Rain

Rain is a half-god. He is the child of the Edenian god Argus. Because Argus was ashamed of his half-blood child he send him away. But because of his status Rain still got a high-ranked position in the Edenian army.

When Shao Khan invaded Edeni, Rain mysteriously disappeared. When Shao Khan started invading Earthrealm, Rain mysteriously reappeared and fought for the Emperor. When he was confronted by Kitana, she told him that Shao Khan was the one who killed his adoptive father. Hearing this Rain vowed to kill Shao Khan.

Rain never managed to confront his father's killer because Shao Khan was defeated by Liu Kang.

Later Rain found out that he was the son of Argus. After that he started to refer to himself as Prince of Edenia. He decided to try to kill his brothers Taven and Daegon to claim the ultimate prize for himself.

He fought on the side of evil until Armageddon came and he was killed alonside every other warrior.

After Raiden changed the timeline Rain fate somewhat changed. Instead of becoming a Edenian general he was adopted by rebels, who trained him in martial arts. Although Rain became a great warrior his greed for power caused him to betray his fellow rebels after being denied leadership. Now Rain fights on the side of Shao Khan's armies.
