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

Nothing is safe. From raw ore to living robots, it all goes into Mixmaster's grisly drum where it's reduced, refined, and recombined into virtually any raw material the Decepticons need. Watching Mixmaster prepare a new batch of materials is like seeing some mad alchemist at work, giggling and cackling over his creations with evil glee. It would be a stretch to call him a scientist; a better comparison would be to a Warlock throwing arcane scraps into his cauldron to complete a bubbling potion. His fellow Decepticons suspect Mixmaster of having a few wires loose in his logic center, but they can't argue with the results. He transforms into Devastator's left leg.

One time, he repeated himself a lot. This never happened again, but everyone assumes it was his standard vocal quirk anyway. City of Steel

Marvel Comics continuity

Mixmaster is the green and purple one.

Early in the Transformers' war on Earth, Shockwave used the stolen power of the Creation Matrix to give life to the first of a new generation of Decepticon warriors, the Constructicons. Mixmaster and the other Constructicons were immediately given a mission upon their coming online -- construct a communications tower to transmit a message to Cybertron. A truckstop was raided for raw materials, which attracted the ire of trucker Bomber Bill, who, with the aid of the Autobots, managed to destroy the tower Mixmaster and the other Constructicons had built. The Next Best Thing to Being There!

Mixmaster and the Constructicons, after troubleshooting their union as Devastator, were sent by Shockwave to abduct Buster Witwicky. Their attack was called off to regroup when Soundwave discovered Buster held the rest of the Creation Matrix in his head. Devastation Derby!

After Megatron's retaking of Decepticon command, Mixmaster and the other Constructicons were charged with building perimeter defences around their headquarters located at the base of a coal strip mine in eastern Wyoming. Devastator's services were again required when the Autobots staged a surprise attack, but they retreated once they had what they needed. Command Performances!

When the Decepticons set out to foil Joy Meadows' attempt to expose the Robot Master scam, Mixmaster transported Megatron when he went to intercept Joy's camera crew and ended up wielding Megatron in his gun form when he battled Swoop and Centurion. He was later among the Decepticons who battled the Dinobots, where Swoop got his own back by lifting him up and smashing him into a cliff. In the National Interest

During Ratbat's command, an attack was ordered on the combined Autobot forces on Earth's moon while Blaster and Grimlock dueled for leadership. Under cover of battle, Mixmaster and the other Constructicons retrieved the remains of several fallen and captured Decepticons. Totaled!


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

Mixmaster chose to work for Megatron once he and Shockwave split the Decepticon faction on Earth. He and Long Haul ran into the Autobots Prowl and Wheeljack while guarding Megatron's ozone rocket, but didn't last long in the fight -- Mixmaster ended up leaping over a rushing Wheeljack and landing hard on Prowl's fist. Starting Over! At Megatron's side during the Enclave, Mixmaster was present when a hidden sniper began taking potshots at his leader. He returned fire along with Soundwave and Motormaster, and Shockwave's minion Headstrong fell to the floor from his perch, an apparent assassin sent by his leader. This led to an enormous skirmish between the two factions, who little realized it had been arranged by some canny Autobot surveyers. The Bad Guy's Ball! Mixmaster was last seen charging into battle with the other Decepticons when they made an ill-fated siege on Autobot Earthbase. Divide and Conquer!

He's also a known dealer of Syk, a forbidden circuit-booster. Zesty. Secrets

Marvel UK future timelines

In 2008, Decepticon Commander Soundwave gathered his lieutenants and told them to prepare for war against the Autobots. Mixmaster was present at this war council, apparently representing the Constructicons as their ranking officer! Space Pirates!

Timelines Classics comics

Note: The Classics comics continue from the Marvel G1 comics, but disregard G2 and Marvel UK.

