Rain is one of the generals of Shao Kahn. Rain eventually discovers that he is the prince of Edenia, so he joins Kitana and betrays Shao Kahn, siding with the Earthrealm warriors. His powers revolve around the weather and the use of lightning and water.
In terms of gameplay, Rain is somewhat challenging but can be beaten if the player does not provide any chance for the character to counter attack. He will take use of his projectiles and constantly use his lightning to attack the player.
