Sabaku

Sabaku, often called Professor Sabaku (サバーク博士), is the leader of the Desert Apostles, who wishes to kill the Tree of Hearts. He is usually seen sitting on a chair on a high level in the Desert Apostles' base, always having his right-hand Dark Pretty Cure by his side. He is never seen without his mask. His personality has not been shown properly, however, he wishes to finish off the newest generation of Pretty Cure in order to take down the Tree of Hearts.

Fight Before the Tree of Hearts
It is unknown how old Sabaku is and how long he has been planning to take over the Tree of Heart, but it seems like Hanasaki Kaoruko knows who he is, which might mean that they have met though it has not been stated.

Some time shortly before the present storyline, Sabaku watches as Dark Pretty Cure fights Cure Moonlight before the Tree of Hearts, now having come to his goal of taking control of it. When he vitnesses Cure Moonlight's defeat, he is surprised that the Three of Hearts has not died even when all its flowers has fallen. Cure Moonlight tells him that as long as Pretty Cure exist, the Tree of Hearts will never die. Sabaku allows Dark Pretty Cure to finish her off, but notices that two fairies, Chypre and Coffret, escapes with two new Heart Perfumes, which are one of the items for Pretty Cure. After watching Cure Moonlight lose her Pretty Cure Seed, Sabaku orders Sasorina to find and take the Heart Perfumes to him.

New Pretty Cure
Soon, when Sasorina appears before him to report, he is told by her that a new Pretty Cure has appeared; a Cure named Cure Blossom who is said by her to be one of the weakest Cures in history, which makes him let her try once again to get rid of her, knowing that he will never conquer the Tree of Hearts as long as there are Cures in existence. However, Soon a second Cure join the new Pretty Cure; Cure Marine, who Sasorina claims is somewhat stronger than Cure Blossom, although Sabaku listens to Kumojacky's claim that not even a hundred Cures can win against him, and lets Kumojacky try to defeat Pretty Cure in Sasorina's place. When Kumojacky fails, Sabaku tells Kobraj to try defeating Pretty Cure.

After a long time with defeat after defeat from the Desert Messengers, Sabaku tells a Snackey to report to Kobraj that he must hurry to defeat Pretty Cure, as his patience is wearing. Finally, Sabaku is tired of watching his henchmen fail, and orders Dark Pretty Cure herself to meet up with the new Pretty Cure.

Relationships
Cure Moonlight: While they are viewed as enemies in the season's prologue, the opening sets Sabaku and Cure Moonlight together, hinting of a special relationship between them. This relationship is not revealed to be more than that of nemesity.

Dark Pretty Cure: Sabaku seems to trust Dark Pretty Cure whenever he wants to get somethingdone 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.

Desert Apostles: Unlike Dark Pretty Cure, Sabaku does not seem to be as close to the rest of the Desert Apostles, mostly just seeing them whenever they report to him or ask for permission to go and try to defeat Pretty Cure.
