During the "Hypertension" story arc of the Superboy series, a Superboy from another Hypertime reality was grown to full age to become Superman, but later became Black Zero in the midst of anti-clone sentiment.
In 2011 the Chelsea Art Museum recreated a performance of Black Zero, a happening staged by Aldo Tambellini at Group Center on several occasions between 1963 and 1965.
