The name or term Slag refers to more than one character or idea. For a list of other meanings, see Slag (disambiguation).

Slag is the Dinobot most likely to live up to the team's bad reputation. Slag is surly, mean-spirited, nasty, and disturbingly violent, to the point where it really is a wonder he's not a Decepticon. Slag will fight anyone, over anything, at the drop of a microchip, and fight dirty. Slag enjoys nothing more than reducing his enemies (and he's more than willing to include annoying Autobots on that list) to pools of molten metal with his fire-breath. He'd swim in the pools to celebrate if he could.

None of the Dinobots really like Optimus Prime, but he and Sludge share an especially intense dislike of him. But it's not just Prime's orders he questions. He'll even mouth off at Grimlock every now and then, but somehow does not end up as scrap or lunch. Slag's bad attitude means the rest of the Autobot forces are unlikely to come to his aid when he bites off more than he can chew.

"Me Slag no like anything."

Marvel Comics continuity

Generation One

Note: Events from the UK-only comic stories are in italics.

Slag was constructed without the necessary emotional dampeners that would allow him to regulate his moods and rage. This fact made him unpleasant company at the best of times, but also caused a regular glitch in his circuits, turning him into a raging homicidal berserker for a brief period every four million years. Shortly before leaving aboard the Ark with Optimus Prime and the rest of the Autobot crew, Slag experienced one of these "glitches" and wiped out his entire tactical unit. His fellow Dynobots managed to cover up the incident, and Prime and Autobot High Command never learned about it. The 4,000,000 Year Itch!

When the Ark computer detected Shockwave on Earth, it rebuilt Slag and the other Dinobots and sent them to battle him. The Last Stand The Dinobots managed to overcome Shockwave but the battle left them submerged in a tar pit. Slag was the first Dinobot to be found and reactivated by Ratchet, after a few million years, and soon joined his fellows in helping Ratchet battle Megatron. Although how much help they actually were is debatable. Repeat Performance

After the Dinobots had headed off on their own, the Autobots discovered their neural relays had burnt out, sending them berserk. Slag was found charging around a desert by a team led by Jetfire, who put a spying Laserbeak to good use by stuffing him into Slag's jaws. Dinobot Hunt

After Slag was repaired, he and the Dinobots headed out on their own again, battling Megatron's Decepticons to try and help Joy Meadows with her expose In the National Interest and then Galvatron. Fallen Angel He then returned to the Ark with the other Dinobots to successfully petition for Grimlock to be made Autobot leader. King of the Hill

Slag joined the other Dinobots in battling the Predacons Grudge Match and then pursuing Sky Lynx after he foiled Grimlock's plan to capture the renegade Blaster, breaking off when Blaster surrendered to them. Spacehikers He then watched the duel between Grimlock and Blaster on the moon's surface before being attacked by Ratbat's Decepticons. Totalled

After Optimus Prime had resumed command of the Autobots, he took Slag to Earth as part of a team that rescued Highbrow from Scorponok's Decepticons. When Optimus Prime and several others were shunted into limbo, Slag and the others ended up mistakenly attacking a group of Autobots from the future, with Slag getting thrown around by Ultra Magnus. Time Wars

As temperamental as he was, he at least had the sense to point out during the Underbase fiasco that the people of Tokyo are not well aware of Transformers as a whole, and possibly mistook the Dinobots for movie props. Unfortunately, this was right before the Dinobots had to deal with Starscream, and like his teammates, Slag got, well, slagged. Dark Star

Slag was eventually brought back online by Grimlock using nucleon, along with the other Dinobots. All This and Civil War 2 They took control of the Ark and set about reviving more Autobots The Void before heading to Cybertron to battle Unicron On the Edge of Extinction and a group of demons from below the planet's surface. The latter battle left Slag in a good enough mood to give HiQ a ride back to base. Still Life

Slag was among the handful of Autobots who survived the ambush by Bludgeon's Decepticons on Klo. After fighting off a small patrol sent to find them, they joined Optimus Prime, the Neo Knights and the rest of the Autobot army who had been revived by the Last Autobot in trouncing the Decepticons for good.

