Sephiroth is definetly stronger. Especially in Advent Children. Though Genesis is powerful as well.
the producers of the game say that sephiroth is stronger, and you can't really argue with the people that made it :I
No.
Yes, as Project S, which created Sephiroth, was completed shortly after Project G, which first created Genesis and then Angeal following him. To put it simply, Genesis is the eldest out of the three, and Sephiroth is the youngest. The age gap is probably around nine months or so, I'd imagine, or shorter.
Kind of. Sephiroth's best friends were Genesis and Angeal; he was a little cold to everyone else, including Zack. After Genesis and Angeal left Soldier, Sephiroth and Zack became acquaintances and got along with each other pretty well.
Sephiroth.
Beat Sephiroth also its Cloud's sword you get not Sephiroth's
Sephiroth's birthday is unknown. Of course, Sephiroth was never technically born.
I believe only twice, Safer-Sephiroth, the first form and regular Sephiroth, the battle where Cloud beasts Sephiroth with his overlimit.
Genesis and Angeal having wings in Final Fantasy Crisis Core is never exactly explained. It is believed to be due to them being experiments of Project Jenova as they were born in a similar way to Sephiroth.
Cloud is a 'Sephiroth Clone', but not a clone of Sephiroth. In game terms, a 'Sephiroth Clone' was simply someone injected with Jenova's cells, and who Sephiroth was able to control indirectly due to his own link with Jenova. It does not imply they are a clone of him, in the traditional sense of the word.
No. Just No. Sephiroth is to purely awesome.
Sephiroth is voiced by Lance Bass.
