And I didnt say his weapon was ON his arms or hands and neither did Famitsu. I said that his weapon IS his arms/hands. But I see what you mean, when i said a specific power could be ON it. Well, why do you think it would be hard to do? In fact, it would be easier, seeing as they don't have to make an entire weapon...
Ok dude, you need to stop with the hands/physical theory.
Nomura said his weapon would be revealed in a scene.
How would you even know it's a weapon if it's just his hands glowing? That's not really the kind of weapon you'd think of.
Instead of the Soul Eater, Nomura said he has his own weapon, you would think of something with a handle like a sword. Besides, how are you going to put hands on his grave? I guess they could, but it's just not what you'd expect, right?
"A" weapon isn't hands. "Weapon's" would be his hands.
"Definition of weapon: A weapon is any tool or object that is used to increase the destructive range or power of a human."
and why should this guy be so Important that he would come back in KH3? To pick up his kick in the ass?
Maybe because Zexion is the nobody of Ienzo, the one who persuaded Ansem the Wise to continue his experiments.
He may have importance, perhaps something to do with who opened the door in Ansem the Wise's castle.
