Hari Sullivan

Hari Sullivan was the name taken on by a yeti who somehow disguised himself as a hippie in an effort to befriend Dr. Who. He was recognised for a yeti by Susan, who threatened him with a hammer and a wooden stake, causing him to run away. (NOTVALID: Doctor Who 3 - The Third Motion Picture)
