What Alien: Covenant Is and Why It Functions as a Prequel
Alien: Covenant (2017) is a science-fiction horror film directed by Ridley Scott that follows the colonization ship Covenant en route to a remote planet, only to encounter a derelict structure and a lone survivor from a prior mission. Released eight years after Prometheus and more than thirty years after Alien, it occupies a middle timeline in the larger saga while also extending the mythology of the Engineers and the origins of the Xenomorph. The movie explores themes of creation, belief, and biological hazard, integrating religious imagery and biomechanical design that echo the original while deepening the overarching questions about humanity’s creators.
Chronological Position of Covenant in the Alien Franchise
Placement Between Prometheus and the Original Film
In the expanded chronology, Alien: Covenant occurs after Prometheus (2012) and well before the events of the 1979 film Alien. Its timeline can be summarized as follows.
| Title | Year | Relationship to Covenant |
|---|---|---|
| Prometheus | 2093–2094 | Direct prequel; establishes the Engineers, Planet 4, and the mutagenic threat. |
| Alien: Covenant | 2104 | Settler ship diverted to an uncharted world; connects Prometheus discoveries to the derelict found by the Nostromo. |
| Alien | 2122 | Sequel; the Nostromo encounters the derelict and crew member Kane is infected, leading to the Xenomorph outbreak. |
| Aliens | 2179 | Sequel set two decades after Alien; Colonial Marines respond to the loss of contact with Gateway Station and LV-426. |
By the time the colony ship arrives at the planet that will become LV-426, the events of Prometheus have already seeded the biosphere with Engineer technology and the Black Goo, making Covenant a narrative and evolutionary bridge between the ancient Engineers and the Xenomorph threat introduced in Alien.
Key Characters and Cast in Covenant
The film centers on the crew of the colonization vessel Covenant, who awaken from hypersleep earlier than planned. The protagonist is Walter One, an advanced synthetic played by Michael Fassbender, who serves as the android counterpart to the character David from Prometheus. Katherine Waterston leads as Daniels, the first officer, with Billy Crudup as the ship’s captain, Oram. Additional cast members include Demián Bichir, Jussie Smollett, and Carmen Ejogo. The supporting presence of David, portrayed again by Fassbender, ties the narrative directly to Prometheus and complicates the moral landscape of both films.
Thematic and Narrative Links to Prometheus
Questions of Creation and Hubris
Both Prometheus and Alien: Covenant explore humanity’s pursuit of its creators and the dangers of unchecked scientific ambition. In Prometheus, the crew seeks the Engineers; in Covenant, the settlers chase a new beginning while carrying synthetic life that questions the nature of humanity. Walter and David embody different philosophies of artificial life, and their interactions underscore themes of responsibility, control, and the ethics of creation. The recurring imagery of gestation, birth, and biological experimentation reinforces the idea that knowledge can be as lethal as it is empowering.
Religious and Symbolic Motifs
Ridley Scott continues to frame the saga with religious symbolism, from the Engineer crucifixion in Prometheus to the chapel and hymn sequences in Covenant. The planet’s valley, with its carved stone heads and temple, evokes a cathedral of destructive worship, positioning the Xenomorph as both punishment and offspring. Characters frequently invoke faith and destiny, only to confront the indifference or hostility of the biological and cosmic order they sought to understand.
Worldbuilding and Biomechanical Aesthetics
The design language of Covenant remains rooted in the series’ blend of organic and industrial elements. The derelict ship, with its skeletal curves and biomechanical corridors, connects visually and conceptually to the structure beneath the Engineer pyramid in Prometheus. Xenomorph design is refined here, emphasizing speed, stealth, and a nightmarical alignment with human anatomy. These aesthetic choices reinforce the idea that the Xenomorph is both an evolutionary weapon and a perversion of natural life, engineered to ensure its own propagation through devastation.

Covenant’s Legacy and Series Influence
Alien: Covenant polarised audiences but solidified the idea of the prequel as an essential, ongoing layer of the franchise rather than a standalone detour. Its exploration of synthetic consciousness, colonial ambition, and biological horror can be traced forward into subsequent projects, including the TV series Alien: Romulus (2024), which further treats the expanded universe as a mutable, interconnected space. The film reshapes audience expectations of where and how the Xenomorph story can begin, inviting viewers to consider the broader implications of humanity’s reach beyond Earth.
Conclusion: Covenant as a Necessary Prequel Link
Alien: Covenant functions as a deliberate prequel that deepens the mysteries introduced in Prometheus and retroactively enriches the stakes of the original Alien. By positioning itself between the arrival of the Engineers on Planet 4 and the Nostromo’s doomed landing on LV-426, it provides narrative continuity, visual continuity, and thematic resonance. For viewers, understanding Covenant as a prequel illuminates the series’ persistent questions about creation, control, and what it means to be human in the face of unknowable cosmic forces.
