ssceles:

Just throwing this out there for anyone who’s slow to catch on (or easily distracted by Nomura throwing us one bone and sweeping another under the carpet):

Between the anagrams in the names of the Organization XIII members and Nomura under-handedly teasing us with the No Heart boss battle that only came in the Final Mix edition of Birth by Sleep in Japan, we know Xehanort’s name is looking a little suspicious. 

Yes, all the letters in Xehanort can spell No Heart (and ‘No Earth’ but really, that was never significant to me).

But all the letters in Xehanort can also make the word Another. And read as Another X… or, say, Another χ…

I know we were handed “chi” and “kye” but it was also handed to us as “key”. Given that… his name is very literally “Another Key”.

And if that isn’t mind blowing enough, think about what that could even mean in the context of the series.

Additionally, it might interest you to know that in KH2FM, Xemnas enters passwords into a computer terminal at Hollow Bastion before visiting Aqua’s armor. The word typed in first was ‘Another’ (followed by several passwords of lengths long enough to be the apprentice’s names – and of course, we know he shoved X’s into their names and created anagrams of them).
