Lancelot is, of course, the premiere knight in the court of King Arthur. On the battlefield, he is almost unbeatable. In his adventures, Lancelot slays all manner of annoying evil knights, and is granted, due to his purity of heart, a vison of the holy grail. What makes Lancelot most interesting, however, is the central role he plays in the fall of Camelot due to his love of Queen Guinevere.
