Bred in the depths of Morgoth's fortress Angband as an engineered instrument of war, Ancalagon is introduced in later versions of Tolkien's Quenta as the leader of the first winged dragons unveiled by Morgoth during the War of Wrath. He appears at the end of the First Age (accounts place the War of Wrath in year 587 of the First Age in the secondary summaries) when the Valar and their allies assault Angband; his deployment is presented as Morgoth's last resort to stem the Valar's invasion.
Described in the available sources as a dragon of immense scale, Ancalagon is specifically called 'the greatest of the dragons,' 'winged and black.' Tolkienian etymology ties his name to Sindarin elements meaning 'jaw' and 'rushing' (glosses such as 'impetuous jaws' or 'jaws-rushing'), emphasizing a powerful biting maw as a distinctive feature. Beyond these attestations—great size, black colour, wings, and an impressive jaw—primary descriptive detail in the supplied materials is sparse.
Ancalagon inaugurates and leads the first winged dragons in Tolkien's later accounts: his flight and aerial assault are central to his role in the War of Wrath. Secondary summaries report that his coming caused the Valar's forces to 'retreat before the thunder, lightning and hurricane of flames that preceded the dragons,' indicating overwhelming destructive might in aerial warfare. In the climactic duel he commands winged dragons in prolonged aerial combat; he is ultimately pierced and shot down in battle (Eärendil in Vingilot, aided by Thorondor and great eagles), and his fall upon the peaks of Thangorodrim causes catastrophic geological destruction.
