Malachai is the lost sister of Daryl and Merle Dixon. During the start of the apocalypse, she became separated from them. They were never really close, but Daryl was always looking out for her, even when she didn't think he was. He had her back, and made sure that nothing happened to her. Now that she is on her own, armed only with a crossbow, and a few arrows, she must track them down before it is too late. She will stop at nothing, until she is reunited with her family again.
