About that line of Sora's, I thought he said it because Yen Sid was telling him he had to take the MoM before facing Xehanort. If I were Sora, I probably would have acted the exact same way. To me, the MoM seems like a waste of time when they could be preparing for Xehanort's return. Especially since Sora's defeated him now numerous times. And is doing a lot better than the Keyblade wielders that had years of training.
I'm not arguing with you, but I don't get why people think Sora suddenly thinks he's god's gift to fighting with that one line. You have to remember Blank Points. In that, Sora didn't really seem arrogant at all. More resigned to saving everyone, because it was the right thing to do. He seemed to have really thought the journey over, and is sad to leave Kairi.
IDK. Sora almost seems more mature to me. Especially since he does end up taking the MoM, something he doesn't think he needs to do, to support Riku.
And honestly, Sora's always been cocky. I think that's just how he deals with all the tramua. He passes it off as a joke, and says ridiculous things. Kind of like Snow in FFXIII (though not
as bad, I think). And that's actually why I love him. I love him being light hearted even with everything bad going on.
And at least the line's not as bad as this one from the original CoM, "I'll save Naminé, Riku, AND the king…and I'll do it blindfolded! Heartless? Hah! Forces of evil, do your worst!" LOL.
I think all Sora (and everyone) needs to learn is that Darkness doesn't mean evil, and Light can be corrupt like Darkness can. But that's just my opinion
