Spoiler ShowOn Mickey stuff, the problem with the entire gauntlet section is nothing really happens until Sora gets in. It is clear from their expressions that Luxord, Marluxia, and Larxene were not really trying or not trying that hard. It is a common Shounen thing where multiple fights happen at once, but since the story has to moved from one event to another to keep focus, certain fights just does not really start until the focus is theirs. Sometimes, this lasts for chapters. To say that someone holds themselves against someone for that long is a feat would not really be accurate per say
Spoiler ShowHow do you ascertain a characterâ€™s fighting prowess based on their expressions? And what kind of mental gymnastics do you employ to have that override the simple fact that Marluxia, Luxord & Larxene were all attacking Mickey at the same time â€” which in normal terms, means that they were absolutely trying their hardest otherwise they wouldâ€™ve just took turns to play with him.
To say he held his own for that long would in fact be accurate because that is, by definition, what he did.
For Aqua to have poor treatment, and that actually be problematic; that would imply she had prior treatment that was of the contrary. But it isnâ€™t. Thereâ€™s a reason why no one gives a shit about Aqua.
