Even

Unreleased

Even was one of the six apprentices to Ansem the Wise, and the complete being of Vexen. He is a confirmed character to appear in Kingdom Hearts Birth by Sleep.

Dabbling In Darkness
About a decade prior to Kingdom Hearts, Even was one of six apprentices to the ruler and scientist of Radiant Garden, alongside Xehanort, Braig, Dilan, Aeleus, and Ienzo. Worried the Darkness in people's hearts would eventually consume his world, Ansem began performing tests on Xehanort's heart, which Even showed particular interest in. Eventually, he created a laboratory in his castle's basement for such experimentation. However, Even and the other apprentices had their own intentions for the laboratory, and began conducting inhumane experiments on the human heart and the darkness within it. Such experimentation led to the creation of Heartless. Ansem quickly discovered their secret experiments, and immediately ordered them to stop. One day, after being advised to review their research data by King Mickey, Ansem found that the effects of their experiments had become irreversible.

Eventaully, Even and the other five apprentices dabbled too deep into darkness through their continued experiments. Even, along with the others, was consumed by the darkness, producing a Heartless. However, the apprentices all had strong wills, and so Even also became his Nobody, Vexen. The six Nobodies formed Organization XIII, and banished Ansem the Wise to the Realm of Darkness.

Kingdom Hearts Birth by Sleep
Even is confirmed to appear in the upcoming game Kingdom Hearts Birth By Sleep. Since the game takes place ten years prior to Kingdom Hearts, he will probably be conducting experiments alongside the other five of Ansem the Wise's apprentices.

Kingdom Hearts: Chain of Memories
Even appears as his Nobody Vexen in Kingdom Hearts: Chain of Memories, still a scientist. He creates the Riku Replica, and is later ordered to eliminate Sora while in Castle Oblivion. After their second battle in the castle's Twilight Town-based floor, Axel appears and eliminates Vexen with an incredible amount of fire. Vexen faded into nothingness, therefore ending the existance of Even.

Also during the game, Vexen assists two of the other former apprentices of Ansem the Wise: Lexaeus, who was Aeleus, and Zexion, who was Ienzo. Their goal was to stop Marluxia, one of the later members, from using Sora to overthrow the Organization.
