Ripper was a male rat, a member of Plugg Firetail's crew. He didn't have a tail at all, he had only one eye and he was missing half an ear. He accompanied Slitfang on the expedition which later led to the capture of Scarum, Sagaxus and Kroova, and was sent back along with Scummy and Tazzin to bring the news to Plugg. He was part of the ill-fated gang that attempted to burn down the maingates of Redwall Abbey. He showed a dislike for Princess Kurda at two occasions; once onboard the Seascab when he openly refused an order from her, and once in a secret conversation with Tazzin. Ripper was a minor character, nothing else is known about him.
