It has been hard for me to gain information on the Navajo Skinwalker as many native American tribe members refuse to talk about it out of fear. They often believe skinwalkers live amongst the tribe and transform during night. A skinwalker is a man who after doing some immensely evil deeds has gained powers which allow them to transform into an animal or person. One of these evil deeds include killing a close family member.
Skinwalkers are evil by nature and will try to inflict harm. Skinwalkers are known to do small things such as banging on walls, running on roofs and smashing windows to scare people but more typically will try to kill people for fun or food.
