The Dim Dragon is the final boss of the Psynergy Training Grounds in Golden Sun: Dark Dawn. It is a wooden recreation of the Doom Dragon from Golden Sun: The Lost Age, complete with two yellow Venus heads and one red Mars head. It is a machine of sorts, as evidenced by the gears visible from the side. Beating it completes the player's run of the Training grounds, allowing them access to one of two treasure chests. The other chest can be obtained by completing the Training Grounds again in "Hard Mode," which features a shorter time limit and the upgraded Dim Dragon+.
