“There’s no value in betting on something in which the outcome can already be seen.”

An organization member with the disposition of a gambler who always enjoys challenging a win or lose situation, even if it’s betting on life or death.  He keeps his hair and beard extremely neat and no matter the situation he’ll always show that he is keeping his cool both verbally and through his actions.  He decided to take on Sora 1 on 1 at the organization’s castle, but ended up being defeated and vaporized.

[2]He is a gentleman towards anyone he comes in contact with and keeps calm, showing there is no pressure on him which seems conceited to others.  At Port Royale he utilized the pirate’s code in order to make things more difficult for Sora.

[COM]Although using Namine’s abilities in order to manipulate Sora was initially part of the organization’s plan, Marluxia intended to make Sora a pawn of his own.

[COM]He appeared in front of Sora while Sora was seeking the King and Riku, and ended up inviting and persuading Sora to go to Castle Oblivion.
