I. Grayson Cross – "The Survivor" (Main Character, OC)
A. Identity
Mainly known by the moniker "The Survivor," Grayson embodies both the hardened resilience and the tragic vulnerability of those left behind after humanity's near extinction. His name carries the weight of a man who has witnessed too much and still dares to push forward.
B. Backstory & Origins
Grayson was once a military recon operative—a specialist trained in covert operations, survival tactics, and tactical warfare. During the initial outbreak of the virus that decimated humanity, he was part of an elite unit dispatched to monitor and secure quarantined zones. However, when the virus mutated and spiraled beyond control, the extraction mission turned disastrous. Declared KIA by his superiors, Grayson was assumed dead. Yet fate had another plan; he managed to escape, wandering the wastelands as a ghost of his former self.
After years of solitary survival, scavenging for food and relics of the old world, Grayson has become a man defined by loss and determination. The memories of fallen comrades and shattered orders haunt him like phantoms. His every step is measured, not only to survive but to make sense of a world that seems to have forgotten what it means to be human.
C. Personality & Psychological Profile
Grayson is the epitome of a reluctant hero. His military training lends him a calm, analytical approach in the midst of chaos, yet the prolonged isolation and trauma have slowly chipped away at his resolve. There's an inner conflict between his disciplined nature and the creeping madness induced by endless solitude and constant danger.
Resilience: Despite the horror he endures, Grayson's will to survive is unyielding. Every scar, both physical and emotional, is a testament to his determination.
Haunted: Flashbacks of failed missions and lost friends plague him. These memories often merge with the present, making it hard for him to distinguish reality from nightmare.
Resourceful: Having spent years navigating ruined cities and wild wastelands, Grayson is an expert scavenger. He knows how to repurpose old technology, improvise weapons, and set traps for both infected and wild animals.
Morally Complex: While his instincts drive him to survive at any cost, he still clings to remnants of honor and duty. This internal struggle forces him to question whether saving a life is worth the risk in a world where every step could be your last.
D. Appearance & Gear
Grayson's physical appearance is a chronicle of his brutal journey:
Build: Medium height with a lean, muscular frame honed by years of relentless survival. His body is a canvas of scars and weathered skin, each mark telling a story of past battles.
Attire: He wears a patched, military-grade coat layered over tactical gear that has seen better days. The coat is stained with dirt and old blood, and its once-camouflage fabric now appears muted by the ravages of time and exposure. Underneath, he sports a worn, grey shirt and faded cargo pants with multiple pockets—each filled with essential survival tools.
Helmet & Eye Gear: A battered, thermal night-vision helmet sits atop his head. One eye is obscured by a clouded lens, a permanent reminder of the virus's initial assault. The helmet's visor intermittently flickers, revealing glimpses of the ruined landscape.
Weapons: Grayson carries a broken pulse rifle—an old relic that still manages to deliver deadly bursts when needed. A survival knife fashioned from scrap metal is strapped securely to his leg. Additionally, he maintains a small arsenal of improvised gadgets: homemade injection kits designed to slow infection, smoke grenades for diversions, and a multi-tool for repairing or dismantling devices.
Accessories: A red-stained bandage wraps around his wrist—a memento of a fallen comrade and a symbol of the personal cost of his mission. He also clutches an old digital recorder, a device that plays back fragmented audio logs, serving as both a mental anchor and a connection to the world he lost.
E. Narrative Role & Arc
Grayson Cross is not just a survivor; he is the linchpin of the narrative. His journey through Noo-noo Village and beyond serves as the reader's entry point into the devastated world of "Slendytubbies: Red Mercy."
Investigation & Discovery: Drawn by a mysterious distress beacon emanating from the heart of the infected zone, Grayson embarks on a mission to uncover the origins of the virus. His investigative arc is filled with moral dilemmas, where every discovery forces him to question what it means to be human.
Alliance & Conflict: His path will cross with other survivors—like Walten—and his reluctant interactions with the infected, including unexpected, almost surreal encounters with characters like UltSans. These interactions test his resolve and push him to redefine his own humanity.
Transformation: Throughout the story, Grayson undergoes a metamorphosis from a solitary soldier to a reluctant leader. His evolution is driven by both external conflicts and the internal battle against creeping madness. Every victory, every failure, shapes him into a symbol of resistance against the relentless tide of infection.
