Reno Shinra

Shinra was originally a small weapons manufacturer known as the Shinra Manufacturing Works. Upon discovering how to refine Lifestream into Mako energy as an electrical energy source, they exploded in power and set up Mako Reactors all around the Planet. With their ever-increasing finances, they expanded into many areas, including space exploration. As people became dependent on Shinra's energy and commodities, President Shinra, the owner of the company, became a global autocrat.

Starting a private army, using Mako energy to power the elite SOLDIER class and funding an undercover corps called the Turks, Shinra ruled with an iron fist and began performing human experiments to create supersoldiers. When the people of Wutai disagreed with setting up Mako Reactors to their land, Shinra sent in their army to force their influence, starting the Wutai War........
