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:
- Scrapper, the leader of the Constructicons, is a master designer who conceives the myriad structures the Construticons assemble. Although he's genuinely modest about his work, he's prone to bragging amongst his fellow Constructicons. He transforms into a wheeled front-load shovel and forms the right leg of Devastator. As indicated by a cut line from the original script of the Constructicons' debut animated episode, Scrapper was originally to be named Gravedigger.Bonecrusher is brawler by nature and specialises in demolitions work. He would enjoy the extra potential for destruction as Devastator if it didn't mean sharing the same mindspace as his fellow Constructicons. He transforms into a bulldozer , and forms Devastator's left armScavenger 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. He transforms into an excavator , and the right arm of Devastator. Originally to be named Scrounge, Scavenger was erroeously referred to by this name once in the Constructicons' debut animated series episode.Mixmaster might have a few chips loose in his logic centre, 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 forms Devastator's left leg.Hook (Glen in Japan) 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, but the time he takes to perfect his work and his arrogance are his weaknesses. He transforms into a crane , and forms the head and shoulders of Devastator.Long Haul is not fond of his role as transport, ferrying construction materials to and fro on a Constructicon building site, and although he accepts its importance, he would much rather be a full-time warrior. He transforms into a dump truck and forms Devastator's lower torso. In a children's coloring book, Long Haul is once mistakenly referred to by Scrapper's early name, Gravedigger.
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, due to the fact that 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.