II. Walten – "The Guardian"A. Identity & Role
Walten, known affectionately among fans as "The Guardian," is a pivotal non-infected character who stands at the crossroads between the old world and the new nightmare. As a white teletubby remnant of a lost age, Walten serves as both a keeper of history and a sentinel against the ever-encroaching darkness. Though physically non-infected, his existence is intertwined with the tragic fate of his kind.
B. Backstory & Origins
Walten witnessed the collapse of the original teletubby world long before the current crisis engulfed humanity. He was once part of a nurturing environment—one filled with laughter, innocence, and a sense of unity. However, as the virus spread and twisted everything into a perverse reflection of its former self, Walten became a lone guardian, burdened with the responsibility of preserving what little remains of that lost era.
Custodian of Memory: Walten's primary role is to document the horrors and the remnants of the original teletubby legacy. Equipped with a sophisticated, night-vision camera, he traverses the desolate landscape, recording evidence of both beauty and atrocity.
Witness to Transformation: Having seen the fall of Po, Laa-Laa, Tinky Winky, and Dipsy, Walten carries an unspoken grief. His eyes have recorded more than any living being should bear, and he struggles under the weight of memories that are as haunting as they are instructive.
C. Personality & Psychological Profile
Stoic & Methodical: Walten is a study in quiet determination. His stoicism is born from necessity—every moment must be preserved and understood if there is any hope of rebuilding. He approaches every encounter with a methodical calm that belies the storm of emotions he battles internally.
Haunted by the Past: Beneath his measured exterior, Walten is tormented by the echoes of what was lost. The memories of the original teletubbies, now warped into monstrous forms, haunt his every step. This burden makes him both a guardian and a prisoner of history.
Empathetic & Cautious: Though hardened by the loss and devastation, Walten possesses a deep empathy for survivors. He often acts as a reluctant advisor to those who cross his path, guiding them with the wisdom of a man who has seen too much but still believes in the possibility of redemption.
Resolute Curiosity: Walten is driven by an unyielding need to understand the infection. His recordings and notes are filled with hypotheses and observations, as he meticulously documents the transformation process of his former kin. This quest for knowledge is both his strength and his curse.
D. Appearance & Gear
Physical Form:Walten retains the eerie, ethereal appearance of a teletubby, though time and loss have taken their toll. His once pristine white form is now marked by faint discolorations and subtle signs of decay, a visual reminder of the world that has passed.
Attire & Equipment:
Camera: The cornerstone of his identity, Walten's high-tech camera is outfitted with night vision, thermal imaging, and audio recording capabilities. It is his primary tool for gathering evidence and serves as a symbolic connection to the lost innocence of the teletubby era.
Outfit: Walten's attire is minimal yet practical—a simple vest and worn trousers that allow him the freedom to move stealthily through ruined landscapes. The colors are muted, emphasizing the stark contrast between what once was and the current desolation.
Visual Details:His eyes, though not as vivid as they once were, retain a glimmer of the light that defined his past. A faint aura of melancholy surrounds him, the result of countless hours spent in the dim glow of monitors and the dark corners of abandoned structures.
E. Narrative Role & Arc
Walten is both a historian and a guide. His role in "Slendytubbies: Red Mercy" is multifaceted:
Keeper of Lost Truths: By documenting the fall of his own kind, Walten provides essential exposition and a visceral account of how the infection transformed the teletubby world. His recordings reveal the stark contrast between the innocent past and the brutal present.
Reluctant Ally: When Grayson Cross and other survivors cross paths with Walten, he becomes a vital source of information. Although initially reserved, his deep empathy compels him to aid those who seek to uncover the truth behind the viral apocalypse.
Moral Compass: In a world where the lines between monster and man have blurred, Walten serves as a reminder of what was lost. His internal conflict—between preserving the past and confronting the inevitable horrors of the present—mirrors the broader theme of the fanfic: the collapse of innocence under the weight of overwhelming despair.
Catalyst for Redemption: Ultimately, Walten's journey is one of reluctant hope. His careful documentation and willingness to share the painful history of the teletubbies become a foundation upon which the survivors can build a new understanding of their world, even if redemption remains a distant dream.
