Petasos

Petasos was a Youma owned by Nephrite. Her essence was implanted into the hat of Kunitachi, the caretaker at a local park that was scheduled to be demolished to make room for a business complex. Petasos gave Kunitachi the power to control the animals at the park, allowing him to drive away the construction crews and protect nature, but every time he drew upon the Youma's power it caused his energy level to rise. When it finally peaked as he confronted Ami, Usagi, and Luna in the park, Petasos drained his energy and emerged from the hat.
