Eliza Morales is a survivor of the outbreak in AMC's The Walking Dead. During the initial outbreak, she, her father, her mother, and her brother escaped from Atlanta. They eventually find a camp of survivors and stay there. After the camp was overrun one night, the Morales family left for Birmingham, Alabama.
Almost nothing is known about Eliza's life prior to the outbreak; she may have been living in the city of Atlanta during her lifetime along with her family and brother.
Eliza is seen playing around with her brother, Louis. At the camp with her brother and mother, she awaits her father's return from doing a supply run in Atlanta with some other survivors. When he returns, she, with her brother, and her mother give him a big hug.
While enjoying the fish feast with her family and other survivors, zombies attack the camp, prompting her to flee to her parents and to the RV while the others try to defend the women and children. She and her family survive the attack.
Having survived the attack, she attends the funeral for the fallen survivors. While the group decides to head for the CDC, her parents spoke up, saying that they decided they are going to take their chances and head for Birmingham, Alabama, since they have family that may be alive in the area. She says goodbye to a tearful Sophia Peletier and gives her her doll. She parts ways with her family as everyone leaves camp.
It's mentioned that Morales' whole family was killed. It's not known how Eliza died.
Eliza loves her father very much. This is shown when Morales returned from Atlanta, Eliza was overjoyed, and quickly ran into her fathers arms hugging him tightly.
Miranda and her daughter seemed to have a stable mother-daughter relationship. Not much was shown of the two together.
Louis and Eliza have a basic brother-sister relationship and were usually seen talking and playing together.

Sophia often played with Eliza, her brother Louis, and Carl in the camp and it can be inferred that they became close. When Morales and his family leave the camp to search for their relatives in Alabama, Eliza and Sophia share a brief yet tearful goodbye. Eliza hugs Sophia goodbye, and even gives Sophia her doll as a parting gift between friends.
