NegaTaint is the corrupting influence of the lesser ABS found in the NegaVerse. Nega-ABS has transmutative properties and is capable not only of incorporating the molecular structures of other universal Leg-Ores into itself but also of forcing its own strange makeup into them. This process of contagion is usually progressive and highly aggressive, transforming affected ABS at an advanced speed. Unless the affected parts are cut out, removed from contact with the source material, and utterly obliterated, NegaTaint can have a one hundred percent conversion rate. NegaTaint is naturally generated by anything native to the NegaVerse but only exists in significant amounts in truly potent Creations or Characters, such as a NegaPortal or Nega-BlokTrix herself.
