Grendel

Grendel is the primary antagonist of the Old English epic Beowulf, composed between the 8th and 11th centuries. Described as a monstrous descendant of Cain, Grendel terrorizes the mead hall Heorot in the kingdom of the Danes, killing warriors until the hero Beowulf confronts and defeats him in single combat by tearing off his arm. The character reflects early medieval Christian and pagan themes, embodying exile, vengeance, and the chaos beyond civilized society. Grendel remains one of the most iconic monsters in English literature.
