Bragging is a common trait among heroes, and something that Beowulf has consistently done throughout the story. In lines 142-189 for example, Beowulf describes what a brave fighter he is and brags about how he killed 5 beasts in a single battle. To summarize, he says that he heard of the Danes' desperation and came to their aid, and while he was willing to risk his life to save Hrothgar and his people, it was obviously also for the sake of glory. He assures Hrothgar that the situation will be resolved and does his job well, killing Grendel as well as Grendel's mother after she seeks revenge by killing one of Hrothgar's best men. His arrogance appears again in lines 450-458, after he fearlessly enters the lake in which Grendel's mother lived. It says: “He leaned towards the lake/would wait for no one/answer; the tumultuous water covered it…”. Beowulf also fought Grendel's mother alone, and although he ultimately won the battle, it almost cost him his life. Ultimately, Beowulf met his demise at the end of the story, when he volunteered to fight a dragon that was terrorizing the Geats. In lines 606-612, after Beowulf delivers his final boast: "I never knew fear, when I was young I fought/In endless battles." I am old now/But I will fight again, seek glory again,/If the dragon hidden in his tower dares/To face me…”, he went to face the problem, only for his war sword to break and that his followers leave him afraid. Beowulf was essentially helpless until a single warrior came forward, named Wiglaf, and killed the dragon for him. Even though Wiglaf was not seriously injured, Beowulf was lying on the ground, knowing that he was dying and that these were his last moments on Earth, so he only asked Wiglaf that he be buried with the treasure that was in the castle where the dragon lived. This shows that even the toughest fighters like Beowulf are not as invincible as them.
