Falstaff

Sir John Falstaff is a fictional character who appears in three plays by William Shakespeare. In the two Henry IV plays, he is a companion to Prince Hal, the future King Henry V. A fat, vain, boastful, and cowardly knight, Falstaff leads the apparently wayward Prince Hal into trouble, and is ultimately repudiated after Hal becomes king. Falstaff also appears in The Merry Wives of Windsor.
