Rick Grimes grew up in King County, where he and Shane became friends and sheriff's-department partners. Husband to Lori and father to Carl, he is a sturdy-built man with short dark-brown hair, a lined face, and hazel eyes; early scenes show his tan deputy uniform. Rick wakes from a coma in Harrison Memorial Hospital and walks abandoned roads toward Atlanta to find his family. His training and empathy guide him, though danger tests both.

Shane Walsh grew up with Rick in King County and became his sheriff's-department partner. A football player and prankster, he knows local roads and people. Broad-shouldered, close-cropped dark-haired, and stubbled, he wears his deputy uniform with easy authority. During the evacuation he gets Lori and Carl out of town, then organizes the quarry camp; his decisiveness can reassure the group or intensify conflict.

Lori grew up in King County, met Rick as a student, and raised Carl at home while her marriage strained. She has long dark-brown hair—not red—fair skin, expressive eyes, and a slender build; in Atlanta she wears practical muted clothes. Believing Rick was left behind, she flees with Carl and Shane. Protective and decisive, she tries to give Carl security while managing grief and divided loyalties.

Carl is Rick and Lori's son, raised in King County with comics, games, and Shane as a trusted family friend. At the Atlanta camp he is a slight, fair-skinned boy with short sandy-brown hair, wide eyes, and a serious expression that gives way to a child's curiosity. He stays close to his parents but wants to understand the adults' decisions. The outbreak forces him to learn caution without erasing his need for play, reassurance, and family.

Glenn is a young Korean American from Michigan who was delivering pizzas in Atlanta when the outbreak began. His short black hair, lean build, quick movements, and easy grin stand out; he favors practical clothes suited to running city streets. He uses alleys, service corridors, and local shortcuts to evade walkers and find supplies. Brave, resourceful, and funny under pressure, Glenn takes risks for people he has only just met.

Daryl grew up in rural northern Georgia with older brother Merle in a neglectful, abusive home. He learned to hunt, track, and fend for himself in the woods. Daryl is wiry and weathered, with shaggy dark-brown hair, stubble, and a guarded stare; he wears worn hunting gear and carries a crossbow. Blunt and wary of strangers, he is most at ease outdoors, where keen observation and practical skills make him valuable to the camp.

Carol Peletier is a mother from the Atlanta area, arriving at Shane's camp with her daughter Sophia and controlling husband Ed. In the first season she is soft-spoken and watchful, with long dark-brown hair usually tied back, a fair face, and a slight build; she wears modest, practical clothes. Cooking, laundry, and tending to Sophia give her familiar work. Beneath her caution is a perceptive woman learning to make decisions for herself and her child.

Maggie Greene is the eldest daughter of Hershel Greene, raised on the family farm outside Senoia, Georgia. She knows the fields, livestock, and routines of rural work, and rides horses with confidence. In the farm era she is a young woman with long dark-brown hair, fair skin, and a practical build, usually dressed for chores. Direct, capable, and deeply loyal to her family, Maggie is willing to challenge her father and strangers alike when their choices put loved ones at risk.

Negan Smith was a high-school gym teacher before the collapse and later became the commanding leader of the Saviors, based at the Sanctuary, a former industrial complex. Tall and broad, with short dark hair, a salt-and-pepper beard, and a black leather jacket, he carries a barbed-wire-wrapped baseball bat he calls Lucille. Charismatic, profane, and theatrical, Negan enforces a rigid tribute system and rules through intimidation, spectacle, and a carefully cultivated image of authority. His profile belongs to the later Virginia era.
