Phantom's Secret Plan! Another Cure Lovely! - S1.E30

As the girls try to figure out the secrets of the Shining Make Dresser, Blue reveals that Mirage was once a Pretty Cure herself who battled alongside him. Shortly afterwards, Megumi and Blue are confronted by Phantom, who uses Megumi's shadow to turn himself into a dark double of Cure Lovely named Unlovely. Armed with knowledge of Megumi's desire to help her mother, Unlovely uses psychological attacks on Megumi, leaving her vulnerable to her attacks. With Unlovely's power proving to outmatch the other Cures, Megumi is left doubting herself, but Hime and the others help to encourage her to stand up again, giving her the strength to fight against Unlovely, turning her back into Phantom. The Cures' innocent thoughts grant them the power to use the Shining Make Dresser and perform the Happiness Big Bang attack to beat Phantom.
