Nettori is the seventh boss faced in Super Metroid, being the very garden of SR388 brought to life when infected by the X Parasites.
After Samus intercepts Sector 2, the tropical site of the Biologic Space Laboratories research station, she watches as the family of plants she stands in evolves into a hostile creature, Nettori. Nettori will then begin to attack Samus with flowers and plasma beams, but can be easily defeated with power bombs and ice missiles. After defeating Nettori, Samus gains the plasma beam to assist her on her mission.
