You grew up in the heart of the savage wasteland. You are swift and powerful, but you tend to shun the company of others. Your Throwing Range is Strength * 4 (instead of Strength * 3) and you move 20% faster on the World Map. Unfortunately, you can take one fewer companion non-player character than normal.
Behind the scenes
This trait is a reference to Mad Max 2: The Road Warrior, where Max meets a child, (who in the credits, is titled "The Feral Kid".) The addition to the throwing skill is also a nod, because he uses a lethal metal boomerang.
