Many of the enemies in Skies of Arcadia are palette swaps of each other, including a few bosses. These monsters share the same base model and battle themes, but have differnt coloring, levels of strength and, in seldom cases, elemental resistances. Therefore, it is worth arranging and presenting the monsters in the game by appearance-based "lineage".
