Smeagol:
* The original personality: Smeagol was a hobbit who lived in the Shire centuries before the events of "The Lord of the Rings."
* Kind and naive: He was initially a kind and playful creature who enjoyed fishing and swimming.
* The "Precious": He became obsessed with the One Ring, calling it his "Precious" and becoming corrupted by its power.
Gollum:
* The corrupted personality: As Smeagol became consumed by the Ring, his personality shifted into a more grotesque and twisted being called Gollum.
* Twisted and cruel: Gollum is characterized by his pale, slimy skin, large eyes, and unsettling speech patterns. He is obsessive, deceitful, and often violent.
* Driven by the Ring: Gollum's every thought and action is dictated by his desire for the Ring.
The Transformation:
Gollum represents Smeagol's corrupted state. He is a creature of darkness and malice, driven by the Ring's influence. Smeagol, the original, good-natured hobbit, still exists within Gollum, but he is weakened and suppressed. This is evident in moments when Gollum shows flashes of his former self.
In essence, Gollum is Smeagol's tragic, corrupted alter-ego, born out of the Ring's insidious influence.
