Adam Sutton is a survivor of the outbreak in AMC's The Walking Dead. He is a former member of the Whisperers, but is later abandoned by his mother. He is then rescued by the Hilltop Colony and is adopted by Earl and Tammy Rose Sutton. After Tammy and Earl's death, Alden becomes his parental guardian.
Adam is born nearly 8 years into the zombie apocalypse to a woman who is a member of a group of primitive survivors known as the Whisperers. It is unknown who his father is or if he is still alive.
As Alpha begins a negotiation between the two groups, a small herd begins to approach due to Adam crying. Fearing for her life and not having another choice, Adam's mother decides to abandon him as he cries. Luke and Alden beg for Alpha to spare the helpless infant, but Alpha coldly refuses, claiming that if the mother cannot quieten the child then the dead will, claiming it as being "natural selection". Luke, having seen Connie hiding behind the cornfield, then begins to use ASL to inform her to retrieve the baby.
Connie rescues the baby and runs into the cornfield as they begin to be chased by both walkers and Whisperers alike. After multiple close calls with walkers, both Connie and the baby are eventually saved by Daryl, Kelly, Earl, and Tammy Rose.
After Lydia is given back to Alpha and the Whisperers, the baby is given shelter at Hilltop and is adopted by Tammy Rose and Earl.
The baby is taken with Tammy and Earl to the Kingdom. Tammy cradles the baby in her arms as the elderly couple discuss where a good home for him would be. Suddenly, they are ambushed by the dead, walkers surrounding Tammy and the baby in the wagon. In order to keep the baby safe, Tammy tucks him away into a box with air holes so the walkers can't get to him. Once all the walkers are killed, the baby and the others make it to the Kingdom.
Once at the Kingdom, Tammy confesses to Earl and Nabila that she wants to keep the baby and raise him.
Tammy Rose and Earl walk the baby around the fair (walking by Alpha in disguise who recognizes the baby she almost left to be eaten alive) as they decide on names for their newly adopted son. Tammy suggests Adam, and Earl comments that he knew an Adam when he was younger. Later, Earl carries Adam around as he and Kelly ask Connie if she had seen Tammy Rose. After it was revealed Tammy Rose was among the fair attendees to have been kidnapped and killed by the Whisperers, Earl holds Adam as he listens to Siddiq's story about what had happened.
Adam is remembered by his biological mother as she was forced to leave him behind to be devoured by walkers in a flashback to the time she brought him to the Hilltop in search of Lydia.
Adam sits outside in his stroller parked by the blacksmith as his father works. He coos and babbles as Earl shares his experience in the Vietnam War to Alden. Earl eventually walks over to Adam and kisses him on the head.
Having arrived at Hilltop, Mary attempts to see her nephew, but is repeatedly denied by Earl and Alden, angry at the losses of their loved ones to the Whisperers and how Adam was abandoned in the first place. Inside the Barrington House, Adam is being held by one of the caretakers sitting with Nabila when Mary sees him. As she attempts to approach him, Alden cuts her off, stating that she will never be able to have him, and promptly takes Adam out of the caretaker's arms and walks away with him. Later, Adam is among the children and parents to be evacuated from Hilltop. However, the caravan is prevented from reaching Oceanside after reaching a roadblock consisting of a fallen tree, the doings of the Whisperers. The caravan turns back to Hilltop, along with the bodies of murdered scouts Felix and Penny. That night, he takes refuge inside Hilltop along with the other children and civilians as the coalition soldiers fight against the Whisperers and their horde.
When the Hilltop falls, Adam is rescued by Alden, Kelly and Mary and taken to safety by them. However, the group is unaware that Earl was bitten and subsequently dies, leaving Adam with all of his adopted family gone. Before his death, Earl expresses confidence to Judith that Alden will take care of Adam in his place.
As the group makes their way down the road, Adam becomes fussy and Alden, despite his inability to soothe the baby, refuses Mary's advice on how to handle Adam due to his anger towards her. Mary eventually gets Alden to take her advice and allow her to hold Adam. Mary is able to calm her nephew with Mary's obvious affection for her nephew and vice versa causing Alden to soften his attitude towards Mary. Resting, Mary tells Alden and Kelly that Adam had meant everything to his mother and expresses remorse for killing Frances.
Spotting a herd coming, Mary leads Alden and Kelly to safety in an abandoned van and gives them Adam before locking the group in. Rather than risk the life of Adam, Mary leads the walkers away with a scream and manages to kill them all. However, Mary is brutally killed by Beta and put down by Alden. Following Mary's death and Beta fleeing, Alden and Kelly are left to take care of Adam, mourning Mary's sacrifice.
