Dark Pretty Cure

Dark Pretty Cure appears in Hanasaki Tsubomi's dream, where she fights against Cure Moonlight before the Great Tree of Hearts. Although hurt, Dark Pretty Cure manages to get the upper hand in the battle, and succeeds defeating Cure Moonlight. She is later seen beside Sabaku whenever a Desert Apostle has audience with him, acting as his second-in-command. In the preview for the tenth episode, Hanasaki Tsubomi and Kurumi Erika claim that Dark Pretty Cure has lost her heart, though it is unknown if this will have a deeper meaning later on.

Before the Tree of Hearts
Dark Pretty Cure is first seen fighting against Cure Moonlight before the Tree of Hearts, telling her that she will die with the Tree of Hearts. They eventually take use of their Flower Tacts, her Dark Tact, and Cure Moonlight's Moon Tact. After being lightly wounded, Dark Pretty Cure succeeds in making Cure Moonlight deform half-way and have the Tree of Hearts wilt, but not die. Cure Moonlight explains that this is because it will never wilt as long as Pretty Cure exist. When she hears this, Dark Pretty Cure prepares herself to use Dark Forte Wave to take Cure Moonlight down, but Cure Moonlight uses her Pretty Cure Seed to protect herself and the two fairies Chypre and Coffret, holding it back long enough for the fairies to escape with two Heart Perfumes. Just then, the Dark Forte Wave manages to destroy the Pretty Cure Seed, and Dark Pretty Cure allows a moment of schock to be shown on her face before the attack hits Cure Moonlight.

New Pretty Cure
Throughout the rest of the time afterward, Dark Pretty Cure is seen beside Sabaku in the base of the Desert Apostles, always observing whenever someone comes to ask for permission to go and defeat the new Pretty Cure. Although she has yet to give any reactions herself when the news of a new Pretty Cure is revealed, she is told to go and fight them when Sabaku's henchmen continue to lose.

Relationships
Cure Moonlight: Dark Pretty Cure's relationship with Cure Moonlight seems to be the antagonistic sort. However, just when Cure Moonlight's Pretty Cure Seed is destroyed, Dark Pretty Cure gets a shocked expression, hinting a deeper relationship between the two of them.

Sabaku: Sabaku seems to trust Dark Pretty Cure whenever he wants to get something done throughoutly. Because it is unknown if Dark Pretty Cure is a real Cure or not, it is not known if Sabaku is willing to sacrifice her in order to take control of the Tree of Hearts when the rest of Pretty Cure are defeated.
