Zexion Cosplay Wig

Appearance

Despite being one of the Organization's founding members, Zexion physically appears to be the youngest of the group, and is certainly one of the smallest in stature (save for Roxas). He wears the signature black Organization cloak, boots, and gloves, though his cloak's sleeves are slightly bell-shaped. Zexion has bright aqua colored eyes, though only his left one is clearly visible, the right one being covered by his long, layered bangs. His steel-blue hair (appearing more grey in the Gameboy version of Kingdom Hearts: Chain of Memories) sports messy bangs that completely cover the right side of his face, reaching about an inch or two past his chin. On his left side, his bangs, though still rather long, are shorter than the right side, partially covering his ear. A few strands of hair fall over the exposed section of his face. The back of Zexion's hair is quite a bit shorter than the front.

Personality

Zexion is sometimes seen smirking or grinning, something he and Larxene share. Unlike the other members, he conducts his tasks in a veil of secrecy, suggesting an enigmatic sort of persona. Zexion apparently also holds a fondness for literature and the humanities, which is noticed in the weapons he utilizes and his manner of speech when speaking to other members. It was most notable in Kingdom Hearts 358/2 Days when he had assisted Roxas in his tutorial mission, thoroughly explaining details in a polite fashion. Another instance of this is the name of one of his Lexicons, the Heretic's Memorandum. His approach to dealing with his enemies; namely, he does not fight them outright, but uses schemes and illusions to bring them down. He wields "illusion" but originally did not show his weapon in Kingdom Hearts: Chain of Memories.

His weapon panel in the Proof of Existence (an area of the Castle That Never Was displaying the Organization members' weapons and titles) is shattered in Kingdom Hearts II, but it is revealed in Kingdom Hearts Re:Chain of Memories that his weapon is, in fact, a Lexicon, which attacks through a flurry of pages and trapping people within it. Like Riku, Zexion has the ability to identify the "scents" of others, with great accuracy and at great distances. The "scent" he smells may be based off other things than mere odor, and is affected by presence of darkness in the heart, an entity's power in the castle, and other factors.

Zexion stands out in Kingdom Hearts: Chain of Memories as the mastermind behind the actions of those members who are actually loyal to the Organization. He is aware of the Organization's decline, calling it "deplorable". Zexion also takes his missions seriously (In contrast to Demyx or Xigbar, who do not.)

Of the three senior members (the other two being Lexaeus and Vexen) with the lowest thrones in their meeting chamber, named "Where Nothing Gathers", he seems to have the highest, while Vexen's is the lowest, indicating he is the most competent of the three. That is certainly not untrue, as he is the mastermind for the plot chronicled in the Reverse/Rebirth storyline, which only failed through Axel's betrayal of both sides; Axel's betrayal of Marluxia, by releasing Naminé, caused a chain reaction, as it was Naminé, in the guise of Kairi, who assisted Riku in breaking free of Zexion's trap in the Destiny Islands, which caught Zexion off-guard. Immediately after, Axel himself appeared and had the Riku Replica kill Zexion.

The fact that he acts as the mastermind behind Lexaeus and Vexen shows that his rank in the organization may in fact be higher than his number would lead one to believe. This is further reinforced by an additional scene in Kingdom Hearts II Final Mix where he is seen to have a conversation with Xigbar. He reprimands Xigbar's habit of eavesdropping, and even talks down to him, stating that he should get back to work. When Xigbar informs him that he was hoping to just have a "friendly chat" with him, Zexion tells him he has more work to attend to, and finishes the conversation by telling Xigbar that if he is through working, then it would be in his best interest to get rest. In addition to this, Saïx had him eliminated so that he could rise in the ranks of Organization XIII.

It is speculated that Xemnas may have known about the rebellious thoughts harbored by Marluxia, and as a result placed Zexion in command of the lower regions of Castle Oblivion in order to weed out the traitor. This would seem plausible based on Zexion's apparent rank and level of competence, though nothing official has been stated in regards to it.

Zexion to some appears to be emotionally distant, but this is not completely true. This is observed in his death. Upon Axel's dialogue with the Riku Replica, Zexion's horrified reaction shows that he clearly does not want to die. He has an undying sense of duty to the Organization, which is certainly not untrue as he is the most competent of the basement members and goes to almost any length to ensure the success of his missions. At times, he can also be humorous and jest with other members when the moment shows itself.

A good example of this is in Kingdom Hearts Re:Chain of Memories where it's shown that he and Axel are having a friendly gamble at which Organization member in the castle will be the next to die (something they've been apparently doing ever since Vexen got killed by Axel). Axel proves to win that particular round when he accurately predicts that Marluxia will be the next to die. He is also particularly cheeky towards Vexen, giving dry and smart retorts when Vexen attempts to reprimand him with his superior ranking.
