Suzuran is a Negamonster who works for Zoycite. She can shoot sonic waves. She is one of the plant sisters, and appeared in Sailor Moon Episode 20, A Friend in Wolf's Clothing.
Zoycite sent Suzuran, Housenka, and Grape to kill Neflite. They kidnapped Molly, and Neflite came to save her. He beat them up, but instead of killing them, told them to tell Zoycite that they would not be getting his star crystal.
However, the plant sisters returned to kill Neflite. Before they could kill Molly, however, the Sailor Scouts appeared. After Sailor Mercury used Mercury Bubbles Blast, Sailor Moon and Sailor Mars used Moon Tiara Magic and Mars Fire Ignite, combining their attacks to destroy Suzuran, Grape, and Housenka.
