Wānana

Wānana is a were-wolf like creature that stands on two massive hind legs with arms that drag behind it. When provoked or surprised, Wānana will attack violently, ripping apart the intruder. Over time this creature will start to trust anyone who visits often and doesn't provoke it making Wānana a trusting companion. After building trust with someone, Wānana will target people who negatively effect said trusted person until the offender is either dead or greatly injured. Wānana is known to have escaped multiple times to carry out it's attacks.
