User blog comment:UberRat35/Why doesn’t Daisy count as a new fighter?/@comment-32618542-20180708031940

Daisy is officially Peach’s Echo Fighter, as she fights just like Peach, even if Daisy has Blue Toad and her “Flower Power”, while Peach has the original Toad and her “Heart Power”. Anyway, the point is Daisy is a clone of Peach, therefore she’s Peach’s Echo Fighter, at least that’s what Sakurai said.
