Beowulf depicts the creature as a ravenous, animalistic-type beast. He is apparently driven by an animal-like instinct as he ruthlessly attacks the Danes. He unsympathetically rips apart his victims and drinks their blood, enjoying the taste of their flesh. The readers are unable to sympathize with the character and he is considered to be the antagonist of the story. In Grendel, however, Gardner approaches the beast in a completely different manner.
In Gardner's novel, Grendel speaks from a first person point of view and we discover that he is not so much the brutal and heartless beast that everyone believes he is, but rather a perpetually misunderstood, lonely creature. In this story the monster is given more of a personality and humane quality. He struggles to understand the human race, when every attempt is instantly shot down because of the fear he instills into every creature he comes across. In Grendel, Grendel is nothing more than a misguided being who is trying to find a purpose in life and acts violently as a result of fear. Readers are able to more closely identify with Grendel in this story and cannot help but to empathize with the monster whenever he is victimized by others. In this novel he is considered as the protagonist of the
story.