Marvel UK future timelines

In 2008, Slag and the Dinobots were one of several special units unleashed on the Decepticon attack force when Scourge and Cyclonus led the 'Cons on a siege of the Autobots' main base on Cybertron. Slag was seen barrelling through the Decepticon forces like a living juggernaut. Autobot High Command soon learned this assault was only a distraction, however, engineered by Unicron himself who was reconstructing himself on the planet of Junk. When Smokescreen returned from Junk with this news, Rodimus Prime gathered Scattershot, Grimlock, and the rest of the Dinobots with him to make an assault on Junk. Much to Rodimus's dismay, Slag and the Dinobots didn't hold back at all when attacking the Junkions Unicron had mind-controlled into doing his bidding, and tore through them as if they were any other enemy. The Legacy of Unicron!

Note: These stories do not fit into the normal Marvel continuity. See Earthforce for details.

Sometime shortly after the Matrix Quest, Slag and his fellow Dinobots were revived by Grimlock and returned to action in the Autobot army. Their more brutal methods didn't sit well with Optimus Prime, but ultimately he chose to leave Grimlock in charge of a special Earthforce, guarding the planet while he led the Ark's crew out in space to deal with the threat of Unicron. Break-Away! While the Autobot Earthbase was under construction, Slag and his fellow Dinobots decided to engage in an Earth custom known as April Fools' Day and have a little fun at their leader's expense. Slag used his vast technical knowledge to rig up a fake video message from Decepticon commander Shockwave, and the Dinobots used it to lure Grimlock out into a blizzard, convinced that he was going to a one-on-one duel with the Decepticon. Instead, he found a snowman with a cardboard sign, proclaiming him an "April Fool". Amusing as it was, Grimlock was last seen heading towards the Dinobots with a massive snowball over his head, so he might not have taken it too well. Snow Fun

When the Survivors joined up with Earthforce in order to get help for their ally Carnivac, Slag was part of the strike team that went to attack the Mayhems' island, and he fought the Pretender Stranglehold. Where Wolf? He was present at Earthbase for the unveiling of Wheeljack's new defense system The House that Wheeljack Built! and, shortly thereafter, fought back against a major Decepticon offensive led by Soundwave. He roasted the Constructicon Scavenger with his flame breath, and the 'Cons eventually retreated. Divide and Conquer!

With the sort of bad timing that only happens in comic books and soap operas, Optimus Prime came to Earthbase for a tour and inspection right when Slag's next 4,000,000 year berserker rage came due. This led to a hilarious romp through Earthbase, as the Dinobots desperately attempted to keep Slag under control while Grimlock tried to keep Prime unaware of what was going on. Comedy gold! The 4,000,000 Year Itch!

Later, when Snarl was suffering from Corrodia Gravis, the Autobots were forced into the unpleasant circumstance of seeking out the only known compatible Transformer for a transfer: Starscream. What's worse, their petition for aid came right in the middle of Megatron and Shockwave's assassination attempt on the treacherous Seeker. Forced to fight for Starscream's life, Slag held his own against Megatron in combat. He rear-ended the Decepticon with his horns and then set him on fire with his flame breath. Megatron tore out of there as if his reactor linkage was on fire. Which, incidentally... The Lesser Evil!

