Next: Glaurung vs. Thuringwethil

While Glaurung the Deceiver is well-known, here's some
info on his worthy opponent (from Tolkien Gateway):

Thuringwethil (perished First Age c. 465) was a Vampire servant of Sauron during the First Age. She was Sauron's messenger, but was caught in the battle between her master and Lúthien and Huan at Tol-in-Gaurhoth ("Isle of Werewolves"). She was slain either by the Hound of Valinor or in the collapse of Minas Tirith. Lúthien later used her cloak to sneak into Angband during the Quest for the Silmaril.

Because of Thuringwethil's ability to change forms, she may have been a Maia.

[edit] Etymology
The name Thuringwethil is difficult to translate. The direct translation is "Secret Sister" (from thurin = "secret, hidden" and gwethil = "sister, associate"), but Tolkien took her name to mean "Woman of Secret Shadow".
