Monsters born of Dark Gaia with exceptionally high intelligence can take on a humanoid appearance like these fiends. Their magical empowerment raises their allies' attack strength. Try to take them out before they can get a spell off! — Description, Sonic Unleashed
The Power Masters' basic appearance is that of a humanoid phantom-like wizard. They are dressed in oxford blue clothes which have a pointy hat and cape, and are decorated with magenta symbols. The only parts on their body that are shown are their yellow eyes and some of their back faces. They are also always carrying a magenta staff with a round head.
Powers and abilities
The Power Masters are able to move around by teleporting into an area in a puff of purple smoke. As a Dark Gaia minion, the Power Masters can possess people by latching onto the deepest, darkest part of the heart, and generate despair, negative emotions or even erratic behavior that are completely opposite to the person's personality.
The Power Masters are born with exceptionally high intelligence. They are capable of casting spells that increase their allies overall strength and durability. These spells are not limited to other members of Dark Gaia's Minions, but also robots, and will remain active until they wear off on their own, even if the Power Master that cast it is killed. When casting their spells, the Power Masters form a circular spell seal under them and send out purple orbs that will target their surrounding allies and empower them upon contact, which is signified by a pink aura appearing. They also have the innate ability to levitate above ground and move through mid-air rather quickly.
The Power Masters possess some skills in stick fighting, being able to use their staffs in close combat to hit their opponents using quick and swift movements. As a supplementary ability to their stick fighting, the Power Masters can enlarge their staffs, giving them greater range and attack power.
The creation of the Power Masters and the rest of Dark Gaia's Minions occurred when Dark Gaia broke apart in the beginning of Sonic Unleashed due to its premature awakening by Dr. Eggman. These fragments were then spread across the Earth and became Dark Gaia's Minions, with the Power Masters some amongst them. Due to being born with high intelligence, they are able to take on a near-perfect humanoid appearance. They first appear in Dragon Road Night Act 1.
In gameplay, the Power Masters can temporarily make all nearby enemies stronger with their spells, increasing the overall damage they can deal to the player and their defense against attacks for a short time. The Power Masters also always appear alongside other enemies to use their empowerment abilities, though there are never more than one of them in one area. They are usually paired up with a Cure Master.
In battle, the Power Masters focus foremost on casting their empowering spells, though they can also attack the player with their staff by either using it like a club or by hammering it down on Sonic when enlarged. Additionally, the Power Masters can move around in the air to avoid damage which make them hard to attack.
Upon the reconstruction of Dark Gaia by Dr. Eggman, all of the Power Masters along with the other Dark Gaia minions were returned to the beast, who was later defeated and sealed within the planet's core.
