Born of 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.
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.
