Mortal Kombat 1
Rain is an Edenian who bears witness to Shao Kahn's invasion of his homeland as a youth. Many centuries later, he betrays his homeland during the invasion of Earthrealm and joins Kahn's forces. During the events of Mortal Kombat: Armageddon, Quan Chi informs Rain that he is a direct descendant of Argus, the protector god of Edenia, making him a half-god. Rain wishes to kill both Taven and Daegon in order to be able to win the ultimate prize and power promised from defeating Blaze, but in Konquest mode he is defeated by Taven in Arctika before escaping through a watery portal.
Ed Boon named Rain after the Prince song "Purple Rain". He was portrayed by John Turk in both instances. In the 1997 film Mortal Kombat: Annihilation, Tyrone Wiggins plays Rain. Rain also appeared in one episode each of MK: Defenders of the Realm, voiced by Rino Romano, and Mortal Kombat: Conquest, played by Percy "Spitfire" Brown.

Mortal Kombat 3 
Born in Kitana's former world of Edenia, Rain was smuggled away from the realm as a small child shortly after Shao Kahn's take over. Thousands of years later he resurfaced, his allegiance belonging to Kahn. He chose to betray his homeland rather than suffer at the hands of Kahn's extermination squads.
Mortal Kombat: Armageddon
The Edenian race is descended from the gods. That is the reason for our longevity, our nobility, and our strength. But I am more than a distant relation to the deities of old. I am a direct descendant of Argus himself. Only recently have I discovered my royal heritage. Quan Chi, an emissary of Shinnok, revealed to me that I am entitled to great power ? and control of Edenia. My father hid my identity for fear it would complicate his plans for succession. He favored his sons Daegon and Taven and groomed them to one day replace him as Protector of Edenia. But he foolishly tied this plan to a quest to save the realms from Armageddon, leaving open an opportunity for me to seize the power that is rightfully mine. Though it seems the Forces of Light seek to steal the prize from me, Quan Chi has made plans to assure my victory. He and his allies will help fend off the Forces of Light as I make my way to Blaze. But before this final battle, I must ensure that Taven and Daegon cannot challenge my ascension. I will finish them both before they complete their quest.

A refugee orphaned by Shao Kahn's conquest, Rain grew up under the protection of the Edenian Resistance. An exceptional fighter, he soon rose through their ranks. As his reputation grew, so did his arrogance. When Rain demanded leadership of the Resistance forces, he was refused. Infuriated, he turned against his rebel comrades and betrayed them to their sworn enemy.

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 Earthrealm 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.

Mortal Kombat: Armageddon
The half-brother of Taven and Daegon, Rain absorbed the power of Blaze and became a full god. I had not anticipated that the victor would be the son whose true identity I have hidden for so long. I bestowed the title of Protector of Edenia on Rain, but my pride in my son was misplaced. He uses his power to enslave Edenia. And now that I have ascended to Elder God status, I am forbidden to stop him.
Mortal Kombat (2011)
Shao Kahn had used Rain to crush the Edenian Resistance. But had not granted him an army. For this betrayal, Rain drowned the emperor in his own blood. A grateful Raiden thanked Rain for eliminating the emperor and saving Earthrealm. His heroics were befitting of a son of Argus. Rain's lost heritage was a revelation to him. That he was a direct descendant of an Edenian god, proved his superiority. Power was his by right. His divinity confirmed, Rain's path was clear. He would use Shao Kahn's army to rule not just Outworld, but all the realms. To Raiden's surprise and horror, Rain's first target is Earthrealm.
