The central character of the film District 9, Wikus Van der Merwe, a white, South African male, begins the narrative as a representative of the powerful multinational munitions corporation (MNU). His role is to systematically relocate an entire ‘district’ of an alien species that, after mysteriously stranding itself on Earth, had been forced by the South African government into a ghetto. After an accident during a routine trip to serve an eviction notice Wikus is exposed to an alien chemical that causes his body to react violently. Throughout the course of the film the chemical causes Wikus’s body to gradually transform into the alien species. As an alien-human hybrid Wikus’s body becomes a precious commodity to MNU and an unlikely ally to the alien Wikus was serving an eviction to when he was exposed to the chemical. After aiding the alien, named “Christopher”, in an escape from Earth, Wikus is left stranded, wholly alien, ostracized from his wife and all of human society, and awaiting Christopher’s return in order to be ‘cured’.
Wikus is not a sympathetic protagonist. He is portrayed as a banal bureaucrat that shows little compassion to the impoverished aliens he is charged with relocating. The pseudo-documentary style of the film adds to the banal realism of Wikus as a white-collar corporate lackey who does not hesitate to leverage his authority over the marginalized aliens. He demonstrates a kind of working field knowledge of ‘prawn’, a derogatory term for the otherwise unnamed alien species, behavior and family structure. In utilizing his knowledge of the alien species as a means of controlling them, Wikus functions allegorically as an orientalist British colonial official. Thus, he begins the film in a place of authority, and he executes the duty assigned to him with calculated disdain and apathy toward the subjects at his mercy.
After finding a suspicious canister during an invasive home inspection, Wikus is exposed to a black substance that makes him immediately ill. Throughout the rest of the day he becomes increasingly sick and one of his hands begins to mutate. Wikus tries to hide his condition from his wife and coworkers but it is soon discovered that Wikus’s body is merging with alien DNA. His liminal biological status makes his body a valuable commodity to MNU, whose ultimate goal is to utilize the powerful alien weaponry that is somehow tied to alien biology in such a way that humans cannot normally interact with it. Wikus, however, can now use this technology, and MNU decides to dissect Wikus alive in order to hopefully harness his unique biological capability to interact with alien weaponry. Thus, due to his ‘mixed’ status Wikus becomes a helpless subject of the same powerful corporation he was once employed by.
Wikus escapes from the operating table and becomes a fugitive. As a massive liability to the company, Wikus must be contained. To slander his reputation Wikus is portrayed in the media as having sexual intercourse with the alien species that caused him to be “contaminated with an alien disease”. This portrays Wikus as bringing about his own medical condition due to his own supposedly depraved behavior, as opposed to him being merely a victim of circumstance. Public opinion is turned against him, and having no means by which to explain himself and expose MNU, he becomes a social pariah and out of desperation he flees to ‘District 9’ for shelter.
Ironically, Wikus becomes more sympathetic the more he becomes alien. Near the films conclusion Wikus is confronted by a former associate who calls Wikus a “Half-breed piece of shit” as he is about to shoot him. Wikus is saved by a group of aliens who tear the other man armed man apart and leave Wikus unscathed. The film ends ambiguously: Christopher escapes earth but a lone alien, presumably Wikus, is assumed dead by his friends and left to fend for himself.
