The Forgotten

As an addition to the Original Oct group, I give you, the Forgotten.

Early Life: Originally created on the planet Spheres Magna by the great beings 100,000 years ago as a failed experiment, the great beings allowed him to thrive on the planet. It is mentioned that he once took place in the construction of the powerful Mata Nui robot for a brief time. After the "Shattering" he, the matoran, and all who inhabit fled inside the giant robot to escape the planet before it's destruction.

Forgotten had always been astonished by the power of the great beings and their ability to create unimaginable things.
This obsession led him to his life's work, to create something no one has ever accomplished.

For years he studied, tested, and finally he came to his conclusion, his life goal to create the "Altraniem".

The Altraniem is an artifact that can give almost any being the power to control every element that exists in the matoran universe.

When the Order of Mata Nui Discovered the Altraniem's existence, they grew concerned. The Order feared that the Altraniem's power might be used as a weapon of mass destruction. The OoMN informed the Forgotten to deliver them the artifact, Forgotten refused the request.

The OoMN decided to forcefully remove the Altraniem from the Forgotten's protection without warning.
When Forgotten discovered this, he was enraged. Having allready created an army of combat drones to attack the Order and by doing this, he successively retrieved the device.

Feeling that a war was coming, the OoMN sent a noble team of toa Haga to battle the Forgotten and return the Alraniem. After countless battles, the toa remained victorious and claimed the Alraniem. The Forgotten was defeated and badly injured, he was to be arrested to the pit, but with great efforts, he escaped, and vanished into hiding in Stelt.

For years he is committed to return his device back to him. He later created his own living assassin and assistant to help aid him in his struggles.
