Rufus Shinra
Bio:
Rufus Shinra is the only offspring of the current head of Shinra and heir to his dynasty. Little is known about this ambitious man, but he is an opprotunist at heart. Minutes after his Father's death he arrives at the Shinra HQ to take up his position as president.
In the past of the game Rufus was directly responsible for funding the terroist group known as Avalanche and fed them critical information about operations with which they were able to formulate offensive attacks against Shinra. Later on it is discovered that Rufus has been betraying the company and he is captured by the Turks to be used in a prisoner exchange for their leader's daughter, who ran Avalanche.
After the events taken by Sephiroth all of this becomes a moot point as nearly everyone at Shinra HQ is killed by Sephiroth or Cloud.
