Nekonnell is a Daimon Heart Snatcher who was created by Kaorinite to extract Pure Hearts. She has the appearance of a humanoid cat. As her daimon pod was implanted in a puzzle, she appears to be made of puzzle pieces whenever she takes damage. Her tail can stretch and she often chokes or whips her enemies with it. She appeared in Sailor Moon S Episode 2, Crystal Clear Again.
Kaorinite made Nekonnell to extract a Pure Heart from a girl who takes care of kittens. Just as she extracted the Pure Heart, she was attacked by Sailor Uranus and Sailor Neptune, who left afterwards despite knowing Nekonnell was still alive. Nekonnell defeated the rest of the Sailor Scouts and strangled Serena (who was unable to transform) with her tail, before Tuxedo Mask arrived to fight her. Just when all seemed lost, the power of the love between Serena and Darien restored her transformation power and gave her the Moon Spiral Heart Scepter, and Sailor Moon destroyed Nekonnell with Moon Spiral Heart Attack.
