Fusion is the main antagonist of the Pretty Cure All Stars DX movies Pretty Cure All Stars DX: Minna Tomodachi - Kiseki no Zen'in Daishuugou! and Pretty Cure All Stars New Stage: Mirai no Tomodachi. As his name suggests, he is a fusion of the vanquished Zakenna, Uzaina, Kowaina and Hoshina and has the ability to absorb power and make it into his own.
Pretty Cure All Stars DX
Fusion made his first real appearance in this movie, demanding the need for power. He split himself into four parts, and attacked the Pretty Cure. When the Fresh Pretty Cure drove off one part, it reappeared in the Palmier Kingdom, driving off the other Mascots there and attempting to absorb Chiffon. However, the power of the Miracle Lights ended up destroying the piece. The other three pieces encountered the other three Pretty Cure teams, absorbing their strongest attacks before uniting into a stronger form which the Fresh team encountered first. He attempted to absorb them before the power of their unity freed them, though they believed that the other gathered Pretty Cures did so.
The tide was turned when Chiffon reappeared, holding one of the Miracle Lights. The other gathered Mascots, in turn, used the Miracle Lights to empower the gathered Pretty Cure, allowing them to destroy Fusion once and for all.
Pretty Cure All Stars New Stage
Fusion was to return as the main villain of Pretty Cure All Stars New Stage: Mirai no Tomodachi. After the story of the previous movie, a piece of Fusion survived the battle and was left as a mascot-like character, known as Fuu-chan in this story. After meeting Ayumi Sakagami and becoming her friend, he wished to help her by resetting the world, and became his full self again. Yokohama's Minato Mirai is once again thrown into darkness.
- A beast that resembles Fusion appears in Pretty Cure All Stars: GoGo Dream Live, though without the Hoshina component.
- As the first DX movie aired on the early stages of Fresh Pretty Cure, Fusion does not include the Labyrinth's Nakewameke amongst the monsters he could conjure.
- Fusion is similar to Noise from Suite Pretty Cure♪, both having an alternate form (Fuu-chan & P-chan) and getting along well with a Cure (Ako & Ayumi) before destroying the Cure's precious things (although unintentionally in Fuu-chan's case as he was just trying to help Ayumi).
