MHA Apocalypse

MHA Apocalypse - Ever wonder what happens when a human creates a superweapon to fight a hero? A monster-

Since the collapse of society, the world has come to know the creatures responsible for humanity's downfall as Shadow Walkers. Originally created by the mad scientist Garaki as a weapon meant to eliminate powerful heroes, the experiment quickly spiraled beyond anyone's control. Built from modified human tissue, Nomu research, and a biological agent designed to seek out the Quirk Factor itself, the first Shadow Walker escaped containment and began spreading the infection. Within months, entire cities fell. Within a year, nearly seventy percent of the global population had either been devoured or transformed. The event became known as The Black Fall, marking the end of hero society and the beginning of humanity's desperate fight for survival. What makes Shadow Walkers so terrifying is not merely their strength or regenerative abilities, but their ability to detect the presence of a person's Quirk Factor. Every human possesses a unique biological signature connected to their quirk. Shadow Walkers are capable of smelling that signature from miles away. When a person activates their quirk, that scent becomes dramatically stronger, acting like a beacon that can draw hordes of Walkers from across an entire city. Even after a quirk is used, the scent lingers on the body for up to a week, regardless of how thoroughly a person attempts to clean themselves. Because of this, the use of quirks has become strictly forbidden within survivor settlements. To use a quirk is considered an act of recklessness that could condemn an entire community to death. The infection itself spreads through bites, scratches, saliva, blood contamination, or the ingestion of infected tissue. Victims initially suffer from fever, blackened veins beneath their skin, heightened senses, and an overwhelming sense of hunger. As the infection progresses, ordinary food becomes less satisfying, causing many victims to seek out raw meat in an attempt to satisfy cravings that can never truly be filled. Within a matter of days, the infected individual dies completely. Their heart stops, brain activity ceases, and for a brief period they are clinically dead. Then the body rises once more. Every memory, emotion, and piece of humanity is gone, replaced by an endless hunger to consume the living. Newly transformed Shadow Walkers are mindless predators. They cannot speak, reason, or communicate beyond primitive instincts. They are unnaturally silent when moving, their footsteps producing almost no sound. The only noise they regularly make is a series of clicking sounds produced with their tongues. These clicks allow them to communicate basic information to one another while hunting. Fresh Walkers are little more than savage animals driven by hunger, but the longer they survive, the more dangerous they become. As Shadow Walkers age, black patches begin spreading across their skin. At first these patches appear random, but over time they consume the entire body. Their flesh darkens until they appear almost completely black, blending naturally into shadows and darkness. After surviving for roughly a year, a Shadow Walker undergoes another transformation and becomes what survivors call an Elder Walker. These creatures possess glowing golden eyes and display signs of genuine intelligence. Elder Walkers can organize hunting packs, coordinate ambushes, identify weaknesses in fortifications, and deliberately herd prey into traps. Unlike younger Walkers, Elders are capable of patience and strategy, often stalking settlements for days or weeks before attacking. The longer an Elder survives, the more dangerous it becomes. Some settlements tell stories of ancient Walkers that have survived for years. These creatures, known as Sovereigns, possess intelligence rivaling humans. They are capable of planning complex attacks, manipulating the movement of other Walker packs, and studying human behavior. Entire settlements have disappeared after attracting the attention of a Sovereign. Many survivors believe these ancient monsters still possess fragments of the people they once were, making them even more dangerous than ordinary Walkers. One of the most horrifying discoveries made during the apocalypse is that Shadow Walkers do not merely consume humans. They consume Quirk Factors. While most Walkers cannot use quirks themselves, prolonged exposure to specific types of Quirk Factors can cause mutations. These mutated Walkers are known as Aberrants. Some develop bodies capable of generating heat after feeding on large numbers of fire users, while others become massive hulking beasts after devouring strength-based quirk users. Particularly feared are Shade Walkers, whose bodies become almost indistinguishable from natural shadows, allowing them to hide in plain sight for days before striking. Every Aberrant is unique, making them nearly impossible to predict. The collapse of hero society happened with terrifying speed. Heroes were among the first to die. Their powerful quirks acted like massive beacons that attracted overwhelming numbers of Shadow Walkers. Entire rescue missions ended in disaster when heroes unknowingly led hordes directly to evacuation centers. Many of the world's strongest heroes fell during the first year of the outbreak, overwhelmed by enemies specifically designed to hunt people like them. Public trust in heroes vanished alongside civilization itself. Hero licenses became meaningless. The distinction between hero, villain, and civilian disappeared. Everyone became a survivor. One of the largest remaining safe havens is U.A. High School. The campus has been transformed into a heavily fortified stronghold protected by reinforced walls, underground tunnels, watchtowers, and carefully controlled living quarters. Quirk use is strictly regulated within the walls, permitted only during absolute emergencies. Supplies are rationed, patrols constantly monitor the surrounding area, and every resident understands the importance of remaining silent. Ironically, some of the most valuable survival skills came not from professional heroes, but from individuals like Aizawa, whose emphasis on stealth, observation, and efficiency became the foundation of life after the apocalypse. The League of Villains survived for reasons many consider darkly ironic. Long before society collapsed, villains already operated in secrecy, utilizing hidden bases, underground networks, and covert methods of movement. When the outbreak began, Kurogiri managed to transport many members of the League into an underground bunker where they remained hidden during the worst stages of the initial catastrophe. Over time, the League evolved into something entirely different. They are no longer villains seeking to overthrow society. With society already destroyed, they have become survivors like everyone else. Perhaps the greatest tragedy of the Black Fall is the generation born afterward. Children who grow up in the ruins of the old world are taught from birth that quirks are dangerous. Many never learn to use their abilities. Some parents actively suppress their children's quirks, terrified that a single accident could attract death to their doorstep. Young quirk users often grow up fearing their own powers, viewing them not as gifts but as curses. Entire communities have formed around the belief that humanity's dependence on quirks led directly to the apocalypse. For the first time in history, being quirkless is often considered safer than being gifted. Among survivors, one rumor refuses to die. It is said that the original Shadow Walker still exists somewhere in the world. The very first creature Garaki created. Older than every Elder, stronger than every Sovereign, and intelligent beyond anything humanity has encountered. Survivors call it The First Hunger. Unlike ordinary Walkers, this creature is rumored to remember who it once was. Entire settlements have vanished after reports of its presence, and whenever sightings occur, Elder Walkers from across entire regions begin moving toward the same destination. No one knows what it is searching for. They only know that wherever it goes, death follows.

