Tesuni

Her signature prop is a racket woven from fire and energy that cradles a black ball at its heart. Blonde hair frames pale, near-white skin, and she wears a near-black uniform in dark blue accented with gold bracelets. A red pendant sits at the middle of her chest, while a red collar piece drapes across her shoulders.

Nephrite plants her essence inside Rui Saionji's tennis racket as part of his campaign to harvest energy for the Dark Kingdom. Once the girl's reserves peak, Tesuni surfaces from the racket and begins draining her dry. Sailor Moon rushes in to save Rui, only to be sealed inside a huge tennis ball. Tuxedo Mask arrives and rattles the monster with a strike from his cane, buying the moment needed to release Sailor Moon. When Tesuni moves to attack again, a thrown rose catches her in the face, and Sailor Moon seizes the opening to destroy her with Moon Tiara Action.

Even before fully emerging while still lodged in Rui, she funnels wind through the racket and whips it into a gust strong enough to fling Usagi and Naru aside, knocking the latter out cold. Her core weapons are tennis balls of pure energy: a single hit encases Sailor Moon's torso in a giant ball, leaving only her head and limbs free, after which Tesuni floats and bounces her around the court at will. Balls that miss detonate on impact, and she can also spit fire in sizes from small spheres to massive blasts, one of which comes close to killing Usagi.
