The Constructicons, 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 (Devastar in Japan). The individual members of the team include:
* Bonecrusher (Demolitions)
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. Bonecrusher was also in the 2007 live action version of Transformers.
* Scavenger (Mining and Salvage)
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.
* Scrapper (Construction Engineer)
He transforms into a wheeled front-load shovel.
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.
* Hook (Surgical Engineer)
He transforms into a crane.
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.
He is known as Warnocker in Japan.
* Long Haul (Transport)
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.
* Mixmaster (Materials Fabrication)
He transforms into a concrete 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.
The team's combined form of Devastator is brutality in its purest form.
