Shao Kahn
In 2011's "Mortal Kombat" reboot, which serves as a reboot of the first three games, Shao Kahn is once again the main antagonist and final boss of the game's Arcade Ladder and Story Mode. Shao Kahn kills Raiden after acquiring Blaze's powers, but the thunder god is able to send prophetic messages to his past self. As Shao Kahn invades Earthrealm, Raiden chooses not to intervene until the Elder Gods, enraged by the former's violation of the Mortal Kombat tournament's rules, empower Raiden and allow him to kill the emperor.
