Great Demia

is a villain in that appears in Kamen Rider Ghost: Final Stage. It is an A.I. version of the Demia Project, which managed to stored itself in another server.
==History==
Sometime after Takeru Tenkuji stopped the Demia Project, though the main server of the project has been destroyed, its data was revealed to be also backed up into another server.
In a possible future, the project was restarted and gave rise to the mysterious Great Demia. From there on, it sought to replace humans and take over the world. It was responsible for the alleged death of Takeru Tenkuji, leaving his son Ayumu to succeed him as Kamen Rider Ghost.
As the second Ghost was becoming a nuisance in the Great Demia's activies, it decided to travel to the past and kill the Takeru from that era to prevent Ayumu from being born and resurrected the Gammaizers. It was faced off the Tenkuji three generations, before defeated by their Byakko-Son Grand Bomber finisher. After returning to the future, Great Demia was eventually defeated by Ayumu once more.
