Indeed. Sephiroth instead posessed a fragment of "Jenova's superior inteliigence, strength and magic", or whatever words are actually used in the game.Well that's pretty debateable, but either way it was the Cetra in her that let her do magic. Sephiroth didn't have this.
Naturally. Don't you see? Sephiroth was trying to become a 'God', a far higher form of life. Preturnatural abilities are a part of that.But that's the thing, they weren't amplified, they were completely new. Everyone else with Jenova cells got a little stronger, no psychic abilities at all, let alone the stuff 'Sephiroth' could do.He wanted everyone to see that he was back, he was doing his stuff for his own benefit. Also, he had to convince the Clones to come to him with the Black Materia.So then what was the point of making Jenova look like Sephiroth. If all he was doing was guiding it, why did it have to look like him?The Reunion allowed Jenova's body to reform, yes, but it also provided a means of getting the Black Materia to Sephiroth, who was imprisoned in the Northern Crater. He couldn't go anywhere; someone had to get the Materia to him. That's where the Clones came in - he could sacrficice countless of them without any real risk. They could travel, investigate, solve problems, do menial tasks without question. Many of the clones stated their desire to "find it... and bring it to Sephiroth".But the reason for the reunion was to get JENOVA back together, it had nothing really to do with Sephiroth. All 'he' needed was the Black Materia which only required Cloud and Co.Sephiroth is a near-complete fusion of Jenova and Human cells, for moreso than Cloud or the other Clones. He's far stronger than any Human, even before his plunge into the Lifestream, an experience he was able to survive because of his superior endurance. Most Humans would go mad and die because of the sheer amount of raw energy and knowledge down there, but Sephiroth was strong enough to take that into himself and begin his deadly transformation. Cloud had only a little Jenova in him; his Lifestream experience nearly killed him.But the thing is, in VI there was noone else around who could have done it. Jenova had all these powers way before Sephiroth. Both Cloud and Sephiroth experience the same thing, but only one gains these powers, seems fairly odd.I know this is complex, I'm just trying to keep it accessible. FFVI has its own complexity too, you know - in fact, you could argue that Kefka was merely (SPOILER)a mindless puppet under the control of the vengeful Goddesses who wanted their revenge on the world. In fact, it'd be pretty neat if someone were to start that debate in the FFVI forum... sure as heck won't be me thoughI know I shouldn't say this to a Knight, but you may have forgotten given this arguement is fairly complex, you might wanna tag the FFVI stuff..
