Azog

Azog was an Orc chieftain who commanded the Moria Orcs from at least TA 2790 until his death at TA 2799.

Azog was the nightmare of Durin's folk.The king of the Dwarves,Thror himself was killed by Azog by beheading him.He ruled over the abandoned mines of Moria during the late third age and became the leader of the Moria Orcs.He initiated the war of the Dwarves and Orcs who had come to revisit Moria kingdom of the Dwarves.At some point he has a son named Bolg.And he became the common enemy for the Dwarves.Because of all that and including torturing of Thror for 2 days,he is feared by any Dwarves except Thorin Oakenshield,son of Thrai,son of Thror who dares to face Azog himself.
