Skipper was a male otter leader of Mossflower Woods. He was directly descended from the Taggerung, Rillflag, Filorn, and Deyna I, and inherited some of their skills. He was the uncle of Churk and Rumbol.
Skipper rescued Bikkle and Ruggum from serpents with Log-a-Log Groo. He was visited by Martin the Warrior twice in dream sequences, during which he was told to give Martin's sword to Trisscar Swordmaid as well as provided a hint as to how to translate Royal House of Riftgard Script.
He was involved in battles at Brockhall and Riftgard. Abbot Apodemus once invited him to become Champion of Redwall, but he declined and became Master of Arms.
