The Builders were created by writer jonathan_hickman with artists Jerome Opeña and Dustin Weaver. They were first seen in a cryptic vision in `Avengers` (Vol. 5) #1, published in December 2012, but were formally introduced in `Avengers` (Vol. 5) #3. Their introduction was a cornerstone of Hickman's long-form, multi-year narrative that redefined the cosmic landscape of the Marvel Universe. Hickman conceived the Builders as a force of cosmic order pushed to an extreme, genocidal conclusion. They were designed to be a threat so vast and overwhelming that it would take a united galaxy, led by Earth's heroes, to even stand a chance against them. Their visual design, often stark white or black with elegant, elongated forms and runic symbols, evokes a sense of ancient, alien, and godlike power, distinct from the more colorful and Kirby-esque designs of entities like the Celestials or Galactus. Their story serves as the primary catalyst for the `Infinity` event, which in turn was a major stepping stone toward Hickman's ultimate climax in the `Secret Wars` storyline.
The in-universe history of the Builders stretches back to the dawn of time itself. They were the very first race to achieve sentience in the nascent universe. Born from the primordial chaos, they evolved an innate understanding of the fundamental laws of creation and physics. They saw the young universe as a garden to be tended and shaped, a system to be perfected. For billions of years, they were a force of pure creation and cultivation. Their greatest achievement was the construction of the Superflow, a network of trans-reality pathways that allowed for faster-than-light travel between star systems, effectively connecting the disparate parts of the universe into a cohesive whole. They seeded worlds, guided the evolution of promising species, and established a framework for galactic civilization. The relationship between the Builders and the celestials is one of cosmic antiquity and some ambiguity. As explained by Captain Universe, the living embodiment of the universe itself, the Celestials were the “architects” of the cosmos, creating the grand blueprint. The Builders, in contrast, were the “masons” and “engineers,” the ones who carried out the work, building the structures and systems that allowed life to flourish. For eons, they existed in a form of symbiotic balance. However, a fundamental schism eventually occurred within the Builder society. As they shaped life, they also encountered concepts they deemed “errors”—imperfections, chaos, and evolutionary dead ends. A faction arose that believed their role was not just to create, but to prune the garden. This faction advocated for destroying worlds and species that did not fit their vision of a perfect, ordered system. This ideology eventually became dominant, transforming the Builders from creators into cosmic-level eugenicists. From this new philosophy, they created the Gardeners, a sub-species engineered to travel ahead of their main fleets. These Gardeners, including the beings known as Ex Nihili, would arrive on “feral” worlds and use powerful Origin Bombs to accelerate or rewrite evolution, judging the results. If a world's evolution was deemed a success, it was cultivated. If it was deemed a failure, it was sterilized. This process was repeated across countless galaxies for millions of years, solidifying the Builders' reputation as both gods of creation and harbingers of destruction.
To date, the Builders have not appeared, nor have they been mentioned, in any installment of the Marvel Cinematic Universe. They remain a concept entirely unique to the comics. The MCU has its own pantheon of ancient cosmic beings, most notably the Celestials, who were central to the plot of the film `Eternals`. In the MCU, the Celestials are depicted as the direct creators of galaxies and sentient life, fulfilling a role that is a composite of their comic book counterpart and elements of the Builders' “cosmic seeder” function. Speculative Adaptation: If the Builders were to be introduced into the MCU, they could be positioned as rivals or a subordinate race to the Celestials. A potential storyline could reveal them as the engineers who built the World Forge (mentioned in `Eternals`) or as an ancient race that rebelled against their Celestial masters. Alternatively, they could be introduced in a future cosmic-level event as a new, extra-galactic threat, perhaps fleeing a crisis in their own universe, mirroring their comic motivation but adapting it for the MCU's ongoing narrative. However, as of now, any discussion of their MCU presence is purely hypothetical.
The Builders' entire existence is defined by their mastery over the physical laws of the universe, a mastery reflected in their biology, technology, and rigid social structure.
The Builders are a humanoid species, typically characterized by their tall, slender frames, elongated heads, and skin tones that range from alabaster white to obsidian black. Their physical forms are merely vessels for their vast cosmic consciousness and power. They are functionally immortal, immune to the ravages of age and conventional disease. While they can be killed by extreme force, their durability is immense, allowing them to survive in the vacuum of space and withstand incredible punishment. Their society is structured around a strict and unwavering caste system, with each caste engineered for a specific purpose.
