A Dane, the son of Ecglaf, and a follower of Hrothgar. Unferth is presented as contrast to Beowulf, providing a glimpse of a poor warrior in contrast to Beowulf's good warrior. Unferth is boastful, just as Beowulf is, but unlike Beowulf Unferth lacks the moral courage to back up his boasts (and unlike Beowulf Unferth never does anything to stand against Grendel). Further, Unferth appears to be jealous of Beowulf and never responds to Beowulf's taunt that Unferth once killed his own brother, which could signal either Unferth's incompetence or some sort of moral failing. Unferth does become more generous after Beowulf defeats Grendel, and lends Beowulf his family sword to fight Grendel's mother.
