KH Tarot: The Devil

Card # 15 - The Devil. Also known as The Lord of the Gates of Matter or The Child of the Forces of Time. It shows Prince of Darkness himself sittning on throne with two of his chained servants.
Meanings: feeling the burden of the material side of life; desire for physical and material things. Feeling of frustration and oppression. Lust. Sexual obsession (?!). The querent's knowledge of his or her own needs, wants and desires. Security versus creative or spiritual fulfillment.
Reversed - true evil. Abuse of authority. Material success is the focus to the exclusion of all other things. Uncontrolled ambition. Greed. Bondage to a person or situation or thing.
Why I choose Xemnas? Ansem (Xehanort) also could be a good choise. But I think above all of them Xemnas is more evil. He is that kind of villian without any good qualities (excepting his unsurpassed hotness, of course!)
