The Red Demon, Lesser Demon, and Mad Demon are species of monsters randomly battled in Golden Sun: The Lost Age. These monsters, resembling hefty horned and winged demons with vaguely wolf-like faces, are palette-swapped variants of each other that have differing levels of power and defense and are fought in different locations in the games. This monster line is notable for being quite tougher than other monsters fought in their areas, and that each monster drops a unique piece of equipment not found anywhere else.
