If Tifa and Aerith fought...

[Ryushikaze]

They look identical to regular humans but possess a unique ability to commune with the planet and to guide the flow of its spiritual energy. All ordinary humans can trace their origins to the Cetra, having ceased to become Ancients when they gave up their migratory life-style and link to the earth in favor of permanent settlements and a more relaxed way of living.

Repeat after me: Wikipedia is not a source.

Or rather, that Aerith is the only one capable of hearing the planet (which she canonically isn't, mind. Bugen comes to mind), if their abilities are genetic, seems incredibly unlikely.

Bugenhagen is not a Cetra. Otherwise he would have been imprisoned by Shinra, or certainly would have tried to use Holy, instead of giving Cloud and co. advice:

Bugenhagen: Holy... the ultimate White Magic. Magic that might stand against Meteor. Perhaps our last hope to save the planet from Meteor. If a soul seeking Holy reaches the planet, it will appear. Ho Ho Hoooo. Meteor, Weapon, everything will disappear. Perhaps, even ourselves.

Cloud: Even us!?

Bugenhagen: It is up to the planet to decide. What is best for the
planet. What is bad for the planet. All that is bad will disappear.
That is all. Ho Ho Hoooo. I wonder which we humans are?

Note I never said Bugen was a Cetra. Though it IS worth noting that your Bugen quote comes from him y'know, listening to the planet in the cascade.

Being a major plot device, the White Materia cannot be equipped or used in battle, and technically does not exist as an item at all in the game engine.

Repeat note regarding Wikipedia, also, relevance?

Aerith: Only a survivor of the Cetra, like me, can do it.

Yes, Aerith thinks she's the only one that can use it. She's not omniscient. Excuse me for not thinking the Cetra are complete smegheads and placed a ridiculous limiter on their override/ abort device.

1. I'm sorry but thats rubish, we arent talking about the movie where battles are set in Real Time we are talking about a battle inside the game where the battle would be Turn Based so the battle would go somthing like this:

FF7 uses the ATB system, but that's somewhat beside the point. Why are you using a gameplay engine we know to not fully represent combat as somehow more comprehensive than actual combat? No, really. Do tell.

Tifa: attack
Aerith: Fire (or some other magical spell)
(and say for instance Tifa is faster as you say maybe she would get 2 turns thus filling up Aeriths limit bar that much faster.

Well, if Aerith gets magic, why not Tifa? They both use materia to get it.

half way through the fight Aerith uses Great Gospel and she is now invincible
Tifa: FINAL HEAVEN!!!!
Aerith: takes 0 damage
Tifa: "Oh crap"

Now Aerith can try damaging Tifa until GG wears off. That will be fun. Of course, Atlanteay's point is also valid, especially if one uses the godhand/deathblow combo.

4. I'm sorry but thats a load of Bull, Aerith is recognised as the mage of FFVII and as such she would be a mage in any such D&D comparison, its just the fact that practically no one used her as a mage its their loss.

She may be 'recognized' as the mage, but that hardly makes her one, especially since she only has healer spells sans materia, making her actually more akin to the obscure 'healer' class than anything else.

so your saying that in a turn based battle with Tifa at lets say for arguements sake they are level 30 both that she could kill Aerith in 1 hit? dont be stupid of corse she couldnt, while she would have the greater physical stats Aerith would have greater magical stats and would do much more damage with her magic.

This has absolutely nothing to do with my tangent, but yes, Tifa can 1HKO Aerith, with Godhand/Deathblow. And the amount by which Tifa's physical stats outclass Aerith's is higher than the amount by which the reverse occurs.

lets not go down the road if and but's, Aerith did have holy and she was the only one who could have used Holy. Full stop.

She had Holy. She was not the only one who could have used it.

Well the 2 things you said are completely ridiculas its like saying how do we know that Bruce Lee could kick some 10y/o's ass: its just somthing that you know just as the same that we "just know" that Barret cant do quantum physics and that Cait Sith cant arm wrestle the Proud Clod it possible that Aerith can move fast if she has such a need to.

You miss the point. My two examples have never even hinted at having that capability. Similarly, Aerith has ALSO never hinted at being able to move at high speed. Especially in a critical situation.

Holy was useing Aerith? iv never heard such a ridiculas thing in my life, Holy is a materia and materia dont "use" people its the other way around Aerith used holy. Besides the Cetra were powerful magical beings, thats how Materia was made:

Cloud: By the way… Why is it that when you use materia you can also use magic
too?

Sephiroth: You were in SOLDIER and didn't even know that? …the knowledge and
wisdom of the Ancients is held in the materia. Anyone with this knowledge can
freely use the powers of the Land and the Planet. That knowledge interacts
between ourselves and the planet calling up magic……or so they say.

Thank you for proving my earlier point. However, Holy WANTED to be cast, since Meteor had been, and its purpose was to counteract it. People use materia, but when the materia wishes to be used, the dynamic changes slightly, would you not agree?
