Sora also fights monsters on a daily basis (Heartless, Nobodies, Dream Eaters, Unversed, etc) and is regarded as above people that have been formally trained for a decade (King Mickey).
Meh, Luxu has lived for 7 generations as a praised Lost Master and has managed to circumvent the original Darkness that has lurked ever since (with way more hax than the Ectonaurites), yet
was still outclassed by Sora when they fought.
Eh, type 1 immortality is irrelevant for measuring skill, as simply being old doesn't give that stuff and all, please provide feats or something over rather speculative stuff if anything TBH.
Scans please, it sounds more like strategical skill if anything, however, and I'm not sure if this would particularly matter here considering that Sora's powers uh... aren't used like that ever.
Now those are considerable skill feat I suppose, even if only for accuracy.
As for the adaptability, well, I think I've already provided proof in
here of Sora showcasing the capability to adapt to opponents with all sorts of powers, some even mixing them up out of inheriting the powers of other characters.
I'll remind that intelligence doesn't inherently deals with any field whatsoever, especially with how any rating above Genius on the site usually deals more on academic fields than combat, so that's not particularly denotable on its own without feats from the other party on this regard.
Also, something something Sora
has already dealt with "fully non-blockable" sword attacks from Xehanort, who doesn't only dual-wield, but also change weapons on the fly as well, yet Sora has shown the capability to dodge and counterattack accordingly.
The fact Sora can also triple wield also makes him appear to have an higher edge on skill than someone that dual wields at best.
