Tellu (テルル Teruru) is the green-haired member of the Witches 5 with a rank of Level 404 and able to use the "Mandragora Buster" attack, named for the mineral tellurite. She acts under the alias of Lulu Teruno (照野留々 Teruno Ruru) and is prefect of Mugen Academy's Physical Education class and Botanical Garden, providing a number of her artificial Telluns plants to the populace to absorb Hostes from their victims. Though her scheme is found out by the Sailor Guardians as they confront her, Tellu overpowers the Sailor Guardians before assuming her Daimon form to finish them off. But Tellu ends up being killed by a newly re-awakened Sailor Pluto. When Kaolinite revives the Witches 5 for her curse against the Sailor Guardians, Tellu targets Jupiter's insecurities and later attacks Sailor Moon before destroyed by the Outer Guardians.
In the first anime, after deposing of Mimet, Tellu's role is slightly different as she opens a flower shop to sale her Telluns before being confronted by Sailors Moon, Chibi Moon, Pluto, and Tuxedo Mask. When her Telluns being destroyed, Tellu mutates the last into a Hyper-Tellun to kill the group. But Tuxedo Mask hurls one of his roses at Tellu and causes her to lose the Pure Heart Crystals she gathered, resulting with her being attacked by her own creation. Tellu electrocutes the Hyper-Tellun in an attempt to break free, but it self-destructs and she is consumed in the explosion.
