Gríma Wormtongue, a fictional character by a fictional character in J. R. R. Tolkien's The Lord of the Rings
He is the stereotype of a leader's right-hand advisor who appears loyal but plots against his master — in ways similar to the popular view of Louis XIII of France and Cardinal Richelieu; King Théoden and Gríma Wormtongue; or Goscinny's Caliph Haroun El Poussah and Grand Vizier Iznogoud; or the later Asterix characters Vizier Hoodunnit and Rajah Watzit.
The Epic Story was advanced with Volume 3 Book 4: The Rise of Isengard and introduced such iconic characters as Grimbold, Théodred, Grima Wormtongue and Saruman the White.
