|Affiliation: Dark Gaia|
They are similar to the Dark Master in terms of appearance, but the hat is colored in a dark purplish tint. Their specialty is the ability to raise their allies' attack strength. They will always appear where there are groups of enemies, but there will never be more than one of them at a time. They can also be paired up with Cure Masters.
Power Masters will generally focus on empowering, but they will also attack Sonic the Werehog if he approaches them by swinging their staff like a club or by hammering it down on him. They can also move around in the air to avoid damage, which makes them hard to hit.
|“||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!
