Beneath the gibbous moons of Cybertron, in the great dark spaces of the sunless void, far beyond the realms of man's childish reachings, does the great dread Monstructor have his origin. A being that seems instinct with some fearful and unnatural malignancy, his form like a robot and a deep great shadow at once, his very presence is said to drain light and life from the world around him, feeding his ancient hunger. A palpable cloak of dread follows his movements, and the very sight of his summoning and formation has driven sane beings beyond the bounds of madness. All living things, mechanical or organic, decay and die at his merest touch.
Monstructor is the channel for an evil beyond the darkest Decepticon imagination, and far beyond the puerile concerns of the insignificant beings who make up his composite form. He longs for the day, foretold in darkness, when he shall be split asunder no longer, and will rise one final time, free to travel the stars, from world to world, extinguishing all life sparks, ravening for delight.
Monstructor's body is the combined form of six Pretender Monsters:
Devil's Due G.I. Joe vs. the Transformers continuity
The Pretender Monsters, as individuals, had attacked the inhabitants of the undersea Autobot base; later, they confronted an attacking GI Joe force as Monstructor. The titan proved unstoppable at first, his energy-leeching fields draining enemy equipment and causing at least one pilot to instantly age before crashing.
Monstructor's triumph never came to completion, though, as the Joe laser squad targeted his head module, causing it to explode. The combiner robot collapsed into a shower of unconscious Decepticons.
IDW comics continuity
Monstructor was the first gestalt. Created by Jhiaxus under the direction of Nova Prime, they were intended to be the ultimate fusion of mind and body: a vast amount of intellect combined with unparalleled strength. Unfortunately, they were driven into insanity by the merging process, and became monsters. After Nova Prime departed Cybertron in the Ark, Omega Supreme locked them in a dimensionally-displaced prison to live out the rest of their horrid existence.
Eventually they escaped their dimensional prison and tracked down and attacked Omega Supreme, but were defeated by Optimus Prime. Despite Omega Supreme's protestations about the dangers of gestalt technology falling into Decepticon hands, Prime had them taken into custody in an attempt to repair their shattered minds.
It failed and they fell into Decepticon hands Dead Universe. Monstructor was then installed as one of the terrible, pretty much invincible Guardians of a Nega-Core. Under the mental control of Jhiaxus, he stands ready to destroy anyone who would try to stop the Expansion., and were later abducted by minions of the
- Monstructor (1989)
- Monstructor is formed by combining all six individually-carded Pretender Monsters. Much like the earlier Transformer combiner teams, he requires the attachment of separate accessories —his head, waist, fists and feet— to complete his robot mode. However, unlike earlier combiners, the separate pieces can all be stored on the individual team members; they fit on the backplates of the Pretender shells. As his individual components are not much larger than a Micromaster, Monstructor is the smallest of the Generation One combiners, standing about the same height as regular toys like Hot Rod... yes, even shorter than the Micromaster Six-Teams' combined forms.
- Monstructor was the final Generation One combiner released by Hasbro, and the only one to not be released in a gift set in any market.
- Monstructor is one of the few Generation One toys that has no boxart. However, Dinoking did.
- In early solicitations from Hasbro, Monstructor was called "Titanus."
