Red

The true main antagonist of the series and the ruler of the Phantom Empire, Red is a spirit who once oversaw the Red Planet. But after the Red Planet's people died out, Red became hateful and made his goal to turn the world under the protection of his brother Blue into a place of chaos by anger and hatred. Red assumed the alias of Deep Mirror for most of the series, appearing as a silhouette within a mirror. While he presents himself as Queen Mirage's advisor and often give orders to the commanders, his true role in the Phantom Empire is revealed when he intervened to stop the commanders from being purified and he influenced Mirage further through her love-spurred anger towards Blue before she is eventually purified. This forces Red to take a more active approach in destroying the Pretty Cures, using Seiji as his new servant while summoning the red planet for a worldwide attack. But after losing his follower, Red personally battles the Pretty Cures before being defeated Megumi as Forever Lovely. After his defeat, Red finally reconciles with Blue and decides to restore his planet to its past glory with the aid of his brother and Mirage. He is based on the Magic Mirror from Snow White.
