The zombie apocalypse

Sara is a female ex-soldier with combat and survival experience as well as the leader of the group of survivors. In her mid-thirties, she has become the natural leader of the group thanks to her ability to make quick decisions and her tactical knowledge. She is strong, determined and knows how to stay calm in critical situations. However, the pressure of leadership weighs on her, and at night she faces an internal struggle for the lives she has failed to save.
Strong and muscular, his skin is tanned by constant exposure to the sun. He has dark brown hair, cut to shoulder length, and usually worn in a ponytail. His green eyes are hard and calculating, with visible scars on his arms and face, the result of old battles. He wears worn military clothing, with tactical vests, combat boots, and a belt where he carries knives and firearms. His posture is upright and confident, showing his military training.

Miguel is a doctor in his forties, a key member of the group. Before the apocalypse, he worked in the emergency room, which has given him the reflexes necessary to treat wounds quickly and on the fly. Although he can be cynical and distant at times, his priority is to keep the group alive. He has to deal with shortages of medical supplies and sometimes has to make difficult decisions, such as amputations or choosing who has the best chance of survival.
He is of medium build, with graying black hair that is somewhat disheveled due to a lack of time to take care of himself. He wears glasses, but they are often broken or patched, a reflection of the hardships of the post-apocalyptic world. His face shows signs of fatigue, with pronounced dark circles under his eyes and a serious expression. He usually wears a worn leather jacket over a button-down shirt and sturdy pants, and always carries a small first-aid kit with the essentials for treating wounds.

Lucia, in her mid-twenties, is a woman and was a civil engineer before the apocalypse. She has proven invaluable to the group thanks to her ability to improvise technological solutions. From building rudimentary traps to repairing vehicles, Lucia is a creative and curious individual. She has an optimistic nature, making her a ray of light in the midst of chaos, though she can sometimes be reckless, putting the group at risk.
Agile and thin in appearance, Lucia has short, messy hair dyed in a blue shade that has begun to fade, revealing her black roots. She often has greasy stains on her hands and clothes, the result of her constant work with machines and improvised devices. She wears a tank top, cargo pants with multiple pockets full of tools, and worn but functional boots. Her brown eyes are always alert, looking for a way to improve something or repair something that needs to be fixed.

Marcos is a man in his fifties, who used to be a ranger at a nature reserve. He has extensive knowledge of hunting, tracking, and survival in the wild. He is in charge of getting food for the group and teaching them how to move stealthily in difficult terrain. Quiet and reserved, Marcos prefers solitude, but has developed a strong bond with Sara, the leader, as they share the burden of protecting the group.
Tall and robust, his skin weathered by years of being outdoors, his face shows scars and a straggly graying beard. His gray hair is shaggy, and he wears a wide-brimmed hat that protects him from the sun. He wears camouflage clothing, with a vest full of knives, ropes, and other hunting implements. His grayish-blue eyes reflect experience and a dangerous calm, always scanning the surroundings for threats. He carries a bow on his back and a machete at his side.

Diego is a 17-year-old boy who has had to grow up quickly after the fall of the world. Before the apocalypse, he was a student who dreamed of being a pilot, but now he faces the brutal reality of the new world. Although he lacks the practical skills of the others, he is agile, brave, and is frequently sent on exploration missions or to retrieve supplies. Being at a vulnerable age, he struggles to find his place in the group, but always proves that he should not be underestimated.
Tall and thin, with long, light brown hair that is usually dirty and unkempt. His dark eyes reflect the fear and hardship he has had to face in this new world. He wears light, worn-out clothing, such as rock band t-shirts, torn jeans, and dirty sneakers. He always carries a worn-out backpack, loaded with personal items, a flashlight, and some provisions.

Hector is the most problematic member of the group. A man in his thirties, before the apocalypse he was an ex-convict. His experience in the criminal world has given him useful skills, such as lock-picking and hand-to-hand combat. However, his distrustful and solitary nature often puts the group's cohesion at risk. He distrusts new people they meet along the way and has constant friction with Miguel and Lucía, although Sara is confident that her experience will be key to survival.
Muscularly built, he has an intimidating appearance. His skin is dark and his black hair is shaved close to the skin. His face shows several scars and tattoos on his neck and arms, some of them depicting his former life in prison. His dark eyes are always alert, and his expression is tense, rarely smiling or relaxing. He wears a tight black T-shirt, torn leather jacket, and worn jeans. He always carries a metal bat or bar, and a concealed pistol.

Elena, in her forties, is a woman who has lost her family in the chaos of the apocalypse. Elena has become the mother figure of the group, worrying about their emotional well-being and trying to maintain humanity in the midst of brutality. She is often the one who makes decisions based on morality and ethics, which causes tensions with the rest.
Of medium build, her face reflects the exhaustion of months of surviving in this world, but she maintains a warm and comforting expression. She has light brown hair, tied back in a messy bun. Her eyes are brown, showing constant concern for the group, especially the younger ones. She wears thick sweaters or jackets and comfortable pants, with a scarf or bandana around her neck. She usually carries a bag in which she keeps basic supplies, such as water and food, always ready to take care of others.

A strange virus, discovered in a remote tropical region, began to spread rapidly around the world. At first, it only affected local wildlife, causing violent and aggressive behavior in infected animals. Intrigued and concerned, scientists attempted to contain the situation, but their curiosity led them to make a fatal mistake: one of the researchers was bitten by an infected creature during a study. What at first seemed like a simple fever quickly turned into a violent transformation. The scientist began to lose control of his motor and cognitive functions, while his most primal instincts took over. His eyes became dull and his skin began to decompose within days.

Before he could be quarantined, the researcher had already infected several lab colleagues, who unwittingly carried the virus outside the facility. Being highly contagious and spread through bodily fluids, within days the virus spread across the city, infecting thousands. Chaos erupted as authorities attempted to contain the situation without success. Panic spread faster than the infection, and the governments of the world were helpless against the onslaught of the undead devouring the living.

The collapse of infrastructure was swift and relentless. Caught between fear and confusion, humanity realized too late that it was not prepared to face a threat of this magnitude. Survivors, hiding in small shelters, watched from the shadows as the world they knew crumbled, and civilization plunged into the darkness of a zombie apocalypse from which they might never be able to escape.
