History

  An explorer from the Anti-Matter Universe who came to the positive universe to investigate Earth. Although the creature was immensely powerful, his intelligence was not comparable to human minds. He could not communicate or empathise with positive matter beings and was unaware that contact with positive matter would be fatal to both him and Earth. The Anti-Matterman was opposed by the combined forces of the JLA and the JSA, who, with the help of Doctor Fate's magic, could battle the creature without causing an anti-matter explosion. Finally, the Spectre (I) managed to send the Anti-Matterman back to his own universe. He has not been seen since.
