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".
Oswald Cobblepot (Gotham)
Cobblepot eventually gets revenge on Tabitha for his mother's death when he stabs her in the heart. Along with Riddler, he allies up with Jim Gordon and other police officers in order to fight Bane's forces and protect Gotham. Ten years later, an older and slightly overweight Cobblepot (who has now fully embraced his criminal persona Penguin) escapes from police custody along with Riddler. The pair is hunted down and subdued by a mysterious vigilante - The Batman.