Shadow Walkers are creatures that look like the remains of humanity twisted into something far more dangerous. They are not typical undead creatures that slowly decay; they are engineered predators created to hunt, survive, and evolve. Their bodies still hold a humanoid shape, but every part of them has been altered to make them better at tracking, killing, and consuming. The longer they exist, the less human they become. A newly transformed Shadow Walker still carries traces of the person it once was. Their body remains recognizable, with a human frame, arms, legs, and a face that may still resemble their former self. However, something about them is immediately wrong. Their skin becomes pale and corpse-like, dark veins spread beneath the surface, and their eyes lose all emotion, becoming empty and animalistic. Their teeth sharpen into jagged points, their jaw becomes slightly wider than normal, and their fingers elongate into claw-like weapons capable of tearing through flesh and weak materials. They move with unnatural silence, no longer walking like a person but like a predator stalking its prey. The first stage of their physical transformation begins with the appearance of black patches across their body. These markings usually begin around the hands, arms, neck, or face, spreading outward like an infection consuming the skin. The darkness is not decay, but the Shadow Walker mutation adapting their body. Their skin gradually becomes harder and more durable, creating a natural armor that protects them from attacks. The longer a Walker survives, the more these black markings spread until their entire body is consumed by darkness. As the transformation progresses, Shadow Walkers become increasingly difficult to detect. Their skin absorbs light, making them blend into dark environments and shadows. A Walker hiding inside an abandoned building or forest can become nearly invisible, waiting perfectly still until something living comes close enough to attack. This ability makes them incredibly dangerous because survivors are often not aware they are being hunted until it is already too late. Their bodies are built for speed and strength rather than appearance. Shadow Walkers are unnaturally lean, with elongated limbs, sharp shoulders, and powerful muscles hidden beneath their darkened skin. Their arms and fingers stretch slightly longer than a human’s, giving them a wider attack range. Their movements are unpredictable; they can stand completely motionless for hours, crawl through tight spaces, climb surfaces, and move without making any footsteps. The only indication of their presence is often the faint clicking sound they make with their tongues. Their mouths are one of their most disturbing features. When calm, they may appear almost human, but when attacking, their jaws open far wider than a normal person's should be. Their teeth become sharper and more numerous, allowing them to tear through victims quickly. The clicking sounds they create are used as a form of communication. Younger Walkers use these sounds instinctively, but older ones develop patterns and use them to coordinate attacks. After roughly a year of survival, a Shadow Walker evolves into an Elder Walker. At this stage, their body has fully adapted to the mutation. Their skin becomes completely pitch black, almost resembling living shadow, and their eyes develop a glowing golden appearance. Their bodies become taller, thinner, and more controlled, losing nearly all remaining signs of humanity. Unlike younger Walkers, Elders no longer behave like mindless beasts. They are patient hunters capable of planning, organizing groups, setting traps, and studying their prey. An Elder Walker is less like a monster and more like a predator wearing the shape of a human. Their black bodies blend into darkness, their golden eyes are visible even in complete darkness, and their movements are deliberate and calculated. They no longer rush blindly toward prey. They observe. They wait. They learn. Survivors fear Elders because they are proof that Shadow Walkers are not simply creatures of hunger, they are creatures capable of becoming something worse. The oldest and rarest Shadow Walkers, known by survivors as Sovereigns, are believed to be the ultimate result of Garaki’s creation. These beings have existed long enough to evolve beyond what anyone thought possible. Their bodies are completely adapted for hunting, their intelligence rivals humans, and they are capable of controlling other Walkers around them. Some survivors believe Sovereigns still contain fragments of their original minds, making them even more terrifying because they may remember what they once were. The most frightening thing about Shadow Walkers is not their appearance. It is the fact that underneath all the darkness and mutation, there are still small traces of what they used to be. A familiar shape. A familiar face. A reminder that every monster was once human before the hunger took over.

Not saying I creeped the out of myself writing this. But I absolutely did.
