Dim Dragon

The Dim Dragon is the second boss encounter in Golden Sun: Dark Dawn. It is fought at the end of the fourth course of the Psynergy Training Grounds. It is a direct throwback to the Doom Dragon, appearing as a clockwork mechanism on wheels with wooden planks painted with a caricature image of the three-headed dragon grafted onto its front and back. Like with everything before in the Psynergy Training Grounds, this man-made contraption constitutes a trial that thematically represents the original challenges Isaac and the Warriors of Vale had to meet thirty years before.

It can physically attack, use Scary Jinx to set a Death Curse, exhale Sizzle Breath to deal surprisingly heavy damage to one Adept, as well as exhale Gasping Breath for some damage against all Adepts. Sometimes it will go "out of order" for two turns, at the end of which it will perform repairs on itself and heal 35+ HP and then be able to fight normally again.

Despite appearing like nothing menacing at all, it is the first "actual" boss encounter in the game. Even so, it is possible to win simply by having all three Adepts attack every turn. When defeated, it rewards 179 experience points, 60 coins, and a Nut.