The Constructicons were among the troops that Megatron covertly rebuilt on Earth after Bludgeon's defeat and exile. But both Mixmaster and Hook were curiously absent from team, with the enigmatic Hightower in their place. Hightower himself joked about stripping enough spare parts off of Grimlock to "build a new Hook." Crossing Over: Part 6 It's unclear if whatever had happened to Hook had also caused Mixmaster's disappearance. Hightower has a similar enough personality to Mixmaster that they may be the same individual, though if that's the case, then it's odd that he was rebuilt with Hook's alt-mode.

Dreamwave comics continuity

Mixmaster was a member of the Constructicons beginning at least nine million years ago, when he and his partners helped prepare Cybertron for conversion into a mobile juggernaut under Megatron's direction. The War Within

At one point, the Constructicons designed the original combiner process, and applied it to themselves to create their alter-ego Devastator. Devastator was mentally unsound due to problems in their programming prototype, but Megatron insisted they keep him around anyway for his raw destruction power. The creation of Devastator spawned several copycat programs among Autobots and Decepticons alike, and soon at least a half dozen "Special Teams" were in combat on both sides. They began causing far too much damage on the planet, however, and so by the time of the Dark Ages the Crisis Intervention Accord was issued banning any group of combiners from all serving together on any one faction -- they could be a neutral group or separated soldiers, but no more. The Constructicons were the first to break these accords and join up as a unit with Ratbat's Ultracons. The War Within: The Dark Ages

At some unknown time, the Constructicons made their way to Earth in order to serve with Megatron and the lost crew of the Nemesis in the 1980s. Like all Transformers, they vanished after the destruction of the Ark II, but were reactivated by Lazarus in the 21st century. Mixmaster and the Constructicons formed Devastator and began attacking California after regaining their free will, but were ultimately destroyed. Their remains were taken into custody by Earth Defense Command.

IDW comics continuity

Mixmaster and the other Constructicons apparently joined up with Megatron after the labor shortages for engineering robots cut them loose. Instead of actively participating in the tournaments, however, they lent their talents to quickly clearing random deserted areas and building new arenas on-site shortly before the matches, so that the games were constantly moving. The Constructicons were very efficient in their work -- they would even melt down Empties found at their construction sites in a pool of Mixmaster's solvents. Megatron Origin issue 2

Hundreds of years ago, Mixmaster was one of the Cybertronian scientists Thunderwing consulted with when he uncovered Cybertron's energy problems. Stormbringer, Part 1

When the Constructicons arrived on Earth, Mixmaster transformed with his teammates when they awed the crowds in New York City. At first, he played along with Scrapper's claims that they were benevolent aliens. Ever the nut job, Mixmaster did not join in the attack, but instead took a moment to examine the building materials that the humans used. He told Scrapper that they were soft, just like the humans. All Hail Megatron issue 1

Devil's Due G.I. Joe vs. the Transformers continuity


He's got legs, and he knows how to use 'em.

The ruthless terrorist organization known as Cobra dug dozens of Autobots and Decepticons out of their four-million-year resting place and began rebuilding them into a Cobra-controlled army. However, with Wheeljack and Bumblebee's help, the mind-controlled Transformers were awakened, and the very cheesed-off Constructicons, including Mixmaster, descended upon their previous captor, Dr. Mindbender.

Their surroundings were soon under attack by Autobot and G.I. Joe forces, requiring Mixmaster and the other Constructicons to combine into Devastator. Ultimately, Devastator was brutally defeated after Devastator fatally wounded Hound, sending the Autobot's friends into a berserker rage. G.I. Joe vs. the Transformers

  • Constructicon (Constructicon, 1992)
This European exclusive version of Mixmaster was yellow, but with the darker purple from the original toy instead of the lighter Generation 2 shade, and came with no Devastator parts. This toy was also not officially named, as he came on a card shared by the other Constructicons.

Generation 2

  • Mixmaster (Constructicon, 1993)
The missile launcher mechanism was removed for this release, as was the single-tipped missile.


  • The hose/gun/cannon/thingy that Mixmaster uses to spray whatever is in his mixing drum at the time often changed its shape during the G1 cartoon. In his first appearance alone, it changed three times.
