The Desert Devil is a powerhouse in Dune's army in Heartcatch Pretty Cure! He sends the Desert Devil to a thriving planet full of life, allowing it to turn the planet into an endless lifeless desert.
Dune contacts the Pretty Cures and tells them he will be sending a Desert Seed to Earth and that the Desert Devil will turn all the greenery into a desert. Dune quickly shows the girls a demonstration. The four watch as a Desert Seed is fired at a planet full of life. When the Seed impacts the planet, it quickly turns into a desert and the four girls are left with no other option but to go back to the Pretty Cure Palace and take the Ultimate Test to gain access to the Super Silhouette.
Obtaining the New Power
Dune sends a Desert Seed to Earth forcing the Pretty Cures to undergo the ultimate test to gain more power. Cure Marine, Sunshine and Moonlight pass their tests and shortly after the Desert Seed crashes, causing the Desert Devil to be born. The three quickly decide they must battle it without Cure Blossom and buy her time to complete her test. The three manage to keep the Desert Devil busy long enough to allow Cure Blossom to complete her test and all four use their new power, the Super Silhouette. With their new powers from the Heartcatch Mirage they use the Heartcatch Orchestra attack which defeats the Desert Devil and making the world safe.
