The Sephiroth Ghost

[Dragon Mage]

yesh, Big D nailed it in one.

How else do you think the Remnants came to be in AC?

In Cloud's final battle with Sephiroth he shattered the 'will' of Sephiroth's spirit, which was controlling Jenova's body. Sephiroth's spirit, you see, never merged into the Lifestream because he resisted it via power of will.

When Cloud shattered that spirit, the remains became the Remnants. Again, the Remnants were just parts of Sephiroth's spirit in Mako colacecsed into material form, all pulled together by the power of will.

yarly!

The SHM are bodies formed of tainted spirit energy(the Negative Lifestream Sephiroth used in the end of the movie) and part of his will(to make them find the J-cells).

The reason why I thought of this theory is because of Aeris and Zack ghost appearances. They all could be linked. There's no actual proof that the appearance of Aeris has been incorrectly programmed in FF7.

Cloud may or not have been injected with J-cells, explain why he could be able to see Aeris and Zack appearances? If it was only Zack, not aeris... it would make sense but why Aeris now?

Ghosts are rife in FFVII. There are ghostly monsters in the Sector 7 train graveyard. The spirit of Elmyra's husband tried to visit her after he died, but returned to the Planet before he could get to her. The Gi Tribe were trapped in this world after their defeat, and their spirits lingered in the cave behind Cosmo Canyon. When the Black Materia needed to be guarded and the knowledge of its existence protected, several Cetra chose not to return to the Planet, and remained at the Temple of the Ancient in the form of 'spirit bodies'.

Then there are the guys from the training facility in Sector 7, killed when the plate fell but unable to return to the Planet because of their unfulfilled desire for knowledge, hence their appearance in the Respectable Inn in Junon. I mention them separately, as they're perhaps more of a joke/tutorial tool rather than actual characters.

My point is... Something?
Oh yeah. Ghosts, or spirits that haven't (yet) faded away, aren't exactly unknown in FFVII. Aerith's ghost is the most talk-about example, even if it appears prematurely due to some sort of glitch.

Yeah, I guess that's a good reason why one of the graphic designers have added the Zack's ghost to the AC photo in near of the end.
