Purple orbs has the ability to lights and lights up sections to make it more easier to run in the stage. There are also more solid types of these orbs that has the same work, but they are required to open doors in the stage. The Purple Orbs are also useful in the battle with Iblis, as they serves as the main way to make him approaching the player and to attack his green eye. To use the Purple Orbs in gameplay, the player has to use Homing Attack on Purple Orbs or using Silver's Psychokinesis to use it. In Silver's case there is one difference is that the player has to use the Psychokinesis to use it and continue grabbing the orb, because if the player levitates or stops grabbing it, then the Purple Orb will be destroyed.
