Rain fights valiantly for the emperor Shao Kahn. But it would be Kahn's own step daughter, the princess Kitana who turns Rain against him. Like Kitana, Rain's origins also come from their former realm of Edenia. He learns that his father was once a general in Edenia's army and died at the hands of Shao Kahn himself. Enraged at the truth about his history, he joins Kitana in aligning with the Earth realm warriors. But his allegiance comes under question when he mysteriously disappears during an extermination squad attack. To prove his loyalty he embarked on a suicide mission to destroy Shao Kahn and end the menace once and for all.
