Ewan

Ewain was a knight in Albion who fought in the Tournament in Camelot.

He won several duels before facing Valiant, who invoked the snakes on a magical shield to attack Ewain and defeat the knight. Ewain was treated for his injury by Camelot's court-physician Gaius and Gaius's apprentice Merlin, who discovered the true nature of Valiant's shield and decapitated one of the snakes. With the snake's head, Gaius was able to brew an antidote to the snake's venom, and Ewain as on the road to recovery when he was subsequently attacked by another of the shield-snakes and killed before he could testify before the King.
