Black Stripe was a wolf who was among the forces taken over by Solus after the death of Redeye Garlackson. His true name is unknown, with the nickname "Black Stripe" being applied to him by Jo Shanks.
Black Stripe and several of his compatriots come across Jo Shanks after he was tied up as part of a ruse by his fellow rabbits. Though Black Stripe knows Solus would reward them for turning over the captive, he also likes the idea of killing and eating Jo. When Jo claims he has been left there by several other rabbits as a traitor, Black Stripe demands to know where they have gone.
Black Stripe sends several of his wolves in the direction Jo indicates, but remains behind with a handful. One of them, an archer named Bant, recognizes Jo as a hero of the Battle for Cloud Mountain. Sensing that the rabbit has been lying to them, Black Stripe prepares to attack, only for Jo's friends to spring their trap. Jo is hauled to safety, and manages to shoot both Black Stripe and Bant in the process.
