Petasos

Her skin carries a lavender tint, and in place of ordinary hair she grows a tangle of green vines, with leaves budding at both her wrists and ankles.

Nephrite sets his sights on Mr. Kunitachi, the caretaker of a park slated for demolition, judging the grieving man an easy source of energy. Posing as Masato Sanjoin, he plants Petasos's essence inside the man's hat and grants him the monster's power to command the park's animals and insects, though every use pushes Kunitachi nearer to his energy limit. He turns swarms of butterflies loose on the demolition crew and on a park official before his reserves finally peak, letting Petasos burst from the hat and drain him dry.

She then bends the local wildlife to attack every human nearby, including Usagi and Ami, who become Sailor Moon and Sailor Mercury. Mercury's Bubble Spray blunts the assault, but Petasos ensnares Sailor Moon with a flower-launched net and coils her hair-vines around Mercury to crush her. Rei arrives, transforms into Sailor Mars, and burns the bindings away with Fire Soul. When Petasos lunges once more, Tuxedo Mask stuns her long enough for Sailor Moon to end her with Moon Tiara Action.

Petasos fights with a pair of named techniques, a rarity for a monster of the day. Her Petasos Rope sends the vine-like strands of her hair to lash and constrict a target, while her Hand Flower fires an enormous bloom from her palm that bursts into snaring vines; deploying both palms at once turns it into the Double Hand Flower.
