Even

Unreleased

Even was one of the six apprentices to Ansem the Wise, and the complete being of Vexen. He has been confirmed to appear in Kingdom Hearts Birth by Sleep through the TGS 2009 Birth by Sleep video, in which he is seen talking to Ven, wondering aloud if the two will have a connection in the future.

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.

Eventually, 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.
