Grendel is the monster who lived for around eleven years that terrorized a bunch of people that had settled at castle. He enjoyed when people were scared of him. He was grand and gruesome with red scary eyes and horrible teeth.
The people who were at the Heorot castle were scared because they knew what Grendel could do and what kind of beast they had to face and that is why no one was brave enough to face Grendel at the time. With having that potential and strong body Grendel took over the castle and every one lived in the dark for it until Beowulf showed up.
