Neifirst

"Yes, that's the one you call Nei. The one you think is a friend is a monster that despises people!"

- Neifirst

Neifirst is a major antagonist from Phantasy Star II.

Story
Neifirst was the very first of the Newmans, a race of genetically-engineered beings created with the combined DNA of humans and animals. The experiment which resulted in the creation of Neifirst was deemed a failure, however, so the scientists who created her attempted to dispose of her, but she escaped and decided to get revenge not only against her creators, but also on all humans. However, a part of her being was trying to stop herself from causing harm to others, so she separated herself in two, the evil Neifirst and the good Nei, whom she left behind. Nei would be later rescued from a bandit by the protagonist Rolf, who adopted her as his own sister.

When biomonsters start plaguing Motavia, Rolf is sent on a mission to investigate the cause, taking Nei along when she insists on accompanying him. During his mission he would also be joined by other people, each for their own reasons. Upon investigating the Biosystems Laboratory, from where the biomonsters were being created, Rolf learns that someone had hijacked the Climatrol, which controlled the weather on Motavia, siphoning all of it's energy into the Biosystems lab for the creation of the biomonsters. Making his way into the Climatrol, he finally finds Neifirst, who reveals Nei's true origin and her hand on hijacking the Climatrol. Nei attempts to stop Neifirst by herself, but ends defeated in the ensuing fight, dying on Rolf's arms. Enraged, Rolf promises to avenge her and attacks Neifirst along with his comrades. Though Neifirst is defeated, her death causes the Climatrol to go haywire, flooding the entire planet with all the rainwater which was stored on the facility.
