Aeleus

Unreleased

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

Dabbling In Darkness
About a decade prior to Kingdom Hearts, Aeleus was one of six apprentices to the ruler and scientist of Radiant Garden, alongside Xehanort, Braig, Dilan, Even, and Ienzo. Worried the Darkness in people's hearts would eventually consume his world, Ansem began performing tests on Xehanort's heart. Eventually, he created a laboratory in his castle's basement for such experimentation. However, Aeleus 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, Aeleus and the other five apprentices dabbled too deep into darkness through their continued experiments. Aeleus, along with the others, was consumed by the darkness, producing a Heartless. However, the apprentices all had strong wills, and so Aeleus also became his Nobody, Lexaeus. The six Nobodies formed Organization XIII, and banished Ansem the Wise to the Realm of Darkness.

Kingdom Hearts Birth by Sleep
Aeleus 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
Aeleus appears as his Nobody Lexaeus in Kingdom Hearts: Chain of Memories. He works with two of Ansem the Wise's other former apprentices: Vexen, who was Even, and Zexion, who was Ienzo. Their goal is to stop Marluxia, a much later member of the Organization, from using Sora to overthrow the Organization. To do so, Lexaeus appears to Riku while he is in Castle Oblivion, attempting to make him give in to his darkness. Riku refuses, and Lexaeus attacks him, planning to eliminate him if he cannot be manipulated. In the end, Lexaeus uses the last of his strength to swallow Riku in darkness, resulting in his own destruction. However, in Kingdom Hearts Re:Chain of Memories, Xehanort's Heartless takes over Riku, and vanquishes Lexaeus. Either way, Lexaeus fades into nothingness, ending the existance of Aeleus.
