From their website:
Fantasy Flight Games is excited to announce the upcoming release of Hoss, a single figure expansion for Tannhäuser. Hoss Harbinger is a descendant of Atlas, the true king of the world. In his veins flows the blood of the ancients, and he wields their powers with ease.
Hoss is a frighteningly powerful individual, able to bend time and space to his will. His manipulation of reality gives him superior agility and his clairvoyant nature gives him the edge in combat. He has joined the Reich in his quest to return his people to glory, and he will stop at nothing to achieve his ends.
Hoss comes with a detailed pre-painted miniature, a character sheet, a rulebook with a unique scenario for Hoss, and tokens for all of his equipment.
