A person who goes through a lot of pain and suffering in life which drives him insane. Hellwalkers are very secretive and cut the people they love right out of their life, they only believe in getting laid and/ or doing drugs. They are also known to be exceptionally hot and sometimes have a deep cynical tone.
P.S. - They are beasts at fighting, they have either extreme strength or a blade of some sort that they are very good with
