He's a Sephiroth clone I created after the real Sephiroth died five years
ago. Jenova cells and Mako, with my knowledge and skills, have been combined
with science and nature to bring him to life. ...I'm not wild about the failure
part, but the Jenova Reunion Theory has now been proven. You see, even if
Jenova's body is dismembered, it will eventually become one again. That's what
is meant by Jenova's Reunion to start. Five years have passed, and now the
Clones have began to return. I thought the Clones would begin to gather at
Midgar where Jenova is stored. But my predictions were not entirely correct.
Jenova itself began to move away from the Shinra Building. But being a genius
that I am, I soon figured it out. You see it was all Sephiroth's doing.
Sephiroth is not just content to diffuse his will into the Lifestream; he wants
to manipulate the Clones itself.
