Goblok

Goblok was an Orc chieftain from the Misty Mountains in the service of Khamûl. He and his troop were sent to capture the creature Gollum, whom the Dark Lord Sauron was seeking to use as a means to retrieve his One Ring. His unusual height and strength (possibly due to rumored Troll-blood) intimidated his underlings into submission, much like he feared his own lord.

History
An Orc chieftain from the Misty Mountains, Goblok and his troop were gathered by Khamûl the Black Easterling to Dol Guldur in preparation for war. His unwavering allegiance and fear of the dread-lord as well as his own underlings' fear of him led to his rise through the ranks, becoming second only to the Dark Marshal himself.

At the command of the Dark Lord Sauron, Goblok's troop of Orcs was sent to capture the creature Gollum and have him lead them to the possible whereabouts of the One Ring. The chief's fear of the Black Easterling and the Dark Marshal would ensure that should he find the prized possession he would not try to keep it himself.

Little did Sauron know that the heir of Isildur, Aragorn II, had been sent by Gandalf the Grey to capture Gollum and learn what he knows of the Ring. Two Orc scouts sent ahead were killed by the ranger, causing the troop to realize that there was someone else out there on the hunt for the creature. Aided by the Dark Marshal, the Orcs followed Aragorn near the forests of Mirkwood and confronted him. After the soldiery was cut down to the last, Goblok himself faced the ranger and was killed.
