Constructicons

Transformers: Generation 1
The Constructicons (known as Buildrons in Japan), so named for their group job of design, engineering and construction for the Decepticon forces, are particularly notable for their status as the very first combining sub-group of Transformers, able to merge their bodies and minds together to form the gigantic Devastator.[2] [3] The individual members of the team include:[4] He transforms into a wheeled front end loader. He forms the right leg of Devastator He is the leader of the Constructicons even though he does not form Devastator's torso. He is a master designer who conceives the myriad structures the Constructicons assemble. Although he is genuinely modest about his work, he is prone to bragging amongst his fellow Constructicons. As indicated by a cut line from the original script of the Constructicons' debut animated episode, Scrapper was originally to be named Gravedigger. Voiced by Michael Bell. He transforms into a crane truck. He forms the head and shoulders of Devastator. He is the team's perfectionist second-in-command, who considers himself far too elite to deal with most of the "ruffians" that call themselves Decepticons. He is excellent at performing tasks which require extreme precision (including surgical operations), but the time he takes to perfect his work and his arrogance are his weaknesses. Voiced by Neil Ross. He transforms into a bulldozer. He forms the left arm of Devastator. He is a brawler by nature and specializes in demolitions work. Under this vicious personality is an underlying motive; he is a perfectionist at heart and wishes to destroy all he deems imperfect, including the Autobots. He would enjoy the extra potential for destruction as Devastator if it did not mean sharing the same mind space as his fellow Constructicons. A different Bonecrusher was in the 2007 live action version of Transformers. Voiced by Neil Ross. He transforms into an excavator. He forms the right arm of Devastator. He is an unashamedly pathetic Decepticon. Desperate to prove his worth to his team-mates, he uses his one true gift - his shovel's ability to detect various magnetic, ionic, electrical or gas readings - to locate items of value, although invariably, all he can usually find is junk. Originally to be named Scrounge, this became a derogatory nickname for him from the other Constructicons and Decepticons. Voiced by Don Messick. He transforms into a dump truck. He forms the lower torso of Devastator. He is not fond of his role as transport, ferrying construction materials to and from on a Constructicon building site, and although he accepts its importance, he would much rather be a full-time warrior. In a children's coloring book, Long Haul is once mistakenly referred to by Scrapper's early name, Gravedigger. Voiced by Gregg Berger. He transforms into a cement mixer truck. He forms the left leg of Devastator. He might have a few chips loose in his logic center, judging by the cackling with which he undertakes his role of materials fabrication. Although manic and erratic by nature, he is a genius of a chemist, able to mix chemicals in the drum of his concrete mixer alternate mode. He has also been known to insert solid objects—such as cars—into his mixing drum in order to turn out new building materials. Voiced by Frank Welker. The team's combined form of Devastator is brutality in its purest form—his sole purpose is to destroy anything and everything that gets in his way. It is ironic that the suitably intelligent Constructicons should sacrifice their thinking ability in their combined form, but simple-mindedness is a common limitation of the assorted other first-generation combining Transformers, because Devastator's thoughts and actions are limited to what his six components can agree upon at any given time. Consequently, Devastator seems like a being of instinct, lashing out at everything around him before contemplating the consequences, but he is also slow and lumbering and very easy to trip up. It should also be noted that Devastator is composed of 6 individual robots, compared to most other combiner teams who had 5 components (the exceptions being Monstructor and Piranacon). The only contradiction to Devastator's lack of a display of intelligence is in The Core, when his components' minds were temporarily controlled by the Autobots. He was able to detach the portion of himself made by Hook and complete a complex surgical procedure on Jazz (which put even Ratchet's skills to shame). When the surgery was complete, Hook returned to Devastator's combined form as if the whole operation was performed by the Autobot-controlled Devastator.

