Tzykrow (ツァイクロウ Tsaikurou?) is a former Höher Krieger who served as the instructor of the Kammer Gruppe, the Mauser School's secret unit, where he personally trained Alita. He was one of three known surviving Künstlers alongside Alita and Frau X until the revelation of the Einherjar. Tzykrow subsequently joined HIGH ORDER and reported directly to Aga Mbadi. Following his defeat by Alita, Tzykrow became Super Nova's first patient and later servant.
