From the fictional world of J. R. R. Tolkien.

Lord of Balrogs, Gothmog was of rank almost equal to that of Sauron. He carried a black axe and fought in the Dagor-nuin-Giliath, where he mortally wounded Fëanor. He killed two Kings of the Noldor: Fëanor in the Dagor-nuin-Giliath, and Fingon in the Nirnaeth Arnoediad. He also led the assault on Gondolin and was there slain by Ecthelion of the Fountain, an Elf-lord.
