Grendel's Mother in Beowulf

Grendel's Mother

Grendel's mother, another demonic descendant of Cain, attempts to avenge her son's death by attacking Heorot Hall. Although she manages to kill one man, she is alarmed by the strength and prowess of the Geatish warriors, and retreats to her lair, a cave underneath a lake filled with sea monsters.

Beowulf follows her to her lair and beheads her with a sword that he finds there. Although she isn't nearly as strong as her man-eating son, Grendel's mother fights like an Amazon warrior, and Beowulf has a tough time defeating her.
