The Lord of the Rings: War in the North
Tharzog leads Agandaûr's orc and goblin soldiers that have gathered in Fornost, the ancient former kingdom of the Dúnedain and capital of the realm of Arthedain. He is seen at the citadel gathered with other Orcs and goblins. Agandaûr walks in, and asks Tharzog what the disturbance in Fornost is. He tells him that there are intruders who have freed their prisoner Beleram, one of the Great Eagles. Tharzog tells Agandaûr that the intruders must be great warriors, and that they might be elves or Dwarves. Agandaûr tells him furiously that he doesn't care, and that he wants them taken care of now. Tharzog orders one Orc to call his guard. He spots the elf twins Elladan and Elrohir going through the stairs leading to the top of the citadel. The gate closes behind them, cutting off their allies Eradan, Farin and Andriel.
Tharzog battles the trio along with his Orc and goblin guardsmen. Unfortunately, Tharzog cannot overcome the trio's combined strength, and eventually dies.
Tharzog is a large, tall, and muscular Orc. His height reaches to the chest of a troll. He wears heavy armor, carries a large, rusty sword, and his face is covered by a helmet with a skull on the top of it. His eyes are wide and yellow, his skin is muddy dark brown, and he has two fangs over-biting his mouth.
