If Tifa and Aerith fought...

[Ryushikaze]

I don't need to, because you still haven't offered any evidence that anything quoted from Wikipedia is wrong.

And you have provided no evidence that your claim is correct. Burden of Proof and such.
And would you like to know why Wiki is worthless as an authoritative source? 1- It's a third hand source, at best. 2- Anyone can edit it. Leading to 3- When controversy arises the moderation staff is more concerned with compromising and 'non partisan reporting' than with actual accuracy. Besides all this, if you want to tell me your third party source is accurate, show me the first party passage they are citing.

In the statement you're trying to disprove, "unique ability" means that no non-Cetra in FF7 is born with the ability to listen to the Planet. Name one non-Cetra that was born with the ability to hear the Planet. Please.

An interesting, if ultimately worthless, goalpost shift, since the statement doesn't actually say that. It doesn't even MENTION the word birth. Nice try though. Don't do it again.

Exactly. And how did it get in Aeris' hair? Ifalna gave it to her. Why not give it to someone like Bugenhagen? Because she knew that only Cetra could use it.

Or because Aerith was her daughter, she gave it to her in an emergency, and/or didn't know Bugenhagen. I mean seriously. Your non sequitors are getting more and more ridiculous. Care to provide evidence for your assertion? Didn't think so.
Ilfana, BTW

My source is the people you mentioned in this quote:

Do I have to repeat my request that you explain how it not being battle equippable means no one can use it? For the longest time, people claimed only Sephiroth could use Masamune, when the canon evidence of Tifa picking it up and swinging it at him is right in front of them?

So your "source" is mindless fanboys. Check.

Also, the instruction manual says "His giant sword which only he can handle". Masamune is the name of his sword because almost every Final Fantasy game has a sword named Masamune. It is not meant to have a history behind it. If I'm wrong, and if it was forged by the wutai, most likely Shinra authorised the sword for Sephiroth's use. It is not relevant, you brought up the Masamune using the above statement.

I brought it up as an example of people having stupid unfounded brainbugs, like the WM brainbug. I'd also like to note that, again, you've cited a 'source' that is directly opposed by the canon, and the canon wins that battle.
Addendum: "It's not supposed to have a history" is begging author's intent, and means you Fail Suspension of Disbelief 101. Though it does bring up the question- Why would Wutai build a sword for the star soldier of their enemy in war?
Please do not use this aside as an excuse to avoid answering the primary point, as you did before.

-snip the game script-
Two things I worked out from that passage:

1) The Black Materia can't be used unless you have great Spiritual energy. No one person has enough. You need access to plenty of the planet's energy, a.k.a. the Lifestream.

Well, grab me a Mako reactor and let's cast us a deathmissile.

2) Sephiroth gained the knowledge and wisdom of the Ancients from travelling the Lifestream. That is when he started his plan to use the Black Materia, which was what I meant to say. Note my post never says he learned to use it in the Lifestream.

Sephiroth, and only Sephiroth, could use Black Materia because he spent years in the Lifestream, and so gained all the knowledge of the Ancients.

QED. Again, however, still bears out my "It is knowledge, not genetics, that allows one to use the damn thing"

Except for White and Black Materia. They are very different to normal Materia. Do some research.

Show me some evidence, instead. You claim Meteor and Holy require special activation. Prove it.

I believe it was you who said:

Disagree. Holy was using Aerith to be cast, Aerith just went along with it.

Name one other Materia that does that? I'd call that special activation.

A big glowing Neon "CAST ME" isn't special activation, though I will admit I was too anthropomorphic in my original description.
Alright, let's put this simply- the White Materia is an OVERRIDE/ABORT device. That means its purpose it to counteract the Launch of our superweapon, the Black Materia. It's like the shut down code for a missile launch. If you insert it before the missile is ready, the system still processes it, but since the conditions are already where the shut down is supposed to arrive at, no overall effect occurs. However, once the Black Materia is loosed, you now have the preparation for missile launch in place, with the missile on the table. From this point on, up intil the launch of the missile (and possibly even a few seconds afterwards, before it gets enough thrust), the shut down code will work, since its purpose to change a ready state to an abort state, is now possible to be completed. Holy wanting to be cast, in this analogy, is the equivalent computer AI saying "XX:XX until launch. Please insert shut down code A32"
To use another example of why Using Holy in the wrong situation results in nothing- You cast revive on a living party member. You succesfully cast, but nothing happens, because that party member is already in the state revive is supposed to restore them to.

Because Aerith knew nothing of Holy until she got to City of the Ancients, she said that because the White Materia, when calling to her, told her that. Aerith may not be infallible, but the Planet is.

But she wasn't at the city of the ancients when she sent the message. So she's not been told that information yet, by your argument.

Yes she was. She sent that message, according to Cloud's words, "after I handed the Black Materia to Sephiroth", so even if she wasn't there, she was still being led by WM.

Can you even keep consistent with your argument? You said she didn't know anything about Holy til she was at the city of the ancients. I point out that the message was sent before she arrived. And now you're saying that she knew because the White Materia was leading her, despite just a moment ago, in WHAT I QUOTED, you were saying she knew nothing til she arrived.

Aeris was there much longer. It was a joint Effort between her and the WM. She was "Chosen" so to speak.

It's very similar to how Sephiroth was situated in the Crater - the only difference is that he doesn't have the materia yet.

This is all I'll say for now as I'll make the thread go off topic if I do.

So make another Topic and provide some evidence for your claim. Please note the importance of the second half of the first sentence.
