Hello KH13 I have a interesting theory I like to share. I always thought Luxu would be a bad guy since xehanort keyblade is luxu's. But since cut scene's of back cover, he doesn't seem so bad. In fact he may not be bad at all. Looking at my perspective, He really cares about the others(unless shown in back cover), and doesn't want them to dead. But nothing he can do to stop it. Here is where the theory kicks in. The Master of Master's saw the massive potential of darkness in Luxu. Kind of like he seems to kind for his own good, So M.O.M. in my opinion used the Keyblade factions(Well the Masters), and rip the page to cause frustration amongst the Foretellers. M.O.M. then told Luxu to watch the Keyblade War and watch his friends get smoked. This will cause his darkness to rise after the events. Possibly it said that it's the first Keyblade in existence, His darkness will be so great it will corrupt the Keyblade with his will. Now X-BLADE was in the war. Now the box shown in back cover could be the pieces of the X-blade. Now this is the best theory I got till January 12th(Japanese release). So I hope you like it guy's.

It's not a bad theory but I'd say maybe the darkness rises inside of Luxu because the M.O.M. lied to him about his original plans . I guess we will just have to wait and see.

Yeah, your theory could definitely be spot on! I was also ready to see Luxu as this menacing villain, but the way he sounds in the trailers makes him seem like he's actually quite a sensitive, nice guy! We'll just have to wait and see what he and the Master Of Masters eventually do in Back Cover!
