Obadiah was created by MAPPO in North Africa in the year 2224. He was the result of human/animal hybrid testing at the hands of Dr. Nikken. After being used in private wars around the world, the UN stormed Nikken's facility and released any remaining Elephantmen. Obadiah was able to turn himself into a successful businessman and runs Horn Industries. He is also married to Sahara, which is the cause of much debate due to being an interspecies marriage.
Obadiah Horn was created by Richard Starking and artist Jose Landronn.
