Gizotso is a savage monster that lives in the deep forest and looks like half wolf. He is extremely strong and comes out at night with chains hanging from his body. In Luzaide (Navarre), they are told to be terribly strong and to have to be born from the sexual intercourse between humans and wild animals.
On one occasion, Gizotso was seen in Mont Urkia while he was heading for Aginao’s (a country house in Zeanuri, Biscay); and some villagers shouted a warning to a woman who was near that house: “Run away from there, Gizotso is approaching!” As soon as she heard the shout, she started running home but the savage was quicker. He caught the started woman and disembowelled her.”
