Beowulf
The Geatish warrior and later king at the center of the poem. Young Beowulf fights for glory and to prove himself. Old Beowulf fights to protect his people. He is physically extraordinary but also defined by his code of fairness and his willingness to face danger alone.
Grendel
A monster descended from the biblical Cain who attacks Heorot for twelve years. He represents chaos, exclusion, and resentment of human joy. He is powerful but vulnerable: Beowulf kills him by exploiting the one thing Grendel did not expect, someone who could match his grip.
Grendel's Mother
She attacks Heorot to avenge her son's death. In some ways she is more dangerous than Grendel because she acts with purpose and retreats to a defended lair. Her fight with Beowulf is the hardest of the first two battles and forces Beowulf to improvise.
Hrothgar
The aging Danish king who built Heorot and cannot protect it. He is not weak, but he is past his fighting prime. He becomes a mentor figure to Beowulf, warning him about pride and the dangers of power. His speech to Beowulf after the second monster is killed is the poem's clearest statement about what can go wrong with a great warrior.
Wiglaf
A young Geatish thane who is the only one of Beowulf's men to stay and fight the dragon. He represents the next generation of loyalty. After Beowulf dies, Wiglaf delivers the poem's harshest judgment on the men who fled. He is named Beowulf's successor.
Unferth
A Danish warrior who challenges Beowulf's reputation at the feast in Heorot. He lends Beowulf his sword Hrunting before the second fight, which is a form of respect. He shows that even skeptics recognize real courage when they see it.
The Dragon
A creature that has guarded a buried treasure hoard for three hundred years. When a thief steals a cup, the dragon burns Geatish villages in retaliation. It is not a thinking villain but a force of destruction. It kills Beowulf and represents the kind of threat that age and experience cannot fully prepare a warrior for.