Another Time and Place

Several months after the golden age of Cybertron was reintroduced, more and more Transformers were succumbing to the effects of Nucleon. Slag was the only Dinobot still able to transform at this time. When Grimlock received information that the Hydrus Four facilities had reopened and discovered a means of reversing Nucleonic changes, the Dinobots jumped at the idea. Despite Prime's half-hearted warnings, Slag and his teammates followed Grimlock back to Hydrus Four in the hopes of becoming Transformers once again. They were followed by the "exiled" Decepticons, however, and a battle with a huge native creature delayed the Dinobots long enough for Bludgeon's crew to get ahead of them and take over the Nucleon facility. The Dinobots were laid low by a Holocaust Trigger, overloading their sensory circuits so that they were helpless before the Decepticons. Cruelly tortured, the Dinobots were still left alive so that they could witness the rebirth of Megatron, thanks to the Nucleon infusions Bludgeon was feeding him. Luckily, the Autobots had long since learned to become worried whenever the Dinobots were out of sight for too long, and had followed them to Hydrus Four. Roadhandler, Tote and several Micromasters managed to free the injured Dinobots, and an Autobot strike force brought down their Decepticon captors. The Nucleon reversion process was a success, and Slag and his comrades were restored as fully operational Transformers. Another Time and Place

Generation 2

Slag and the Dinobots were fighting alongside Grimlock and a small group of Autobot firestormers when they uncovered the Cybertronian Empire and their terraforming measures. After calling in Optimus Prime and the rest of the Autobots, they became part of a major offensive against not only Jhiaxus and his ilk, but everything they represented. War Without End! Despite Prime serving as overall commander, however, Slag and his buddies were still Dinobots first and foremost. So when Grimlock wanted to take first strike action against Prime's orders, there was no question whom they'd follow. Slag and the others were captured almost immediately, though, and only escaped thanks to the timely intervention of Optimus Prime and his more loyal group of soldiers. Devices and Desires!

Slag continued to fight alongside the Autobots with his Dinobot comrades, on both Earth and Ethos. The Gathering Darkness Escalation! Later, after the Autobots forged an alliance with the first-generation Decepticons against the Cybertronians, the Dinobots got into the spirit of things—they teamed up with Headstrong and Weirdwolf in a metal-munching contest to see who could chow down on the most Cybertronians.

Man, too bad Hun-Grrr and Skullcruncher weren't there to make it a real contest. Total War

In the final battle with the Swarm, Slag was seen arranging the alliance's defenses against the voracious creature. He later gave his life in a futile attempt to protect Slingshot from the Swarm, proving once and for that all Dinobots truly do care about their other long as they're also obnoxious loners. A Rage in Heaven!

One angry mother slagger!

Slag was developed, along with his fellow Dinobots Sludge and Grimlock, after the Autobots discovered dinosaur bones in their volcanic headquarters. Inspired by the power of the prehistoric beasts, Wheeljack and Ratchet built a trio of Dinobots to add firepower to the Autobot forces. The Dinobots proved too dangerous at first, and Optimus Prime ordered Wheeljack to abandon the Dinobot project. Wheeljack continued improving the trio of titans in secret, crafting memory components that made them smarter and easier to control. When the rest of the Autobots were captured by the Decepticons at the Great Falls hydroelectric power plant, Wheeljack dispatched the Dinobots to free their comrades and destroy the Decepticons. The Dinobots succeeded in forcing a Decepticon retreat and were welcomed as members of the Autobot team. S.O.S. Dinobots


I know he's a raging sociopath...but he's so cute!

Later, when the Dinobots were sent to Cybertron after trying to secure Cybertonium, Slag rammed Shockwave and then tried to turn him into a chew-toy. For this, the logic-driven Decepticon altered the Dinobots' memory circuits and put them to work in the Cybertonium Pit. Two squishies ended up saving them. Desertion of the Dinobots, Part 2

