what are the big orcs in lord of the rings
Uruk-hai The Uruk-hai, described as large black orcs of great strength, first appeared from Mordor about the year 2475 of the Third Age, when they briefly took Ithilien and the city of Osgiliath. These original Uruks were of Sauron's breeding, but Saruman bred his own, which could endure sunlight. Due to their superior size and strength, the Uruk often looked down upon and bullied other breeds of orc.
Rings of Power The Rings of Power in J. R. R. Tolkien's Middle-earth legendarium are magic rings created by Sauron or by the Elves of Eregion under Sauron's tutelage. Sauron intended three of the rings to be worn by Elves, Seven by Dwarves, Nine by Men, and one, the One Ring, by the Dark Lord Sauron himself in Mount Doom.
