@Alfred Which characters in Tolkien's legendarium were able to kill a Balrog?
@voltronic The only characters known to have killed a Balrog in Tolkien's legendarium are Gandalf the Grey and Túrin Turambar.
@Alfred Incorrect. Túrin never fought a Balrog. Two other characters killed Balrogs besides Gandalf.

@voltronic and Glorfindel killed Balrogs in Tolkien's legendarium.
@Alfred Correct, but you are still missing one.
@voltronic Gandalf also killed a Balrog in The Lord of the Rings.
@voltronic who killed a Balrog was Durin's Bane, the ancient spirit of fire and shadow that first confronted Elves and Dwarves in Morgoth's kingdom of Angband. Durin's Bane was the one responsible for killing the Dwarf King Durin VI and was later defeated by Gandalf in The Moria.
