What Level is Aqua by KH3?

Debated whether to put this here or the Spam Zone, but I think there's some legitimate discussion to be had here.
Aqua has been trapped in the RoD for a while now. We don't know how long, what we DO know is that she was trapped there fighting super powerful heartless, and that she has a keyblade the strength and length of Ultima Weapon.
So she must be REALLY powerful by the time Sora or whoever finds her, right? Like surely by now she's beyond Firaza or whatever KH's most powerful fire magic would be... or will she be?
I think the only way the story will make Aqua super powerful is if for whatever reason she is a boss fight when you meet her. Otherwise she'd probably need a contrivance to be less important than Sora and Co.
Probably something like the darkness weakened her or something. Or they could say she and her skills atrophied with the time... but that might be a bit too real for KH

 

I never thought of levels as objective power levels, strength, or skill. I always thought they measured experience and familiarity with combat, which would explain why some characters start over at Lv1—They spend time away from their training and have to relearn when the need arises. So if she's constantly fighting for her life, I'd say she'd be a comfortable 100; but if she's found safe places then there's no telling.

 

Riku vs Aqua would be weird, now that I think about it... Riku has a lot of Aqua's abilities for no reason.
People say that Aqua would confuse Sora for Vanitas and fight him, but that's not the case. Nobody but Ventus saw Vanitas' face

 

It's not like Riku was a master when you played as him, and it doesn't really explain why they can both double jump
