Bard

Bard the Bowman is a character in J. R. R. Tolkien's The Hobbit. A Man of Laketown and a descendant of the ancient Lords of Dale, Bard manages to kill Smaug, the dragon, after which he becomes king of Dale. Tolkien created the character specifically to kill Smaug, since none of the other protagonists of the story were able to fulfill this role. Bard the Bowman could have been inspired by Wiglaf from Anglo-Saxon poem Beowulf.
