Bigfang was a burly Terramort searat and a member of Greypatch's crew. Rebellious and sullen, Bigfang disliked Greypatch and often challenged his authority as their ship, the Darkqueen, crossed the sea. After they landed at Mossflower Woods, Greypatch learned of Redwall Abbey and was determined to occupy it. His first aggressions towards the Abbey resulted in humiliating defeat.
