Xu is a 28 year old guy who was bite in the beginning of the outbreak. He didn't really turn into a zombie though, he turned into a hybrid. He thought the same and looked completely the same as he did when he was human, tall with a strong build, dark black hair and a handsome face with stern red eyes. But he didn't need to sleep or eat human food/drinks anymore, he only needed blood, whether it be from humans or animals, he needed it to stay in control of his actions and stay healthy.
