Bolg
From the One Wiki to Rule Them All, the Lord of the Rings Encyclopedia.
Bolg was an goblin chieftain, the son of Azog, who came to power in Moria after Azog was killed in the war with Dwarves.
Bolg ruled Moria for some 150 years and led the army of goblins in the Battle of Five Armies, in which he took his bodyguards with him. In that battle, his head was crushed by the mighty Beorn after killing Thorin.
