Beowulf vs Luke

Luke Skywalker and Beowulf have a lot of similarities and differences when it comes to relating them to being heros. For one, Beowulf was born into royalty, while Luke was not. They were both basically born to be heros. Luke's father was a fighter so it's only likely that his child follow in his footsteps. Beowulf was born to fight because he's basically the best fighter around. He felt he was destined to fight and it seems that Luke will start to realize this too as the plot goes on.
They both also have similar calls to actions, however. Beowulf must fight because a neighboring area is in need of help and he feels it's his duty to save them. Luke is called to fight because Obi Wan needs his help delivering a message in order to save the area. Though Luke doesn't accept the challenge right away it's still similar to Beowulf's because it's being the hero to a certain area in the world (or galaxy). We later find out that he mainly fights because his parents were killed by opposing forces.
A difference between the two would be their mystic weapons. Beowulf's mystic weapon would be the sword he received to fight Grendal's mother. Luke's weapon would be the force that he begins to discover as the movie progresses.
In the end of Star Wars, Luke really hasn't mastered two worlds yet. We sort of get a sense that in time he will be able to master two worlds, but not yet. Beowulf, on the other hand, ended with Beowulf being the master of both Denmark and Geatland.

WIGLAF

Wiglaf in many ways is similar to Beowulf. They both possess the courageous, strong, and loyal traits but each one uses these in different ways. Beowulf uses his powers because he knows he's the best. Beowulf knows that it's his destiny to do what he does. Wiglaf on the other hand uses his powers mainly to help Beowulf. He feels a need to assist Beowulf in his journey and with them working together he feels they can conquer anything. Both do have some notable differences though. For one, Beowulf is more independent. He feels that he knows everything and that he doesn't need anyone. Sadly, he's proved wrong when he gets a deadly wound from the beast. If he had decided to focus more on teamwork he might've not gotten this wound. Wiglaf focuses more on teamwork and planning everything around that. His heroism is displayed when he goes up against the beast even when Beowulf is down. He has great persistence even when the odds are against him. Wiglaf doesn't feel he's the only one who can defeat the monster but he feels he must at least attempt to fight in order to show loyalty to his leader. As Wiglaf said, "I would rather my body were robed in the same burning blaze as my gold- giver’s body than go back home bearing arms." This quite shows just how loyal he is to Beowulf and how he’d rather die trying to prove this than simply run away to safety

Beowulf

I believe Unferth was trying to do this to get everyone to realize that all Beowulf wants is to be known for his accomplishments. He feels Beowulf is only helping people for popularity and not for the mere fact of using your gift for the greater good of the people. Unferth probably did this because he wants people to realize him as the real hero. He wants to be known as the fighter who’s better than Beowulf so he’s trying to point out everything that he thinks Beowulf is infamous for. This is to get him known as the hero, rather than a lesser version of Beowulf. Beowulf first replies by saying that Unferth's accusations were caused by his drinking. He then went on to talk about how they both boasted when they were young hinting that if Becca were to win he would have done the same thing. Following that, Beowulf tells of how he's the best and that Becca would never have been able to beat him. This shows he's a hero because he doesn't think he's the best, he knows it. This is a real characteristic in a hero because they have no doubt that anything they attempt to do they will succeed in. Beowulf also never really disagreed with the comments that Unferth was saying. He knows that he will always brag about his accomplishments but the real deal is that Beowulf just knows that he’ll be good at everything. He doesn’t do it for bragging rights but more to prove to himself that he’s the best at everything he attempts.
