Bolg

Bolg was the son of Azog. Bolg was presumably born at the end of the War of the Dwarves and Orcs. He later grew up to be as ruthless as his father, and participated in the Battle of the Five Armies. He later met his foul end by Legolas's hand being killed by one of his daggers.
== Biography ==
Azog is summoned to Dol Guldur to become the commander of Sauron's orc armies. While there, Azog dispatches his son Bolg to take his place in hunting Thorin and his company. With his pack of Orcs, Bolg tracks Thorin and Company through Mirkwood, where he and his pack of Orcs attack the Wood-elves as the Dwarves escape in barrels. Bolg and his pack continued to track down the Dwarves, which eventually lead them to Lake-town.
Around nightfall, Bolg and his Orcs arrive at Lake-town where they attack Bard's family in search of the Dwarves, but they only found four. When they attack, they are in turn attacked by Legolas and Tauriel who were tracking the Orcs down. He goes after Legolas, and the two begin a duel (in which Legolas uses Orcrist, the weapon that Thorin held during his quest to Erebor). While Legolas is distracted by other Orcs, Bolg withdraws from the duel and rides away on his Warg down a dock. He is then pursued by Legolas, who was now on a horse and chased after him.
Bolg later reports to his father that he was attacked by Legolas and Azog yells at him because the Elf Prince survived and would now send an army after the Orcs. He then tells Bolg to travel to Mount Gundabad and prepare a second Orc army for war along with swarms of Bats. Legolas and Tauriel follow Bolg to Gundabad and leave to warn the others. Bolg later appears at Ravenhill with his second army to aid Azog. Bolg knocks Bilbo out with his mace before finding Tauriel and badly injuring her in combat. Before he can finish her, Kili arrives and briefly duels the Orc but Bolg proves to be stronger and he impales Kili through the chest with his mace's hilt resulting in the Dwarf's death. In anger, Tauriel throws Bolg off the mountain and is dragged down with him. He is then spotted by Legolas and the two engage in a fierce duel ending with Legolas killing Bolg by stabbing a dagger through his head. The giant Gundabad orc then falls down to a large rock below, and was crushed by a giant boulder.
==== Personality ====
Hardly any different from Azog, Bolg is a murderous, callous, idealistic, merciless and cruel warrior. He is extremely sadistic, showing no qualms about massacring the Men of the Lake-town and even relishing Kili's death. He is also psychopathic and remorseless, shown by how he pitilessly orders the attack on Laketown. But he is highly intelligent, an excellent leader and tactician. Bolg is enigmatic and powerful, possessing immense strength of will and superb tactical ability. He shows himself to be just as pitiless as his warrior father and is almost unimaginably determined and ferocious. Despite this, he has a strong relationship with Azog as Bolg displays fierce loyalty to his father and a great desire to make him proud.
==== Abilities ====
Bolg is a skillful leader, which is likely why he was Azog's second-in-command of the Gundabad Orc pack. He is highly skillful in hand-to-hand combat and swordsmanship. His fighting style, (unlike Azog's preferred Warg-riding style that emphasized blows with heavy momentum) is emphasized with lightning speed and agility, as well as martial arts techniques and using the environment against his opponent. His skill as a fighter is later shown by how he is put in charge of the Orc packs whilst Azog stays to fight Gandalf. Bolg has an astonishingly high tolerance of pain, shown by the fact that he refuses to show pain or even bleed when Legolas plunges his knife into his hand nearing the end of their battle. Though his preferred fighting style is surely not Warg-riding, he is highly skilled at it.
