Gollum
Gollum is a fictional character from J. R. R. Tolkien's legendarium. He was introduced in the 1937 fantasy novel "The Hobbit", and became an important character in its sequel, "The Lord of the Rings". Gollum was a Stoor Hobbit of the River-folk, who lived near the Gladden Fields. Originally known as Sméagol, he was corrupted by the One Ring and later named Gollum after his habit of making "a horrible swallowing noise in his throat".

In "The Return of the King", Sam single-handedly rescued Frodo from Cirith Ungol and, dressed in scavenged Orc-armour, the two began to make their way across the plateau of Gorgoroth. They finally arrived, against all odds, at Mount Doom, the only place where the Ring could be destroyed. However, Gollum had secretly followed them all the way, seeking a chance to surprise them and take the Ring. When Frodo and Sam had almost reached their destination, Gollum attacked them, but Frodo threw him down. Sam faced Gollum on his own, letting Frodo continue up the mountain to finish their mission. Like Bilbo and Frodo before him, Sam spared Gollum's life out of pity, and turned his back on the beaten (but still wily) creature and followed Frodo.
