The Illusionsts are merely three copies of Layazero, which could be explained by the holographic nature of Layazero itself, copying itself and creating two duplicates. The Illusionists do not have a mission, and upon defeat, the player is taken to the middle Meteo of the Multi mode of Star Trip, and is given the neutral ending.
