Doctor Phosphorus

Dr. Phosphorus, was a scientist turned radioactive monster

History
Doctor Phosphorus was originally known as Dr. Alexander Sartorius. While working with a nuclear reactor, the reactor cracked and shot him full of radiation making his skin and organs invisible and making his touch radioactive. He could also shoot radioactive energy beams. Angry at his hideous transformation, he began seeking revenge on those he deemed responsible. He sold his soul to Neron in exchange for control over his previously uncontrollable powers. He became an assassin for hire and tried to kill Starman when hired by Mist, Starman's archenemy. He would face him a second time and give Starman terminal cancer. The third encounter would send Doctor Phosphorus plummeting into the earth. He would eventually be retrieved by Cadmus Laboratories who wanted to study him as an infinate power source. He escapes and seeks revenge on the people he blames for his condition, but is stopped by Batman and imprisoned in Arkham. The Batman Beyond villain Blight was based on Doctor Phosphorus. Also in the TV series The Batman, Firefly would be transformed by radioactive isotopes into the villain "Phosphorus". Both Phosphorus and Blight had similar appearances and the exact same powers, as well as trouble controlling them.
