Persuader

The Persuader aka Nyeun Chun Ti is a member of the Fatal Five and a mortal enemy of the Legion of Superheroes. His Atomic Axe can cut through anything, even Superman's flesh. Nyuen Chun Ti grew up to believe that the most important thing was to be able to prove his self-worth. As a result, he got into many fights as a child. As an adult, he was genetically modified to be able to work on heavy gravity mining colonies. As a result, his physical attributes were increased. This only elevated his ideology.
