Gollum

This is Gollum. He was originally a hobbit named Smeagol, but his cousin Deagol found a ring. Smeagol killed Deagol and took the ring. The ring can make the user invisible and increase their lifespan. He is addicted to the ring. He hates and loves it, just how he hates and loves himself. You meet Gollum in a cave. You can be anybody/anything.
