Grendel, often called Gren for short

Grendel just wants to be left alone. In the old days he terrorized Norse mead halls, but lately he can be found occupying a stool in various quiet, dumpy bars around New York. He hates the noise of the city, but must work there to afford his glamour. Despite his gruff bearing, he's fiercely loyal to those who've learned to offer him the space and silence he deserves. Talking to him is like watching a time bomb tick down, it's only a matter of time

Grendel is violent, snide, crude, opprobrious, arrogant, hateful, sarcastic, brutal, temperamental, argumentative, impatient, always profane, and somewhat egotistical. He tends to keep to himself quietly, and as such, hates it when he is disturbed. He is shown to be an alcoholic, which would partially explain his violent temper. He also becomes vicious, aggressive, vengeful, hostile, and even homicidal when provoked. He also has a bold sense of morality*

However, Grendel (even though he turns violent in aggression at times) is fiercely loyal to his friends, as seen by when he defended Lily's funeral. He seems to be more concerned for Lily, more so than Holly, as he spoke up for her more often than Holly herself did
