Vexen (ヴィクセン,
Vikusen?), is a scientist who appears in
Kingdom Hearts: Chain of Memories. He is also known as the "Chilly Academic" (いてつく学究,
Itetsuku Gakkyū?). Vexen's original self was Even (エヴェン,
Even?), and he was interested in studying Xehanort's memories. Vexen can control
ice and carries a large
shield in battle that blocks any frontal attacks made against him.
[4] Vexen is voiced by Tatsuya Kando in
Kingdom Hearts: Chain of Memories[12] and
Nachi Nozawa in
Kingdom Hearts Re:Chain of Memories.
In
Chain of Memories, Vexen sides with Zexion and Lexaeus,
other members occupying the castle's basements, to prevent Marluxia's
plan to overthrow the Organization.
[13] He first battles Riku in order to gather data to create a replica of him.
[14][15] However, Vexen cares nothing for his "experiment" and allows
Naminé to manipulate the
Riku Replica's memories against his wishes.
[16]When the Replica fails to defeat Sora, Marluxia threatens to reveal the
shortcoming to Xemnas, forcing Vexen to kill Sora. Encountering Sora,
Vexen says that he came to collect his "debt" and provokes Sora's anger
by making him believe that he controlled Riku rather than created a
replica.
[17]After their battle, Vexen gives Sora the card to Twilight Town with the intention of revealing Roxas's existence.
[18] Marluxia considers him a traitor as a result and sends Axel to kill him.
[19]In Twilight Town, Vexen attempts to reveal to Sora why he feels as
though he has been to Twilight Town despite being fairly certain that
he had never been there.
[20]Sora and Vexen battle again after Vexen tells Sora to throw away his
memories and listen to his heart. As Vexen is about to reveal
Marluxia's plot, he is killed by Axel.
