Beowulf’s abilities surpass further than normal people. The way Beowulf showed superhuman strength, intelligence, and/or courage was by the fight him and Grendel had. Beowulf tore off Grendel’s arm with his bare strength. Also he showed his strength by lifting a sword made by giants. Another example was that Beowulf’s men left his alone and he still fought the dragon. He showed courage in this battle he fought in.
Beowulf risks his life for the people and fame. In the battle against Grendel, Beowulf fights him with no weapons only his bare hands since Grendel did not use s weapon either. Beowulf risks death for the greater good of society. Also another achievement Beowulf did was he went into Grendel’s mother’s lair alone not knowing who or what was in there.
