In reference to the 'is Reiko Kahn?' debate I have a take that may be fresh and new. No, Reiko is not Kahn. Reiko is a clone of Kahn created by Kahn.
Let's face it, here are the facts. Reiko has a lot of similarities to Kahn.
Reiko first appears in Mortal Kombat 4. We are told he was a general of Shinnok's armies. But as seen later, the Forces of Darkness often team up and back stab each other. So there is nothing stating that Reiko was not created a long time ago, served for Shinnok in the war against the Elder Gods, and narrowly escaped death. After all, Kahn and Shinnok both fight against the Elder Gods. Separately throughout the entire story and 'together' at the Battle of Armageddon.
Shinnok made a clone of himself to fight in his stead during the Battle of Armageddon. Is it so strange to think that Kahn made a clone of himself to fight in his stead at the original battle between Shinnok and the Elder Gods?
We don't see Reiko again until his cameo in Mortal Kombat Deception.
Somebody that looks a lot like Kahn died at the beginning of the Deadly Alliance. This is confirmed to be a clone of Kahn that Kahn made. (Kahn's bio from MKD.) A clone that looks like Kahn, lead Kahn's armies in his absence, and liked to wear his uniform and skull helmet. It was later said that Reiko was Kahn's general. Who better to pose as Kahn than someone that looks like him and has the skills to continue to lead his war?
Reiko was killed by Shang Tsung and Quan Chi; while Kahn went into hiding; Kahn then appears later in Deception's storyline.
How can Reiko be alive for Armageddon? Simple, Havik's ending in Deception is cannon. Only that he had only thought that he was riving Kahn. We know that Onoga was defeated and left for dead in his throne room according to his bio posted by Midway for Armageddon. (It says Onaga's soul was expelled not his body. The host body would have been left for Havik to find.) Havik simply came along after the battle and revived Reiko. Reiko likely just played along; resuming his status as general after realizing Kahn had again gained power in Outworld.
