Brad Hill is a pre-made townie from Oasis Landing who can be seen wandering around town. He can be made playable by marrying him, or asking him to move in.
He could possibly be related to fellow townie Cadin Hill from the same world, as both shares their last name and looks. However, this is not stated in his family tree. Like all pre-made Sims from Oasis Landing, he has the Future Sim hidden trait. He has mastered his Advanced Technology skill and has 4 skill points in Laser Rhythm-a-con.
