All of the fighters of the Dark Fall had been beaten by the PreCure, and returned to their native forms. But starting in episode 41, Gooyaan used the power of the fairy carafe to "recycle" the fighters.

All of the recycled fighters had a little Gooyaan mark somewhere on their bodies. They were stronger than they were in their original forms. The recycled fighters didn't create any monsters, and just fought the PreCure and Michiru and Kaoru by themselves.

The recycled fighters were eventually beaten by the PreCure and Michiru and Kaoru. Michiru and Kaoru used a blast to knock off the little Gooyaan mark from the fighters. This reduced the strength of the figthers, and the PreCure finished them off with their blast.
