Maleagant
Maleagant (alternatively Malagant, Meleagan, Meleagant, Meliagant, Meliagaunt, Meliagant, Meliaganz, Meliagrance, Meliagrant, Mellegrans, Mellyagraunce) is an often otherworldly villain from the Arthurian legend. In a popular Arthurian episode recorded in several different versions, Maleagant abducts King Arthur’s wife, Queen Guinevere, necessitating her rescue by Arthur and his knights, later notably Lancelot. The earliest surviving version of this episode names the abductor Melwas in Welsh tales. As Maleagant, he debuts as Lancelot's archenemy in Chrétien de Troyes' French romance Lancelot, the Knight of the Cart, where he is son of King Bagdemagus.
