Gollum is a complex character from J.R.R. Tolkien's The Lord of the Rings and The Hobbit. Once a creature named Sméagol, he was transformed by the corrupting influence of the One Ring, which he referred to as 'my precious.' Gollum embodies the struggle between good and evil, showcasing the effects of obsession and isolation. His dual personality, Gollum and Sméagol, represents the conflict within him. Gollum is cunning and treacherous, while Sméagol shows glimpses of his former, kinder self. This internal battle makes Gollum one of the most memorable and tragic figures in fantasy literature.