During the Battle of Autobot City, the Dinobots battled Devastator. Slag was the only one that managed to get a hit on Devastator, ramming into him at full speed. After evacuating Autobot City in the wake of Galvatron's attack, the Dinobots refused to leave, and Kup was forced to push Slag into the ship. Possibly to avoid being killed, Kup told the Dinobots about one of his encounters with an Ick-Yak. The Dinobots, along with Kup and Hot Rod, were shot down and crashed on Quintessa. The Dinobots searched for the two Autobots, with Grimlock believing they were close by, but Slag disagreed saying that Grimlock was "Full of beryllium baloney". They started hurling insults, and things might have turned violent, had Wheelie not appeared and pointed them in the right direction. He and Sludge broke down a door as Sharkticons prepared to execute the Autobots, giving a belated "Excuse me!" to a Quintesson prosecutor—who was being crushed under the combined weight of Slag, Sludge, and the door. Later, Slag literally burned the butt of a god. TFTM

Slag was one of the Primitives who were called by Primacron's assistant to battle Primacron's newest creation, Tornedron. When Grimlock was believed destroyed when Trypticon crashed on him, Slag took command of the Dinobots. He came up with an incredibly innovative strategy—lead the Dinobots away until he got a better idea. Hun-Gurrr thought it was the best idea yet. After Tornedron dispatched the other Primitives, Slag and the Dinobots attacked him, only to have their energy sucked from them. Fortunately, Grimlock survived Trypticon's weight and destroyed Tornedron, fixing everything. Call of the Primitives

So cute when he's not killing things.

In the year 2011, Slag, along with his fellow Dinobots, was deployed by Wreck-Gar to deal with the sudden invasion of the Decepticon forces. Slag and his team attempted a resistance but were quickly disabled by one of Mindwipe's hypnotic spells, which forced them all to fall asleep.

Dreamwave comics continuity

Slag was chosen by Grimlock to join his commando unit, and was with them in the Dark Ages when they split off to become the Lightning Strike Coalition. Upon learning that Jetfire was meeting with Shockwave in the Neutral Territories, Grimlock took the Dynobots to kill them for treason. The others, however, were more worried about the new Decepticon battlestation that was massacring the Prowl's Autobots (Slag didn't care about the bots, he wanted a piece of the action). Grimlock got pissed, poked Slag, and ordered him to follow his orders or get physical. Swoop finally convinced Grimlock to let them go while he went for Jetfire and Shockwave. After the battle, they discovered that someone had taken Grimlock and Jetfire, and there was no sign of Shockwave. When the Fallen was discovered, the LSC were forced into a temporary alliance with Shockwave's Decepticons to rescue Grimlock and the others.

Despite the truce, Slag still decked Shrapnel. Nobody cared. The War Within: The Dark Ages

After the Ark and the Nemesis crash-landed on Earth, the Dynobots followed the Insecticons there. They owned the Insecticons, who subsequently played dead until Grimlock and Slag got bored and wandered off. However, the Dinobots became trapped in stasis lock. After awakening, Megatron captured the Dinobots, using their imprisonment to force Grimlock to side with the Decepticons. Grimlock freed them after Shockwave captured Megatron and Optimus Prime. After returning to the Shockwave-controlled Cybertron, Octane poked Slag in the head and called him a "primitive".

Octane doesn't have a body anymore. War and Peace

Slag met Grimlock in the brig. Being two big, burly tough bots they formed a pecking order based on who ticked off the highest ranking commanding officer to get brig time. Slag won with a Vice Admiral and a lasting friendship was born. The two decided to form the Dynobots (not Dinobots) around the totally anarchic principle of no rules, no preconceptions. Maximum Dinobots issue 2

Slag and the other Dynobots followed Grimlock to revenge themselves against Shockwave, who blew up a cache of energon they had stolen. When Shockwave traveled to Earth, the Dynobots pursued him. Slag appeared to be Grimlock's go-to tech specialist, originating the idea of organic beast modes as a defense against energon overload. That's pretty innovative for a guy who spends most of his time thinking how better to kill everyone around him. Sadly, it did not protect the Dynobots from Shockwave's energy blasts, which melted the artificial skin and caused the Dynobots to go into stasis lock due to excessive Energon radiation. Due to a dead man's switch, the Dynobots' ship (the Skyfire) blasted a volcano that buried everyone in molten lava. Spotlight: Shockwave

