You see Luis was not a strong boy as you thought. In fact he was always bullied for that. One day he decided he's leaving the village to look for a better place. As he started walking, he eventually met a group of zombies. He knew he wasn't a match for the zombies so he fleed.

Not knowing he was heading directly to a monstrous wolf's cave. As he entered it was dark and quite too quiet. He thought of something watching him. Just as he was about to leave, the wolf came out so mad. As Luis so it he was frightened. He has never seen such a beast before. He thought of it as a companion for his adventures. As he tried to tame it. The horde of zombies appered. They had no other choice but to fight with thee zombies. As they finished the beast took Luis as his owner.
