The Onceler pairing creates a specific and somewhat surreal dynamic. Fanfiction centered on this duo is necessarily a self-contained, self-referential space, often exploring themes of self-obsession, fractured identity, and darkly comedic narcissism. A classic and widely-used storyline is the classic 'Enemies to Lovers' arc, though here the 'enemies' are mirror images. Writers craft tales where the confident, charismatic corporate Onceler and the guilt-ridden, post-fall Onceler from the film's frame narrative are forced to interact—often through magical means, a time loop, or a dimensional rift. The conflict stems from one being the architect of the other's ruin, leading to intense arguments, physical clashes, and a slow, grudging understanding that morphs into something more intimate. It’s essentially a character wrestling with his own consequences in the most literal way possible, and the romance that emerges is charged with self-loathing and a strange form of self-acceptance.
Another prevalent plot involves the concept of internal duality externalized. Stories might feature a 'Split' or 'Jekyll and Hyde' scenario, where the Onceler’s public persona and private conscience manifest as two separate physical beings. The slick, greedy businessman and the anxious, artistic inventor who loved making musical instruments become distinct entities locked in a symbiotic and often toxic relationship. These narratives dive deep into psychological horror and dependency, exploring questions of which version is the 'real' one and whether they can exist apart. The romantic tension is inextricable from the existential crisis, creating a storyline that feels both claustrophobic and compelling.
More lighthearted, though still meta, approaches include 'Corporate Rivals' or 'Business Partners' AUs. Here, both Oncelers are separate individuals in a modern setting—perhaps rival CEOs or reluctant co-founders of a startup. The comedy stems from their identical looks causing mistaken identity scenarios, or their clashing business philosophies (one ruthlessly expansionist, the other leaning toward sustainability) leading to boardroom showdowns that eventually turn into something else. These stories strip away the canonical environmental allegory and focus purely on the tension between two facets of the same archetype, allowing for classic rom-com tropes to play out in a uniquely bizarre context. The appeal lies in seeing these characters we know as one person navigate a world where they are two, trying to figure out why they feel such a powerful, unsettling connection to someone who feels like a reflection.
A final, more niche but haunting storyline involves 'After the End' narratives. The fic starts after the original story concludes, with the lonely, repentant Onceler in his tower. Through a magical artifact, a dream, or a mental breakdown, he conjures a phantom companion—a vision of his former self. This leads to a series of conversations, arguments, and melancholic encounters where he must confront his past literally, often leading to a tragic or bittersweet romance with a ghost of his own making. It’s less about external adventure and more about a solitary character’s journey through regret and madness, with the romantic element serving as a manifestation of his unresolved guilt and lingering narcissism, which I always find to be a uniquely poignant take on the pairing.
