Göetz von Berlichingen, also known as Machina, Nigredo: the Black Knight, or Michael Wittmann, holds Seat VII on the Obsidian Round Table as a high-ranking member of the Longinus Dreizehn Orden. He is one of the Three Knights, an Einherjar directly serving Reinhard Heydrich and integral to the Order's objectives. His origin lies in World War II, where he served as a Nazi soldier and was the best friend of Lotus Reichhart. Michael killed Lotus during a battle to determine the final member of the Obsidian Round Table. Following this victory, the alchemist Mercurius split Lotus's soul: one half combined with Mercurius's blood to create Zarathustra Ubermensch, while the other fused into Michael, transforming him into Machina and granting supernatural capabilities tied to his new existence. Across Dies irae's narratives, Machina manifests as Nigredo at different points during the Transmutation of Gold in Shambala depending on the route. In the Rea Route, he achieves godhood through Reinhard, enabling his fists to shatter Mercurius's attacks and potentially deliver fatal blows. During Interview with Kaziklu Bey, he confronts Methuselah but is immobilized and expelled from the battlefield using multi-layered spheres of darkness, identified as a significant threat. His primary abilities stem from Die Ewigkeit. His Yetzirah-level power, Deus Ex Machina, designates his fists as a Holy Relic capable of "ending" anything they contact, bypassing defenses and reverting targets to their base state. His Briah-level power, Midgardr Völsunga Saga, erases targets from existence entirely. This erasure requires the target to possess a history—even a nanosecond—to take effect; targets without history remain unaffected. His combat parameters shift: Yetzirah prioritizes magic (MAG: 7), while Briah emphasizes attack (ATK: 7) and synchronization (EQP: 6). Within the Shinza Bansho continuity, specifically Kajiri Kamui Kagura, Machina does not appear directly. His reincarnation, Tenma Ootake, is a member of the Yatsukahagi. The character's names reference historical figures: Götz von Berlichingen, a 16th-century German knight known for his iron prosthetic hand, and Michael Wittmann, a famed WWII Waffen-SS tank commander nicknamed "Black Baron," informing his thematic association with martial prowess and mechanized combat.
