History

A brilliant scientist and an expert in sound, Dr. Anton Koravyk is a good friend of Niles Caulder, the leader of the Doom Patrol.  While Koravyk is busy conducting an experiment in time warps, something goes awry and he is devolved into a towering Neanderthal named Kor. 
 
Going on a rampage through Johannesburg, and carrying one of Koravyk's sonice weapons, he is stopped when the Doom Patrol manages to reverse the effects of the accident.
