Before The Fall of humanity at the hands of The TITANS, the MAPPO Corporation, headed by the misanthropic and megalomaniacal Japanese scientist, Dr Kazushi Nikken, breeds human/animal hybrids in a secure, top secret facility somewhere in North Africa. The Hybrids are composed of numerous African animal species including Warthogs, Elephants, Camels, Zebras, Rhinos, Hippos, Giraffes, Hyenas, Gorillas, Lions and Crocodiles. The process involves implanting embryos into the wombs of kidnapped local women who are disposed of after giving birth. Each child is branded after birth marking them as the property of MAPPO.
These Elephantmen are trained from birth to be soldiers and killers and are indoctrinated with an Orwellian mindset to think of themselves as property of the MAPPO Corporation and to deny any concept of free thought.
Upon discovering these experiments, the United Nations send in an army to storm MAPPO’s Secret base. While their mission has not been elaborated at this stage it seems to be a combination of liberating the Elephantmen, investigating the attacks on the local populace and ending the development of MAPPO’s illegal army.
MAPPO turns the Elephantmen on the U.N. troops, and horrendous casualties are inflicted on both sides. Ultimately, the U.N. succeed in subduing the Elephantmen and the MAPPO Personnel are arrested. The Elephantmen are rehabilitated and released to establish their own lives in VERY limited programs in the outside world where they are generally welcomed with distrust and horror from humans. Many of the Elephantmen were assigned jobs by the government.
Living with the humans had proven to be incredibly difficult for the Elephantmen. The war in which they fought had great consequences as people from both sides (Elephantmen included) lost many loved ones. Not all of those who survived retained their sanity, in fact some became active hunters who tracked down Elephantmen, and then executed them. The elephantman soldiers were haunted by memories that were still raw, with some people being driven to insanity due to being unable to let go of the past. It is evident that the Elephantmen themselves show some level of regret towards what they did during the conflict.
