Gage Briody is a pre-made townie living in Sunset Valley who can be seen wandering around town. He can be made playable by marrying him, or asking him to move in.
He also has a double who is exactly like him, who can be found in CAS saved Sims. All of his facial characteristics have sliders set to neutral. This occurs with all other Sims randomly generated by the game as well. This is nicknamed "pudding face."
Because his hair is shaved and his eyebrows are brown, his hair appears to be brown. But, if he is given a longer hairstyle it can be seen that his hair color is actually a shade of blond.
