Mythology
Hailing from Germany, Faust I is the main character of the renowned German tale, "The Tragedy of Doctor Faustus". Johann Faust VIII is the eighth-generation descendant of the legendary Doctor Faustus.

As a man who was so consumed by lust for all the pleasures of the world, Faustus made a deal with the devil to gain them. For necromancy skills, the Devil (more commonly known as Mephistopheles in Faust literature) also granted Faustus youth and riches. In the end, Faustus died a terrible death when Mephistopheles came to claim his soul at the end of the seven year contract.

In Shaman King
Johann Faust I is the ancestor of Johann Faust VIII. He was a necromancer who lived in the 1500s in Germany. He had made a deal with the demon Mephistopheles and thus gained immeasurable power. He took part in the Shaman Fight but before he became Shaman King he was killed by the demon.

His knowledge however was sealed away in a dark chamber where it was later discovered by Johann Faust VIII.
