Shagga

From A Wiki of Ice and Fire

Shagga Son of Dolf, is a member of the Stone Crows, one of the clans of Mountains of the Moon. A large man, he has a deep voice and prefers to fight with a weapon in each hand.

After Tyrion Lannister won his trial by combat in the Eyrie, Shagga was in the band of clansmen that first seized him. Shagga agreed to serve Tyrion for pay, and fought at the battle between the Lannisters and the Northmen under Roose Bolton. Later Shagga went with the Imp to King's Landing before being sent to raid in the Kingswood in order to delay Stannis's forces.