Animated series
According to the Autobot, Omega Supreme, millions of years ago, the Constructicons were the creators of the beautiful Crystal City on the Transformers' homeworld of Cybertron, which he was assigned the task of guarding. As a friend of the Constructicons, he was hurt the most when they were attacked by Megatron, who, seeking to bolster the forces of his then-small army, subjected the Constructicons to the Robo-Smasher, a device which reprogrammed their minds and turned them into Decepticons. In their first act as Megatron's troops, the Constructicons lured Omega away from Crystal City and demolished it, enraging Omega, who pursued the Constructicons across the planet. Eventually, he succeeded in capturing them and apparently restored their programming to its original state, but as the group returned to rebuild Crystal City, Omega learned that Megatron's reprogramming could never be undone—the Constructicons were still Decepticons, and more than that, Megatron had given them a new power: the ability to combine their bodies and minds into the giant known as Devastator. In the ensuing struggle with Devastator, the Robo-Smasher attacked Omega's mind. He was able to stop it before the reprogramming was complete, only to wind up losing his emotions. Filled with only hatred for the Constructicons, Omega relentlessly pursued them, until they finally fled Cybertron in a spacecraft, which Omega chased across the galaxy.

In 1984, the Constructicons joined with Megatron's forces on Earth, and their first mission was an impressive one - Scrapper designed a machine to transfer the other Decepticons' powers to Megatron, and while he battled Optimus Prime, holding the attention of the Autobots, the Constructicons invaded the Ark to destroy Teletraan I. Unfortunately for them, the Ark was protected by the Dinobots, but by merging into Devastator, they became more than a match for their prehistoric foes. The return of the other Autobots and the discovery of Megatron's deception spelled the end of the battle, however, as Hound distracted Devastator with a gigantic hologram, and Optimus Prime blasted the giant at just the right spot to force the Constructicons to disengage. They and the other Decepticons were then forced into a river of lava.

The Constructicons survived the river of lava along with the other Decepticons and continued to assist in Megatron’s plans of conquest. In the year 2005, Devastator was the Decepticons' primary weapon in the Battle of Autobot City with the absence of Menasor and Bruticus, tearing through the defenses and walls of the city and battling the Dinobots once more. On the return trip to Cybertron, it was Bonecrusher who advocated the "survival of the fittest" policy that saw many wounded Decepticons ejected from the shuttle, among them Megatron, prompting Scrapper to nominate the Constructicons for the new leaders of the Decepticons. Hook took great offense to the notion that the unpopular Soundwave would make a better leader than they would, leading to a mass brawl to decide who would be Decepticon leader. Later, on Cybertron, the Constructicons were blowing trumpets during Starscream's coronation but were cut off due to Starscream's impatience.

In the remainder of 2005 and throughout 2006, the Constructions maintained a smaller, but still present, role in the Decepticon army, lending their talents to the Decepticon/Quintesson alliance by constructing Trypticon out of a populated human city in only one night. Later, they built a planetary engine on an asteroid and battled on the planet Eurythma, aided in the overthrow of Paradron and took part in an attack on Japan. Although brief, the Constructicons even played a part in the battle for the Plasma Energy Chamber in 2007.

The Constructicons' voices were performed by Michael Bell (Scrapper), Neil Ross (Hook, Bonecrusher), Gregg Berger (Long Haul), Frank Welker (Mixmaster), Don Messick (Scavenger) and Arthur Burghardt (Devastator). The individual Constructicons are six of only ten characters to have appeared in all four seasons of the Transformers animated series (the others being Optimus Prime, Soundwave,Bumblebee/Goldbug, and Spike Witwicky), and they would continue to make brief, token appearances throughout the Japanese-exclusive Transformers: Headmasters series. Later, in the single episode of 1990's Japanese Transformers: Zone series, Devastator was among the nine Decepticon Generals assembled by the villainous Violenjiger. The veteran Decepticon was almost immediately defeated in this series, entombed beneath the earth by a river of magma unleashed by Dai Atlas. It's unclear if Devastator was killed or only incapacitated, due to fact that the Constructicons already survived magma's effects in "Heavy Metal War."

One of the most frequent animation errors concerning Devastator is that at some points he has a visor covering his eyes: at others the eyes themselves are visible. This was due to his full-figure profile on the animation model sheet being drawn with eyes, while the close-up head profile showed the visor. Another inconsistency involves the color of Mixmaster's mixing drum, usually seen in purple on Devastator. This is due to toy models (as seen in the 1985 Transformers product catalog) showing the drum as green on vehicular-mode Mixmaster, but in a soft gray (unique only to this unreleased version of Mixmaster) on a combined Devastator.
