No, seriosuly, he's some Sora or shit from the future for whatever reason. Watch Re: Coded's secret ending then speculate.
that's pretty stupid......I think it would be cool if the enemy didn't appear in Kingdom Heart III. Then he remains a mystery and possibly might have something to do with the future of the series. heh... "future".... get it?
If this involves time traveling, how could it possibly be Xehanort? He just came back didn't he? So he learned how to time travel that quick? Even though I highly detest this thoery, it just has to be some form of Xehanort. After beating MF, you see how he looks down as if sad or something and then vanishes right? Maybe the battle gave him memory of Aqua and afterwards he may have remembered who she was. But maybe thats why theres no dialogue. With Enigmatic words, we the players can't hear the voices, but the characters can. So if it's Xehanort, of course Aqua wouldn't know it at first, but when she fights Terra-Xehanort she would be like "Either I fought you earlier or it was somebody who sounds exactly like you." Wow that's stupid, I'm done...
