Gorbag

According to the original LotR text, Gorbag was a captain of Orcs from Minas-Morgul. He and his charges were the ones who first spotted the unconscious Frodo and carried him into the tower of Cirith Ungol. Later Gorbag was killed by Shagrat, another Orc, in a fierce row over the captive and his mithril mail.

In the movie, Gorbag takes Shagrat’s place as the captain of Cirith Ungol, and is eventually killed by Sam.
