I disagree with Axel being stronger than Marluxia. I don't need to bring quotes of CoM,
and how Riku, or was it Sora, sensed a "great power" defeated. Or I believe it was when Sora reached the final boss Marluxia when he stood in the front door that he mentioned what's behind. Whichever the case, Axel never got that tidbit, now, did he? Not to mention what Marluxia can do far exceeds what Axel can. In a lot of ways.
If you're talking about the spar, it didn't really proclaim anything. None used what they were fully capable of. In fact, all they did was jump around and clash weapons. And from what I saw, it was Axel who was struggling and going on defense.
On top of the fact that we don't know WHO was the main conspirator for Castle Oblivion, or what was the plan, and what went in there, that doesn't really help the argument. Axel depended on using other people. Not defeating any of the members themselves unless they were weakened.
Vexen has more pride than anyone else. It's about how well they do. They can change it, yes, but they do it accordingly.
The pride thing was more of examples. Nomura said it's their choices, and what height they want it to be. Not how well they do. And I'll take that word. If that was the case, some of the powerful members would be higher.
It applies to the Organization is well. The chairs after the mission are just for fun, but the rules still apply in where nothing gathers.
There's no such fact of that rule.
