Powers and Abilities
Powers
Radiation Production: Joker was transformed into a living nuclear hazard. He gave off dangerous amounts of radiation even passively that made it lethal to be near him, let alone touch without some form of protection. He had no control over this.
Energy Projection: Joker could manipulate this radiation for various effects . At first, he could only project this radiation from his hands as energy beams or fireballs. As his powers grew increasingly unstable, he was able to emit wide range waves of radiation.
Thermokinesis: His powers also caused him to be extremely hot in the literal sense. Powers was incapable of feeling the cold, and his touch could sear even metal.
Mental Illness: As his powers grew, Joker' condition slowly ate away at his mind. This caused him to suffer heightened aggression or lower rationality, making him quick to anger and eventually leading to murderous fits of rage under the slightest provocation and laughing uncontrollably.
