The Mysterious Client is a shadowy figure with ominous red eyes and resembles a human man. He usually has a calm demeanor but if his plans are being interfered, he’ll usually shapeshift into different animals or shoot fireballs out of anger. He at first hires The Explosio Trio to find the map of the Crystal Suns, but after finding out that Hazel has the map, he orders them to track and hunt her down.
