Who IS Bilbo Baggins?

Bilbo Baggins is the main character of the story. He is a hobbit who prefers domesticity to adventure, but he soon finds himself caught up in the escapades of Gandalf, the wizard, and a group of dwarves. Bilbo is hardly the raw material of a hero, but as the story progresses he develops into a clever and brave hero. Throughout the novel, he longs for his home but he is able to perform his duties as a member of the group. Finding the ring that makes him invisible is certainly the greatest tactical advantage that he gains in the story.
