Which 4 kahns ? Excluding onaga and shao , whos left ? Kitana kahn XD ?? She just got a title cuz of plot armor of a 16 bit . No decsions , no feats , nothing . Her beating shao is as bullshing as anyone losing to barak in story . Remind me if i missed any kahn .
In the reboot timeline, we've seen four Kahns:
- Shao
- Mileena
- Kotal
- Kitana
Onaga would technically have ruled Outworld before Shao, but I'm not counting him since, in this timeline, we haven't actually seen the character.
Shao is obviously the most successful Kahn, though of course he rules by strength and brutality. He did make Outworld, and the subsequent Realms he conquered and absorbed, strong under his rule, though the people were obviously oppressed.
Mileena, we actually don't know much about her rule, aside from that she was Kahn for approximately 17 years, was dubbed the "mad" empress, and was rebelled against and overthrown not because of that, but because she refused to ally with Earthrealm against NetherRealm when NetherRealm was assaulting Earthrealm. We saw more of her as a rebel leader attempting to regain her throne.
Kotal's rule is next, and we know he ruled for roughly a dozen years. In that time, he made or broke alliances with Earthrealm when it suited him, committed genocide on the Tarkata, was played by his right hand (D'Vorah), decided to capitulate to Shinnok post-haste, and needed the Kombat Kids to help keep his throne secure from Mileena's rebellion. Oh, and he had a thing for having statues of himself made. His rule was far from impressive. The people of Outworld, mostly, were lease oppressed than under Shao though, which was a plus.
Lastly, we have Kitana's rule, which was very, very short lived, originally because Kronika reset time, and then because of Shang Tsung's interference, she was usurped by Shao and Sindel. During her very short rule, however, she united all the peoples of Outworld under a common cause for good for the first time in its known history, and before Shang's meddling, aided in preventing Kronika from creating her New Era.
I do agree that Kitana defeating Shao in single combat is certainly a stretch.
