_stingers_ posted... Also I haven't played ff7 in 15 years or so and I don't remember any of this Gi subplot, is this new or was this in the original? In the cave they mentioned coming from another planet so I'm guessing they're related to Jenova?
Entirely new, in the original game
they're just regular ghosts, you beat Gi Nattak, see Seto and that's it. I dont recall the original game mentioning black materia's origin either but the original game never addressed materia origin outside of naturally occurring from the planet or for huge materia, the reactor process. I guess the implication in Rebirth is the Gi tribe are aliens? But yeah, I also liked it as a good addition.
