Merak (メラク) is a secondary villain of Lucky☆Pretty Cure!. He is one of the four competitors in the Greed Empire's Rite of Succession, and the last one to make his appearance. His ultimate goal is to collect all the knowledge in the universe, and sees the Greed Empire's library as a stepping stone towards that goal.
Merak has short black hair and gray eyes. His hair sweeps to the right, concealing his right eye. He wears a pitch-black, coat-like robe with silver trimmings, as well as black gloves and boots.
Merak is a mage and an intellectual, who believes his logic is infallible, and is usually condescending to others. He hides his true nature beneath a benign smile and silver tongue, preferring to deceive and manipulate others into doing his bidding. He also has a habit of concocting detailed plans and schemes, carrying them out with absolute precision.
Like the other competitors, he is able to summon Kyoujins using a cube given to him by the Greed Empire. He also possesses several coffin-shaped devices called Graves, capable of remote recording and playback, shown during his first appearance. In chapter 12, they are shown to also have combative abilities, transforming into floating turrets or energy blades that he can wield. Merak also has the ability to fly.
- Merak is named after one of the stars in the constellation Ursa Major, aka The Big Dipper. He is also named after the Maserati Merak sports car.
- The color of the symbol on his Kyoujin cube is purple.
- He is the only competitor whose name isn't derived from a synonym for greed.
- Merak shares the same voice actor as Batty from Mahou Tsukai Pretty Cure!.
