Gothmog (Balrog)

Gothmog (Sindarin IPA: [ˈɡoθmoɡ] ) was the Lord of the Balrogs during the First Age and was the greatest Balrog ever to walk Middle-earth. He was the High Captain of Angband, one of Morgoth's most trusted generals, leading the Dark Lord's forces to victory in countless Battles. His only equal in rank was Sauron. Gothmog, like the rest of his kind, carried a fiery whip into battle, but he was also known to have wielded a great black axe, which was feared by elves across the continent of Beleriand.

Etymology
Gothmog's Quenya name was Osombauko (or Oþombauko; Tengwar: full spelling `N3Hw.EaY or vowel-abbreviated spelling `N3Hw.aY ; IPA: [osomˈbaʊko] or Vanyarin [oθomˈbaʊko] ).
