Zexion's Weapon Discussion

[Muse]

... Marluxia has a scythe. Zexion has a lexicon.

The only hypothesis I have for his weapon is that he has none. He is a replicator, a being who has the ability to clone or replicate things using his own physical anatomy. If you remember what started the fight, he disguised himself as Sora, and the keyblade became his weapon as of doing so, but when the fight started he began using the Soul Eater. Also, if you look at his grave in The World That Never Was, The picture of his weapon was completely destroyed while the others were somewhat intact and able to see. As of the fact of Zexion using a lexicon that is possibly the most accurate way to explain it.

His power is illusion.
His weapon is the book.

This is better seen in FM, where he actually attacks using the lexicon.

He doesn't really USE the Lexicon, he's actually just sending book at you :/

Since Zexion's weapon was revealed long ago, there's no longer any need for this.
