Mortal Kombat 3

Fed up with continuous losses in tournament battle, Shao Kahn, who had lost to Liu Kang in the Outworld tournament, enacts a 10,000 year-old plan. He would have his Shadow Priests, led by Shang Tsung, revive his former Queen Sindel, who unexpectedly died at a young age. However, she wouldn't be revived in the Outworld. She would be resurrected in the Earthrealm. This would allow Shao Kahn to cross the boundary lines and reclaim his queen. When Sindel is reincarnated in Earthrealm, Shao Kahn reaches across the dimensions to reclaim her. As a consequence of his action, the Earthrealm becomes a part of the Outworld, instantly stripping billions of their souls.
