J. R. R. Tolkien's presentation of heroism in The Lord of the Rings is based on medieval tradition, but modifies it, as there is no single hero but a combination of heroes with contrasting attributes. Aragorn is the man born to be a hero, of a line of kings; he emerges from the wilds and is uniformly bold and restrained. Frodo is an unheroic, home-loving Hobbit who has heroism thrust upon him when he learns that the ring he has inherited from his cousin Bilbo is the One Ring that would enable the Dark Lord Sauron to dominate the whole of Middle-earth. His servant Sam sets out to take care of his beloved master, and rises through the privations of the quest to destroy the Ring to become heroic.

Aragorn is a fictional character and a protagonist in J. R. R. Tolkien's The Lord of the Rings. Aragorn was a Ranger of the North, first introduced with the name Strider and later revealed to be the heir of Isildur, an ancient King of Arnor and Gondor. Aragorn was a confidant of the wizard Gandalf, and played a part in the quest to destroy the One Ring and defeat the Dark Lord Sauron. As a young man, Aragorn fell in love with the immortal elf Arwen, as told in "The Tale of Aragorn and Arwen". Arwen's father, Elrond Half-elven, forbade them to marry unless Aragorn became King of both Arnor and Gondor.