The Builders' technology is so advanced that it is indistinguishable from magic to most other species. Their power is on a scale that can alter the very fabric of reality.
Builder society is monolithic and totalitarian, governed by a singular, ancient purpose: to impose their definition of order upon the universe. Their ideology, once rooted in creation, became corrupted by a form of cosmic nihilism. They came to believe that the universe's natural tendency towards chaos was a flaw that must be corrected through force. Their march towards Earth during `Infinity` was driven by this philosophy. They had detected the Incursions—the collision of parallel Earths that was causing the decay of the multiverse—and traced the phenomenon's epicenter to Earth-616. In their view, Earth was no longer a beautiful garden but a cancerous weed threatening the entire cosmic ecosystem. Their solution was simple and absolute: to excise the cancer by destroying its source. They believed this act, though brutal, was a necessary sacrifice to save the whole of reality. This unwavering conviction made them impossible to reason with, as they saw their genocidal campaign not as an act of conquest, but as a painful but necessary act of universal preservation.
The Celestials are the only beings in the universe whose age and cosmic significance rival that of the Builders. While not direct enemies for most of history, their relationship is one of cosmic counterparts with differing methodologies. If the Celestials are the gods who dream up reality, the Builders are the titans who give it form. During the `Infinity` event, Captain Universe, speaking with the universe's voice, confirmed this dynamic, stating the Builders went from being the universe's “hands” to a “disease.” The Celestials themselves remained silent during the Builders' final war, their absence a testament to their inscrutable and non-interventionist nature in most galactic affairs. The fundamental question of “who is more powerful, a Builder or a Celestial?” remains a topic of fan debate, though the Celestials' role as fundamental cosmic forces generally places them on a higher tier of the cosmic hierarchy.
The most prominent of the Builders' creations are the Gardeners, Ex Nihilo and Abyss. One such pair was sent to Mars to transform it, preparing the Sol system for the Builders' judgment. This Ex Nihilo encountered the newly expanded roster of the Avengers and, after a conflict, was convinced by Captain America of Earth's worthiness. He began to see the potential in humanity's chaotic nature, a direct contradiction of Builder doctrine. When the Builder fleet arrived, this Ex Nihilo and his partner, Abyss, defied their masters and fought alongside the Avengers to protect Earth, representing a philosophical rebellion from within the Builders' own ranks. Their betrayal was a critical symbolic and tactical victory for the heroes.
The Builders' primary antagonists during the `Infinity` war were the collected empires of the known universe, assembled as the Galactic Council. This alliance was unprecedented, forcing historical enemies to fight side-by-side against a common existential threat. Key members included:
Initially, the Galactic Council's forces were utterly crushed by the Builders' superior technology and tactics. It was only after Captain America took supreme command of the allied fleet that they were able to formulate strategies that could counter the Builders' overwhelming power.
Earth's Mightiest Heroes were the ultimate key to the Builders' defeat. While thanos and his forces attacked a largely defenseless Earth, the core Avengers team was in deep space, leading the galactic war effort. Captain America's strategic genius, Iron Man's technological insights, and thor's raw power were instrumental. It was Thor who struck one of the most significant blows of the war, shattering a Builder with a mighty throw of Mjolnir on the Kree homeworld of Hala, a moment that broadcast across the galaxy and proved to the demoralized allied forces that their gods could, in fact, bleed. The Avengers' refusal to surrender and their ability to inspire hope in species that had long despised humans were the intangible factors that led to the Builders' downfall.
The Builders' entire presence in Marvel comics is almost exclusively contained within a single, massive storyline.
This event is the definitive Builder story, detailing their final, cataclysmic war against the universe.
As a relatively recent and storyline-specific creation, the Builders do not have the extensive history of alternate-reality counterparts that characters like Spider-Man or Captain America do.
Their lack of variants serves to emphasize their unique role in the Earth-616 canon as a singular, ancient force whose story had a definitive beginning, middle, and end, all within one of Marvel's most ambitious modern sagas.
