Sharku

Appearing only in the film adaptation of The Two Towers, Sharku is the Orc leader of Saruman's Warg riders. Sharku means "old man" in the language of Saruman's servants and may be a designation that he is an elder. However, in the book Sharku refers to Saruman himself. It is modifed to "Sharkey" by his minions when they take over the Shire.

In the film, Sharku has a short battle with Aragorn on his Sharku's Warg. The Warg now in a frenzy of fear, gallops towards the ledge of a cliff. Sharku, injured by Aragorn, falls off of the Warg. Aragorn becomes stuck to the Warg's saddle and tumbles to his supposed death. Unable to find Aragorn, Legolas and Gimli threaten and interrogate a dying Sharku who reveals Aragorn's fate before succumbing. He is also seen in The Battle for Middle Earth II and The Lord of the Rings:The Third Age.
