Demolishor is the name of several different fictional characters from the Transformers robot superhero franchise.

Transformers: Armada

Demolishor, sometimes spelt as Demolisher is one of the earliest created Decepticons of the toyline; and in the storyline, also one of the first to come to Earth from his homeworld - the fictional planet Cybertron. In the Japanese series, Demolishor's name was Ironhide, coincidentally the name of a fellow character from the Transformers series, later Irontread and also later Ironside.

Animated series

Transformers: Armada

Demolishor was a regular character in the show and one of Megatron's most faithful troops, whose loyalty to his Lord was always beyond any doubt. His transformation was that from a robot to a self-propelled track-laying multitube gun (indeed, a sort of a Cybertronian tank). He was extremely strong and acted usually in conformity with the principle «big strength is better than big brains», especially when it was necessary to crush or destroy something. He was of a serious and rather morose disposition.

He mostly acted as the muscle of the group, partnered with Starscream and Cyclonus to battle the Autobots. When meeting the 'Bots in single combat, however, he often lost because of his sluggishness.

Demolishor played no major role in the series aside from acting as Megatron's favored military tactician, prior to Thrust's arrival. In spite of his rough and grumbling nature, he was a true mate. Though Demolishor obviously had little liking for Starscream (and even fought him several times), he interceded for him with Megatron and saved his life twice, at any rate. Once Demolishor saved Starscream by cutting the power ropes the latter was bound with, when Red Alert and Smokescreen attacked him in the forest and tried to disarm him. However, after doing this, he declared to Starscream (who was surprised very much by such a friendly service) that he saved not him but the Star Saber (Episode 17, "Conspiracy"). But possibly Demolishor's most important act during this period was to smash through the doors of the Decepticon base at one point to save Starscream from Megatron's wrath ( Episode 23, "Rebellion").

In episode 43, "Puppet," he was heavily damaged by Nemesis Prime. Thanks to the Mini-Cons, he and several other Transformers got powerlinx upgrades, which meant he was much more powerful. His new color scheme of red and white was meant as a tribute to his Japanese namesake Ironhide and his new colors were a homage to G1 Ironhide. He fought against Unicron along with Optimus Prime, Galvatron, Jetfire, Tidal Wave, Hot Shot, Sideswipe and Cyclonus after Starscream was destroyed by Unicron, and was one of the few to survive the final battle after Galvatron sacrificed himself to end the war. His Mini-Con partner was Blackout. Demolishor was very fond of him and even risked his neck when Blackout was in danger during the battle with Unicron.

Transformers: Energon

In the show Transformers, after the battle with Unicron 10 years prior, Demolishor continued to follow the final order given by his presumed dead leader, Megatron to work with the Autobots, similar to what Starscream did in Transformers Armada, and was appointed a guard at Ocean City, one of the joint human/Cybertronian Energon mining operations on Earth.

Despite frequent conflicts with some of the Autobots there (especially Ironhide) and an unwillingness to follow the orders of Optimus Prime, throughout the series. Especially, when it meant he was left out of the fight, he generally served well, fighting strongly against the early Terrorcon attacks.

However, later in the show, when Demolishor beheld the sword wielded by Scorponok that had been forged from Megatron's spark, he could sense his leader's life energy, and found himself questioning his role. When Megatron himself was reborn and attacked Ocean City, Demolishor faced off against his leader, but could not bring himself to fire upon him, returning to his side. Though this far through the story, there were still some lingering doubts in Demolishor's mind, his experiences with the Autobots and humans clearly having affected him. He made his final decision, however, when he cast his concerns aside and pushed Megatron out of the path of Miranda II's Energon Grid, taking the full force of the energy, destroying his body. However, Megatron was able to recover his spark, and using the powers he gained by merging with Unicron's body, created a new body for him, bringing Demolishor back into the plot.

As sort of a final insult, Megatron diminished his intelligence, turning him once again into a loyal servant. Prior to this reconstruction in the show, Demolishor retained his original form of a missile tank (only now colored Constructicon Green), but after being recreated, his alternate mode became a dump truck, armed with a "Hyper Power" missile launcher. In this new form he was renamed Irontread in Transformers: Superlink, the Japanese version of the series. His new personality was highly aggressive and combative, and he would often perform backflips and beat his chest when excited. Despite his brainwashing, when Galvatron (the upgraded incarnation of Megatron) plunged himself into an Energon sun to prevent Unicron's victory, Snow Cat (Cyclonus' similarly upgraded form) and Demolishor were self-preserving enough to hold back and stay alive while their leader, Starscream and Mirage apparently perished.

Transformers: Cybertron

In the Japanese version of Transformers: Cybertron, Mudflap was the name given to Demolishor. He has no relation to the character Demolishor from Armada and Energon.

Transformers: TransTech

General Demolishor is a Transtech Military Police officer on Transtech Cybertron. He is a pompous, over the top, blowhard who enjoys using excessive force.

"Quietness is boring and ineffective, noise puts proper respect in citizens." - Demolishor

Shattered Glass

Demolishor is a member of the heroic Decepticons commanded by Megatron. Unlike most of the inhabitants of the Shattered Glass Cybertron, Demolishor seems to be a mirror reflection of an Armada character instead of a Generation 1 character.

Unlike the Armada character who is very determined, this Demolishor seems to be a bit wishy washy, not sure what he should do or why.

Transformers Cinematic Universe

Unlike most other Transformers named Demolishor, this character from Revenge of the Fallen turns into a construction vehicle. Demolishor is cowardly when there's no leader, and he isn't the brightest one, but he's powerful enough to fight with multiple foes. He can use his excavator mode's tracks as wheels to travel (either as a unicycle or bicycle) and attack by moving one over his head to crush everything in front of him.[8] Although Demolishor's alternate mode is a construction vehicle, he is not part of the Constructicon subgroup; rather, he is an individual Decepticon who happened to choose a similar guise to Scavenger (who is a Constructicon).

Demolishor protects a small Decepticon community in Shanghai after Megatron's death. He is the largest non-combined transformer seen in any of the Michael Bay films so far, although there are larger characters in the associated media.

Demolishor shares his model with another Decepticon, Scavenger. This led to confusion for several months by fans if Demolishor and Scavenger were the same character or different. In the film Demolishor is depicted as being primarily white, while Scavenger is red, but as Demolishor is seen only at night, his color is hard to see. Additionally most of the toys for Demolishor are incorrectly colored red, like Scavenger, making them nearly identical.


When the NEST and the Autobots come to Shanghai, China attempting to uncover a hidden decepticon, they find Demolishor and Sideways. Demolishor transforms and swats at NEST helicopters as he begins to make himself mobile. Demolishor proceeds on a highway in China. He destroys an overpass just as Optimus Prime transforms and jumps off the bridge. Optimus manages to dive onto Demolishor, grabbing onto his head as he proceeds down the highway. Optimus shoots him repeatedly in the head, while at the same time Ironhide damages one of his wheel joints in which breaks the wheel forcing the Decepticon to fall over, causing him to go off the road and crash. With most of his body damaged as a result and NEST surrounding him, Demolishor does not attempt to escape. Optimus asks him if he has any last words. He says "This is not your planet to rule. The Fallen shall rise again" before Prime kills him by blasting him right through the eye.

Transformers: War for Cybertron

Demolishor is a downloadable character for the 2010 video game Transformers: War for Cybertron.
