Editing Vexen

'''Vexen''', the {{nihongo|''Chilly Academic''|いてつく学究|Itetsuku Gakkyū}}, is the [[Nobody]] of [[Even]] and the Rank IV member of the original [[Organization XIII]]. He controls ice and uses it to command storms and blizzards, freezing his opponents solid, while defending himself with his massive shield.

During the course of experiments into the nature of the hearts and its darkness, [[Terra-Xehanort]] resolved to cast off his body and become a Heartless himself, choosing to bring the other former apprentices of [[Ansem the Wise]] with him, including [[Even]]. Having regained his Keyblade, he steals their hearts.{{storylink|Kingdom Hearts 3D: Dream Drop Distance}} This splits them into Heartless and Nobodies, and those Nobodies became the founding members of [[Organization XIII]].{{storylink|Secret Ansem's Report 7}} Even as a Nobody, Vexen only cared for his research, and was assigned to duplicate the Keyblade wielder's memories and powers via the [[Replica Program]]. Through this program, he created a Replica of [[Roxas]] he named [[Xion]], as well as an inferior [[Riku Replica|Replica of Riku]].<ref>'''''[[Kingdom Hearts 358/2 Days]]''''', '''Xemnas''': "The goal was to duplicate the Keyblade wielder's memories, and through them, his powers—thus making them our own. Vexen oversaw the project at Castle Oblivion. However, our efforts were severely derailed by his unexpected demise. And this particular Replica—the one we called Xion—came to form an identity of her own."</ref>

[[File:Vexen and His Replica 01 KHRECOM.png|thumb|right|Vexen asks the replica how it was to encounter the real Riku.]]

When Marluxia and Larxene begin manipulating [[Sora]] through [[Naminé]]'s ability, Vexen, Lexaeus, and Zexion decide to try use [[Riku]], who has appeared in the castle's basements, to counter Marluxia's plot. Vexen engages Riku in battle, hinting towards the nature of Nobodies and the existence of [[Xemnas]] and taunting Riku about his nature as a being between darkness and light. Sensing a formidable darkness growing within Riku, Vexen decides that he has gathered enough data and returns to program it into his second Replica. Once completed, the [[Riku Replica]] is sent to challenge the real Riku to test its powers. Despite freely using the darkness, the replica loses to the original Riku due to being recently finished and thus having less control over its abilities.

Even with the failure, Vexen decides that an obedient Riku is better than trying to gain control of the original. He decides to take him to the upper levels to help deal with Sora. He offers the replica's services in testing Sora to Axel and Larxene. However, they insist on changing his memories; Vexen rejects that idea, as he believes the replica would be strong enough to wipe out Sora even with different memories. They have [[Naminé]] manipulate the replica into thinking he is the real Riku and that he made a promise to Naminé, something that Sora also remembers doing. The Riku Replica confronts Sora multiple times, but he is defeated each time.

After the replica loses twice to Sora and fails to confront him a third time, Vexen is taunted about his replica by Axel and Larxene. However, they are interrupted by Marluxia, who deems Vexen's experiment a failure. Vexen is insulted, but when Marluxia makes the threat of reporting Vexen's failure to "[[Xemnas|the Superior]]", Vexen reluctantly agrees to face Sora himself. He meets Sora at the entrance to the 11th floor and states that Sora is in debt to him for reuniting him with Riku. Sora is angered, and the two battle. Having been pulling his punches, Vexen instead gives Sora a world card of [[Twilight Town]], claiming to have delved into Sora's heart and found the memories locked in the other side of it. Vexen tells Sora that if he wants to truly defeat him, then he must enter that world, before fleeing.

Meanwhile, Marluxia, Larxene, and Axel note that Vexen is jeopardizing their plans to overthrow the Organization; the scientist intends to reveal the existence of Roxas as well as Marluxia's plan to rewrite Sora's memories to turn him into his puppet. As a result, Axel is sent by Marluxia and Larxene to assassinate Vexen, not only to prevent Vexen from revealing their plan, but also to gain their trust.

Vexen is again defeated, surprised that Sora has such strength even with his memory confused. Upon being told to restore Riku to what he was before, Vexen tells Sora that the replica is fated to sink into the darkness, and that Sora will share that fate if he continues to seek out Naminé. However, right before Vexen can give proper warning about Marluxia messing with Sora's memories, Vexen is knocked down by Axel's chakram. Axel explains that he came to keep Vexen from talking to much by eliminating him, claiming that he can now be nothing instead of a Nobody. Despite Vexen's pleas for mercy, Axel snaps his fingers and incinerates Vexen.

On Day 194, Axel finds Vexen's notes on Naminé, ''[[The Truth About Naminé]]'', hidden within the library at the [[Castle That Never Was]].

