Kay is often depicted as a proud and arrogant knight who is quick to anger and often engages in quarrels with other knights. He is also known for his loyalty to King Arthur and his willingness to fight for him, even when it means putting his own life at risk.
In some versions of the Arthurian legend, Kay is said to have been the original wielder of the sword Excalibur before it was given to King Arthur. In other versions, he is the one who helps Arthur retrieve the sword from the Lady of the Lake.
The character of Kay has been featured in numerous works of literature, art, and film, including the works of Sir Thomas Malory, Alfred, Lord Tennyson, and John Steinbeck. He is often portrayed as a complex and contradictory character who embodies both the virtues and flaws of chivalry.
