These are two versions of a playable Frodo Baggins character. The first is a fighter level 5, and the second is a fighter level 30 (there is no indication in the Lord of the Rings novels that Frodo had any special skills or abilities; therefore, it seemed appropriate to make him a fighter, the "default" class).
Each of the two versions also comes with 5 special items: Sting, a suit of Mithril armor, a Cloak of Lórien, the Light of Eärendil, and, of course, the One Ring. The level 30 Frodo has more powerful versions of these items than the level 5 Frodo.