After Vexen's destruction, Even's body and soul were swallowed by darkness to await his heart.<ref>'''''[[Director's Secret Report XIII]]''''', p. 29; '''Tetsuya Nomura''': "When a Nobody is defeated, it's a little complicated. If the heart has been released they will return to their original form as mentioned above, but if the heart is still dispossessed by a Heartless, the Nobody will be swallowed by darkness. If their heart, wherever it is in the realm, could be taken back perhaps they could return to their original human form."

To Even's surprise, [[Saïx]] gives him the chance to return to being a Nobody to complete his research on the [[Replica Program]]. Seeing it as his chance to atone for all the harm he caused others in the past, Even accepts and becomes Vexen again, becoming a reserve member of the [[real Organization XIII]]. At the [[Keyblade Graveyard]], Saïx questions the scientist's decision to abandon his humanity a second time; he adds that [[Axel]] gave him a second lease on life. Vexen lies that his research in completing the perfect vessel is all that matters to him. However, he does add that with some more time, they "will replace, not just replicate", becoming true people once hearts are given to them.  <!--not sure how to storylink, Ultimania makes it clear Vexen made the new Dark Riku prior to KH3D ending--> Due to the fact [[Xehanort]]'s younger incarnation, [[Ansem, Seeker of Darkness|Heartless]] and [[Xemnas|Nobody]] cannot coexistence at the same time with the present day version, Vexen had to make replicas to house their hearts in the present day, while also providing replicas for the hearts of [[Vanitas]] and [[Dark Riku|Riku Replica]]. Along with [[Demyx]], Vexen was designated a back-up member by Xehanort, leaving the group without thirteen members.

After Xehanort's failure to turn [[Sora]] into the thirteenth vessel, Vexen created a new replica, which Young Xehanort gave the past heart of [[Xion]]. While forced to create copies of the current main members of the Organization (minus Master Xehanort) to replenish their ranks in case of an emergency, Vexen also began working to create additional blank replicas for housing the hearts of those who truly needed them.

[[File:Atonement 03 KHIII.png|thumb|right|200px|After having rescued Ansem the Wise, Vexen reveals that he wishes to make amends for all he's done.]]

In ''Kingdom Hearts III'', Vexen appears the same as he did in ''Chain of Memories'', devious and obsessed with his Replica research. He even declared that he did not require his humanity to complete his research nor does he care about how others may use his research, only that he sees it to fruition. In reality, this is a ruse Vexen made towards the Organization, as he actually regrets his previous actions and truly seeks to atone. Vexen came to the realization that as a scientist, mistakes are made toward the path of knowledge and wishes to ensure his research does some good, so that he may achieve a measure of forgiveness. To achieve this, he works behind the backs of the real Organization XIII to aid those fighting against Master Xehanort, such as aiding his former teacher Ansem, the Wise and providing replicas for those who truly needed them, such as Roxas and Naminé.

Vexen is one of the most prolific Organization members in battles, appearing as an opponent three times during ''Chain of Memories''. He fights with a large blue shield, which he uses to fend off frontal attacks, making it necessary to attack him from behind. He is also able to use the shield offensively, akin to [[Goofy]], but further enhances the style with the spikes lining the edge of his shield. He can use his cryokinetic abilities to blast his enemy with ice from his hand, and can call forth large chunks of ice from the ground to freeze his opponent solid. He also has the power to create slippery ice patches on the ground, or summon icicles that rise from the ground and follow their target for several seconds. Finally, he can create an unavoidable blizzard that can be resisted only with a [[card break]]. In the remake, Vexen can conjure up a sword out of ice and whack his opponent several times with it before performing a final shockwave which destroys the sword and ends the sleight. Like several other members of Organization XIII in ''Kingdom Hearts Chain of Memories'', Vexen moves by levitating, sometimes several feet into the air.

Vexen also has the ability to collect and manipulate Data. This ability allows Vexen to create Replicas, such as the Riku Replica, and his numerous Vexen Replicas. Not much else is known about this ability.  It can be assumed that he uses his shield, Frozen Pride, to absorb attacks, and collect data simultaneously.   

In ''Kingdom Hearts 358/2 Days'', Vexen has a Limit Break called {{c|Diamond Dust|Limit Break}}, which causes ice glaciers to protrude from the ground.

Vexen, like Goofy, carries a shield into battle. His shield [[Frozen Pride]] is pointed, and is colored blue and silver. He can use it to block attacks, but it is also used to slash foes. If turned upside down, the shield has the vague shape of the Nobody symbol. In ''Kingdom Hearts Re:Chain of Memories'' it can be changed during the sleight "Slide Break," where he freezes ice onto the shield to form a gigantic ice sword that he wildly slashes with before smashing the blade onto the foe. However, his Absent Silhouette does not use it to attack, instead relying on his data replicas and ice magic for his offense, and uses his shield to block any attacks during battle. However, the Silhouette's shield has its own small health bar, and breaks after a while, and leaves him vulnerable until another shield is summoned. In ''Kingdom Hearts II Final Mix'', Goofy can obtain a similar shield through synthesis.
