You didn't understand the question. You're making the argument that the difference between them is skill and ability. I'm asking what's to stop Zack from using Ascension? It's a hypothetical question.
I'm unsure of what the point of this hypothetical is. If Zack could use Ascension then that'd make him more like Cloud, I guess?
It's not his technique. It's not his style. You made a comparison between Octoslash and Ascension and I merely pointed out Ascension is the stronger more brutal move given how it targets groups or a single target and ends not just with a downward vertical slice, but an impalement that is followed by Cloud leaping meters into the air, rending the unfortunate target in half, or at least horribly injured.
Zack's swordsmanship is never that brutal or violent, just in terms of attack type alone.
And you're ignoring the fact that Zack's special ability is to copy the abilities of others. Play Crisis Core, and you'll see Zack using Aerith's Healing Wind.
You're right, he can copy limit breaks.
And he never copied Ascension. He died so it never became his to use or demonstrate in battle to measure it's effectiveness. It's not a technique in his repertoire. If it were then it'd be worth discussing and attributing to him, but it isn't.
Anyways, your argument makes more sense as a criticism of his creativity. Not his skill.
I honestly wasn't even criticizing him. It's just a statement of the difference in their abilities and how their techniques are in and of themselves.
You created an arbitrary metric to measure limit breaks just so you could make Zack's look worse. If you're gonna use such broken logic, based purely on perceptual preference, then I could easily counter with the assertion that Barret's Catastrophe is better than Cloud's Ascension because a giant laser is more powerful than a bunch of chicken scratches from an oversized sword.
How am I trying to make Zack worst? I'm merely going by what the game shows and demonstrates here.
You can try to make that argument between the two and that's your choice, and there are maybe some differences between the two limits that would allow Catastrophe to be a better ability in certain situations. However, it would also come down to who's the stronger user in terms of their demonstrated ability and power.
Barret's is far stronger than any normal person, and could obviously handle a SOLDIER 3rd, but I still think Cloud's stronger by Barret's and everyone else's admission.
These games already use their own metric for measuring the strength of an ability. It's called DAMAGE.
That's a very inconsistent and non-scalable metric to measure strength because the damage formula for one game isn't the same for another, likewise the mechanics of stats between characters are highly variable and unique to every player based on their play style, equipment load out and various other factors. Using the game mechanic of damage is wildly inconsistent and inconsequential. The numbers don't exist within the story for one, and it's easily possible to make gimmicky equipment/materia combos that can just distort the narrative.
With the right load out and skillful player, Sephiroth can be overwhelmed and defeated
by Cloud and the others under the toad status.
By your metric, that means Sephiroth is weaker than toad-ified humans.
That's obviously not even close to accurate
Zack fought Genesis multiple times, and beat him multiple times, both as a monster and as a person.
Pretty sure Zack has only fought Genesis twice.
Once in Modeoheim while he was degenerating, and then once again in the final battle in Banora.
Both of which are not normal, measurable circumstances. Again, you're looking at this as some definitive exam to measure performance, like Hojo and the Science Department testing the fitness and strength performance of Zack within the SOLDIER training room. Those fights are not conclusive equalized demonstrations of 1st class talent versus 1st class talent. Genesis being fought in Modeoheim while twisted, mutated and having his life shortened by degeneration isn't the same as Genesis being fought by Sephiroth in the training room while they were sparring.
So you one-shotted Roche? Did you beat him in ten sword swings? Did you beat him in twenty? Did you beat him without suffering any damage?
That's not the only way to demonstrate a character being in control. Look at the scenes and the actual narrative itself. Cloud is clearly shown to be the one who dominated. He's not exhausted, he's completely unphased, and Roche admits his superiority. The bike fight was completely the same. Cloud summarily beat him and disabled his motorcycle. All while protecting Jessie, Biggs and Wedge. It wasn't close, hence Roche wanting a runback.
Would Sephiroth one-shot him? Beat him without taking damage?
Is this a serious question?
Of course he would!
Without a visual representation of skill, such as a cutscene, the best metric we can use for determining skill during a boss fight is by comparing how much damage you do versus how much damage you take.
A cutscene isn't necessary at all, you literally see the aftermath of the battle in the story with Cloud completely unphased, asking if he's satisfied, with Roche having had enough and stepping away. You see Roche's abilities in battle with your own eyes. They're apparent throughout the fight. Roche's abilities consist of some super speed, materia use, and his above-average swordplay. And it's nothing even close to what Cloud can do on his own.
Again, this visual metric you're using only works in a cutscene. How much damage did you take during that fight?
It doesn't matter how much damage I took, the end result is the same, and what does a cutscene have to do with anything? You can't believe what the game's showing you in the very medium you're looking to analyze?
It's a basic rule of storytelling. And guess what, sometimes good storytelling doesn't hold your hand and tell you anything.
If it held such an important role in the storytelling and narrative why is it never subsequently utilized or referenced ever again? Why does Cloud not have it anymore? Why is Zack not even shown to use it or acknowledge it's existence in Crisis Core?
For such an important element in this story, it is conveniently ignored and never brought up again
