Answer:
Bilbo Baggins is the main character and in fact, he is a hobbit. He is half Took and half Baggins, the Tooks are far more adventurous than the Baggins. In the Hobbit, Bilbo goes on an adventure with 13 dwarves and Gandolf the grey in the Middle Earth period to get back the lost treasure of the dwarves' ancestors.
