 cartoon incarnation of the original characters, presenting them as Autobots who are simple in speech and thought, but who make up for it in raw strength. Decepticons have been known to flee in fear when faced with the two Dinobots, as Swoop uses his aerial abilities to confuse and distract them, while Grimlock attacks from behind and stomps them flat before they know what hit them. Though heavily armed, the duo's preferred weaponry is their teeth and talons.

It comes as no surprise that longtime Grimlock fan Simon Furman intended to feature the characters in Dreamwave's Energon comic book, but the company's closure prevented this.

. In robot mode, he wields a flaming battle sword and can breathe fire in beast mode. Grimlock is partnered with fellow Dinobots, Snarl and Swoop. He debuts in episode 6, "Blast From the Past". Grimlock acquired his name while the damaged Megatron's head was surveying the Dinobots at Prof. Isaac Sumdac's laboratory. Megatron said, "And without more substantial robotics for my own body, my prospects are grim, locked in this prison of a lab." He is also the only one of the Dinobots to talk and the first to transform into robot mode.

Animated series

In "Blast From the Past" the Autobots visit a dinosaur-themed amusement park
Amusement park
thumb|Cinderella Castle in [[Magic Kingdom]], [[Disney World]]Amusement and theme parks are terms for a group of entertainment attractions and rides and other events in a location for the enjoyment of large numbers of people...

 where animatronic dinosaurs are on display, but Bulkhead accidentally breaks them. Professor Sumdac and Megatron rebuild the animatronic dinosaurs as technological wonders named the Dinobots, who go on a rampage under the Deception's influence until the attacks powered Sari's AllSpark key affecting Bumblebee and Ratchet's Electromagnetic blast against the Dinobots by making them conscious. Finding a way to control them, Megatron told Grimlock to attack the city by telling the Dinobots they are "fossil feeders" due to the way Earth vehicles are powered and that the Autobots are even worse. The Dinobots are lured away by the Autobots, with Prowl secretly placing them at the later named Dinobot Island in hopes that they'll live in peace. However, while expressing his rage at two birds defecating on him, Grimlock accidentally transforms to robot mode and finds his new form to his liking.

The episode "Survival of the Fittest" marks his, as well as the rest of the Dinobots, official side change when they help defeat Meltdown, Cyrus "The Colossus" Rhodes, and Meltdown's experiments.

In "Megatron Rising" Pt. 1, Optimus Prime, Prowl, and Bulkhead try to get the Dinobots to help them fight the Decepticons, but they refused saying that robots are their enemies. Upon them being told that they are robots too, Grimlock and the other two Dinobots end up fighting each other.

In "The Elite Guard", Optimus Prime leads Ultra Magnus and Sentinel Prime to the downed ship on Dinobot Island when they run into Grimlock and the Dinobots. Despite Optimus' warnings, Sentinel Prime charged them and got defeated. Ultra Magnus repelled them with the lightning he summoned with his hammer.

In "A Fistful of Energon", Prowl and Bulkhead are sent to the island where the Dinobots are, once again, to investigate the reports of a rampage. Soon enough, Grimlock heads right towards Prowl and Bulkhead, thinking something has made him hostile, but later discovering something is wedged between his foot, and yank it out.

Later, under Blackarachnia's seduction, Grimlock returns in the episode "Black Friday" to break out Meltdown. Out of the Dinobots, Grimlock had the most love for Blackarachnia, refusing to accept that she's using him when she departs, leaving him heartbroken.

In "Predacons Rising" the Dinobots are once again coerced into doing Blackarachnia's bidding, bringing them into conflict with the Autobots. In the ensuing battle, they are overwhelmed and defeated by Jetfire and Jetstorm.

During the Human Error 2-parter, Sari attempted to get the Dinobots' aid only to have a not so warm welcome. Though she managed to convince him not to attack with her techno-organic powers, Grimlock refuses to give the Autobots aid though he indirectly led her in looking for Snarl, whom he lost respect towards and considered a 'traitor' for befriending the marooned Scrapper.

He comes with a large, transparent orange sword with flame details that spring out when the sword is placed in his right hand and the wrist is twisted clockwise or counter-clockwise. A button on his dinosaur mode neck opens his mouth. The transformation sequence is very close to his original G1 toy, but with more details and a few minor steps added.
The box packaging and instructions mention the sword also being able to connect to his mouth as a "Jet flame breath attack," though there are no actual connection points in his mouth. This feature was probably dropped during production due to issues with getting the sword to actually fit inside his mouth.

Transformers: Timelines

This Grimlock is an evil version of the
Generation 1 character. It should also be noted that this Grimlock has Trypticon's colors.

According to the Tech Specs Grimlock was created as an experiment in artificial intelligence by the Decepticons which became too violent and Megatron shut him down. Optimus Prime then liberated Grimlock and let him work for the Autobots.

Initially Grimlock is a non-living machine without the ability to transform to a humanoid shape. Once granted an ember by the Omega Terminus he gains the ability to transform. His transformation seems to be tied to his emotions. When calm intellectual he gains a humanoid mode, but when enraged he is forced into dinosaur mode. Grimlock was reprogrammed by Optimus Prime to not be able to attack anything bearing the purple Autobot symbol, but after being granted an ember he seems to have overcome this limitation.
