Jasperre le Beau
Jasperre le Beau is one of the fairly large assortment of special characters for Bretonnia that appeared only in Warhammer 5th edition and were subsequently removed when it received its more grimdark revamp in 6th edition.
Also known as, simply, "The Dragonslayer", Jasperre is the greatest expert in killing dragons to be found in all of Bretonnia. Something ably assisted by his pegasus steed. He still bears a protective talisman made from the claw of Malgrimace, a dragon he slew for attempting to kidnap Princess Isabeau, daughter of King Louen Leoncoeur.
