The duel between Arthur Pendragon and Knight Valiant occurred when Arthur Pendragon and Sir Valiant, both participants of the Tournament of Camelot, were fighting in the last battle of the finale. Valiant had a magical shield, which he had previously used on Sir Ewan and was planning on using against Arthur as well. Since he was not able to prove to the court that Valiant's shield was magical, Merlin learned the animation spell so that he could bring the snakes to life during the battle. Victory: Arthur