The Dynobots were eventually excavated by Skywatch, and though Grimlock was the first to be brought back online, he was freed from Skywatch's control through a virus implanted by a Machination spy (under orders from Scorponok). Scorponok wanted Grimlock to join him, but Grimlock refused, fought Scorponok and escaped, vowing to find and rescue Slag and the other Dynobots. Scorponok, however planned to take control of the Dynobots himself and use them to assassinate Grimlock. Spotlight: Grimlock

Slag and the other Dynobots were revived under strict mental control. No way that could fail. Nope. None. Not in the least little chance. No likelihood at.... what? They got loose? Ahem, as I was saying. Slag was just a little bit ticked off. Maybe it was being betrayed and blasted in Grimlock's plan. Maybe it was being locked in stasis underground for thousands of cycles. Maybe it was being mind-controlled. Maybe it was just plain Slag. Probably just plain Slag. Maximum Dinobots issue 02

While he was content initially to watch Grimlock being attacked by hordes of Sunstreaker clones, Slag soon intervened, making a clear point about teamwork. Slag was pretty ticked off to be rescued by the Monsterbots. Maybe it was.... no, probably still just plain Slag. Maximum Dinobots issue 03

When it came time to attack Scorponok's base of operations, Slag was simply too slagging pissed to even speak for 24 pages. But he was very prone to smashing things. Maximum Dinobots issue 04

Once Shockwave showed up Slag was ready to evacuate the area and let mono-eye and mr. pinchy-nok fight it out themselves. None of the Dynobots could really bring themselves to leave so they joined the fray, going after Shockwave then Scorponok in turn. Slag is probably pissed he didn't get to take out either of them. Still, he did get a pardon for several thousand cycles of desertion so hopefully not too pissed. Maximum Dinobots issue 04


Generation One

  • Slag (Dinobot, 1985/1986/1991/1992)
    • Japanese ID number: C-28
    • Accessories: "Energo Sword", "Electron Blaster", "Rocket Pod", 3 rockets
G1Slag toy

This... good enough for... Slag!

Slag was released as part of the second series of Transformers in 1985. The toy transformed into a robotic Triceratops, and came with a missile launcher that could fit in the shoulder socket of both the robot and dinosaur, a red sword, a silver "electro blaster" and three silver rockets. Like many Diaclone-era toys, Slag had a conspicuous driver compartment contained in his chest.
Slag was later re-released in the European-markets "Classics series. In Japan, he and the other Dinobots were offered as mail-away items during Operation Combination, at a cost of 2300 yen (his original retail price) and two robot points.

Generation 2

  • Slag (Dinobot, 1993)
    • Accessories: "Kinetic Sword", "Blaster Gun"
The original Slag toy went through several iterations in the Generation 2 line. First, he was re-released in the original silver base color; the only notable difference in the toy proper is the inclusion of the "AUTOBOT" tampograph on one of his robot-mode legs.
The toy then had its silver changed to red, and then changed again to dark green. The final green coloration is the most common, while the red and silver variations go for a little more on the secondary market.
All three versions retain his original sword and rifle (which were renamed), but do not have the rocket pod or missiles from the Generation One release.


  • Slag's original toy was originally a Diaclone Dinosaur Robo Triceratops. In the Diaclone lore, this dinomech was a pilotable vehicle that could travel at speeds up of to 250 kilometers per hour and was designed for grasslands operation and melee combat. It also had a slightly different color scheme for its robot-mode bits.
  • The European exclusive Action Master Decepticon Charger cribs Slag's quote, his function, much of his bio, and his Tech Specs. Whether there was any relation intended between the characters or if the copywriters just got lazy is unknown.
  • Apparently, Slag also smokes...something, because he made an ashtray out of Octane's head in the Dreamwave comics.
