MK1 Rain Theory/Idea
I have a theory/idea that Rain was a god but was cast down by his parents and became a mortal. Because I hoped for demigod Rain to be explored in this timeline, I don’t like the idea of Rain being a sorcerer. It’s not the worst decision since Rain can still be a well-written character, though I was still disappointed.
This idea came to me randomly so it’ll most likely be disjointed which I apologize for. I was inspired by Greek mythology. There is a story of Zeus stripping his children, specifically Apollo, of their powers and making them mortals so they learn a lesson.
Here is my theory/idea:
Born the youngest son of the gods Argus and Delia, Rain was a powerful god of water. He had a happy life with his parents and brothers- Taven and Daegon, but grew to be arrogant and believing mortals were lesser than him. This attitude led to his downfall. Alongside his brothers, Rain threatened to harm a country due to them not worshiping his family to his satisfaction. Disgusted by their children’s behavior, Argus and Delia stopped their children and planned to punish their children accordingly. With the help of Liu Kang, Argus and Delia decided to strip their sons’ godhood and have them reborn in the mortal realm- Outworld- so they learn to appreciate and care for mortals. Rain- regressed to a baby- would be raised as Zeffeero by a woman called Amara. He would grow to be kinder and ambitious, leading him to learn sorcery and become the kingdom’s high mage; I headcanon that Rain used his water magic to heal people as well. He’d live his life on the right path until Shang Tsung manipulated him and unleashed his darker impulses. His actions in the game would still be the same, including his sort of redemption in his tower ending.
In a future game, the Taven/Daegon plot could return though, instead of their quest is to prevent Armageddon, Rain, Taven, and Daegon would race to their family’s original temple (through memories and clues left by their parents) for the chance to regain their godhood as long as they are deemed worthy. Other characters can be involved by the villains learning this and trying to achieve godhood while the heroes try to stop them. This gives NRS the opportunity to bring back Taven, Daegon, Argus, Delia, and Blaze into the New Era. Rain’s story could end either with him being a god again but with a better understanding and care for mortals or he decides to stay mortal.
I don’t think this will happen in the game since I think the canon reason why Rain is not a god/demigod is because Liu Kang didn’t want to risk him becoming the arrogant, power-hungry person he was in previous timelines. Also, the Armageddon tower was already referenced in MK1 so it'll most likely not come back.
