Well that works for the Vanitas battle, but this guy has blue sabers. Which have a different design if you look closely, meaning this character is new and *could have a role.
If we all think back to KH2 FM+, the speculations about that canon were about the same.
You didn't read my post very clearly.
I said the BATTLE being non-canon. The character is canon, that's obvious, but the battle itself could just be non-canon.
