Sir Bedivere was a Knight of Camelot killed by the Questing Beast, when he and Arthur ran back to save Merlin. He was not named until the moment before he was killed off screen (Le Morte d'Arthur).
In the legendsEdit
Sir Bedivere was a Knight of the Round Table. Most notably, he throws Excalibur back to the Lady of the Lake after King Arthur is mortally wounded in his final battle against Mordred.
