Arriving at Earth
Dune arrived at Earth and sent a Desert Seed down to Earth which quickly turned into a Desert Devil. The Desert Devil was defeated by the Pretty Cures with the aid of the newly aquired powers, the Super Silhouette. At Christmas Dune returns to Earth and is after the power Cure Flower sealed of his from their battle. The Cures attack Dune seemingly getting the upper hand. As the dust settles Dune is still standing and then goes on the offensive against the Cures. Taking out Moonlight first quickly followed by Sunshine and Marine he then turns his attention of Cure Flower. Cure Blossom tries to stop him but is unsuccessful and also falls to his power. Dune and Cure Flower then fight but she also is no match for him in her weakened state and defeats her. Leaving for his fortress with Kaoruko the Cures are left defeated and unconscious. He then proceeds to regain the power Cure Flower sealed away in her necklace by breaking the necklace. The great heart tree then arrives and Dune shatters the barrier protecting it and forces Kaoruko to witness him make the great heart tree wilt fully. However this did not break the spirits of the those who had been purified by the Pretty Cures allowing hope to still exist and furthermore allow the Cures and their fairies to retain their powers regardless of what he had done to the tree.
The Final Battle
Dune arrives shortly after Dark Cure's defeat and begins to battle Sabaku, Moonlight joins the fight protecting her father from a barrage of energy shots from Dune. Blossom joins the fight only for Dune to create a dark energy bomb which explodes breaking the Pretty Cure transformation and leaving all 3 on the ground. As Dune prepares to do the same Yuri's father runs to the dark energy and uses himself to shield his daughter and Tsubomi from the explosion. He tells Yuri to look after her mother and as she runs to her father the energy explodes leaving only taters of her father clothes. Enraged by Dune's actions, Yuri prepares to engage him in battle only for Tsubomi to grab her arm begging her not to fight with anger and hatred. Yuri tells Tsubomi that she despises Dune since he is the reason why she has lost both Cologne and her father.
Tsubomi again reminds Yuri that the Yuri she looks up to would never fight out of anger and would not be willing to do what she is about to and gives Yuri the remains of her Heart Seed that Dark Cure possessed, helping Yuri remember that Pretty Cures fight with love. The two transform into Blossom and Moonlight and begin to battle Dune. Just managing to keep the battle equal between them until Dune shoots dark energy at them which exploded on impact. As the dust settle Marine and Sunshine are revealed to have saved them from the attack and they join Moonlight and Blossom in fighting Dune. All the four Cures use their Forte Wave attacks against Dune followed by Marine and Sunshine combining to use Floral Power Fortissimo and Blossom and Moonlight to combine to use the same. All four hit Dune at the same time and then call fourth the HeartCatch Mirage and use HeartCatch Orchestra against him.
However, even the HeartCatch Orchestra wasn't enough to stop Dune and he broke free, telling the girls that their love would never overcome his hatred. Growing to a humongous size through his power, he begins assaulting the Earth. The Cures face him one last time, Blossom telling him that their love may not be strong separately, together they can overcome him and everything else. Using the power of the HeartCatch Mirage, the four HeartCatch Cures merge into Infinity Silhouette and with the Pretty Cure Fist Punch, defeat and purify Dune. As he disappears, the Earth is restored to normal.
Sabaku: Sabaku is Dune's right hand who dealing with the Cures while he is still restoring his energy after his final battle with Cure Flower. Sabaku is fearful of Dune and has warned his minions that if they fail Dune will make them pay dearly.
Hanasaki Kaoruko/Cure Flower: Was the last Pretty Cure to face Dune in battle. The fight was so intense that Cure Flower had to push her power levels to the max with the aid of the Heartcatch Mirage that she lost her ability to become a Pretty Cure, but she succeeded in causing Dune to retreat for another 50 years. She is also able to sense that Dune is returning.
- During a transmission to Sabaku and Dark Cure, a dark colored creature can be seen on Dune's left shoulder. It is unknown what this creature is or if it is merely part of Dune. It is possible it could be similar to the fairies and is what grants him is power. Its origins are also unknown.
- Even after 50 years it would appear Hanasaki Kaoruko still has a connection with Dune, as she can feel he is returning. This connection could be explained with the fact Cure Flower sealed his powers and it is that which is what connects the two.
