Wolfgang Schreiber entered the world on February 27, 1920, as the son of Berlin brothel operators. His parents, disappointed by his male birth and desiring a female successor, castrated him with scissors shortly thereafter and renamed him "Anna." Raised biologically male but presented as female, he became a sought-after child prostitute whose popularity eclipsed his mother's. Her ensuing jealousy fueled relentless abuse, culminating in her gouging out his right eye. Clients continued exploiting him, even utilizing the vacant eye socket, until trauma-induced madness drove him to murder his parents and embrace serial killing alongside prostitution.
His trajectory shifted during a murder attempt against Wilhelm Ehrenburg, whose violent counterattack drew Beatrice Waltrud von Kircheisen and Eleonore von Wittenburg. Reinhard Heydrich intervened, subduing Wolfgang by thrusting fingers into his empty eye socket. This encounter secured Wolfgang's place as the inaugural member of the Longinus Dreizehn Orden, where he pledged loyalty to Heydrich and reclaimed his father's surname.
As an SS Major in World War II, Wolfgang commanded the Eastern Front Assault Corps within the Einsatzgruppen, employing brutal tactics that slaughtered allies and enemies indiscriminately. He faked his death during a 1942 purge to operate covertly for the Obsidian Round Table. Key operations included the June 1944 Normandy massacre of Allied paratroopers—leaving one survivor to expose the Order—and the April 30, 1945, Battle of Berlin. There, obeying Eleonore's directive, he completed a ritualistic swastika by destroying landmarks while sparing Soviet forces to ensure their hollow victory. He later departed the material world alongside Heydrich for Valhalla.
Augmented by the Ewigkeit Formula, Wolfgang possesses immortality, halted aging, and rapid healing. His body houses 185,731 souls that amplify his physical prowess. In combat, he favors evasion and long-range attacks using infinitely-ammo Luger P08 and Mauser C96 pistols, which ricochet off empty space. His Yetzirah relic, Lyngvi Vánagandr, manifests as a WWII-era Zündapp KS 750 motorcycle that disregards inertia and physical laws to achieve extreme speeds.
His signature Briah Niflheimr Fenriswolf embodies his core desire "not to be touched." When activated, he moves faster than any opponent regardless of their speed or temporal manipulation. Physical contact during this state triggers his "True Briah," fusing him with his relic. His hair lengthens and glows white as madness consumes him. Opponents touching him suffer explosive damage while he regenerates instantly, becoming nearly unstoppable despite catastrophic injuries and peaking battle parameters.
Wolfgang exhibits an animalistic, unstable personality marked by violent outbursts and profound touch aversion stemming from childhood trauma. He displays uncharacteristic gentleness toward Rusalka Schwägelin, whom he calls "Anna," sharing a one-sided bond. In the Kei route, Valerian Trifa assassinates him mid-Briah activation during a Tsukinosawa High battle. In the Marie route, he tortures a dying Rusalka for vengeance before confronting Shirou Yusa and Ren Fujii at an amusement park. Ren halts time, enabling Shirou to destroy his relic, leading to Wolfgang's death as he reenacts his past.
Later media like Kajiri Kamui Kagura omit direct appearances but feature reincarnations: Teirei and Niko, embodying his masculine and feminine aspects, serve as Yakou Madara's shikigami. The Omnia vincit Amor timeline depicts him living peacefully and sanely within a loving household.
