The Mortal Kombat and Mortal Kombat II comics were written by Tobias and are canon.
Yes they are.
In them, Liu Kang has been training for years and specifically receives an invitation to fight in the tournament as a representative for the Shaolin. In MK II prequel comic it's specifically said by Liu that they train to save the world. That is explicitly their purpose as representatives of Earthrealm so Liu fulfilled what he'd been training for. In the MK comic he even gets express permission to go fight and is told that he CAN win but only if he's balanced and focused blahblahblah.
Of course, that doesn't mean he's a "chosen one" destined for greatness, it was a far more general take then "destiny." He was a monk who trained for the tournament to protect Earth. He then had to go and accomplish his task.
As I recall, he was never actually called the "chosen one" until the 3D era, though I'd need to double check that. I certainly don't recall it ever being mentioned in the original trilogy.
The MKII comic also explicitly names Liu Kang as the winner of the tournament. There was no need to speculate or dispute. It was extremely clear about Liu winning. This was all in 1993. This is further elaborated on in MKII itself where Liu Kang's profile outright states he returns after "winning the Shao Lin tournament from Shang Tsung's clutches". That Shaolin tournament is Mortal Kombat (which Shang had seized control over pre-MK, of course).
You've misunderstood me, so allow me to clarify. In each of the original games, you had to wait until the sequel to find out who won each game. You only knew Liu Kang defeated Shang in
Mortal Kombat (1992) due to the attract screen or prequel comic for
Mortal Kombat II, there was no way to know from playing
Mortal Kombat (1992) itself.
Your above paragraph validates what I'm saying.
All this stuff was established by MKII (or even pre-MKII) with Liu Kang as the greatest member of an order specifically trained and designated to combat Outworld.
Outworld didn't exist until the development of
Mortal Kombat II, this concept did not exist originally for Liu Kang. He was being trained for the tournament to defeat Shang.
Liu Kang's profile states he is the "prime target" of Outworld extermination squads and he is responsible for thwarting Shao's previous schemes. EG He's the winner. It also explicitly calls him the "shaolin champion". This is in reference to the MK tournament (which the Outworld tournament is a part of).
It specifically states: "After the Outworld invasion, Liu Kang finds himself the prime target of Kahn's extermination squads. He is the Shaolin Champion and has thwarted Kahn's schemes in the past. Of all the humans, Kang poses the greatest threat to Shao Kahn's rule."
As I mentioned in another post above, it calls him the "Shaolin champion" and not "the chosen one," as that concept didn't exist yet. Being the 3rd game and with the lore further developing, the concept of Liu becoming the prime protagonist is being shown for the first time. This is a narrative development that supports what I've been saying, since this wasn't the case in
Mortal Kombat (1992), and while Liu was important in
Mortal Kombat II, he wasn't bound up by "destiny" yet. Again, the narrative evolved over the years to bring Liu into priminence more.
For him winning the Outworld Tournament, it mentions he's the Shaolin Champion referencing the Shaolin Tournament, not the Outworld Tournament (as they're seperate things). While it could imply, by defeating Kahn's schemes, that he won
Mortal Kombat II, it's not clear and could also only mean the first game. It was unclear enough back in 1995 that it still wasn't certain, and was debated, for years as to who won
Mortal Kombat II.
We know now that he did win it, and I believe that was stated in an interview or something back in the day, which ended any debate.
Also his ending in MKII outright states that Liu defeating Shao was his destiny so take that for what it's worth as 'chosen one' acknowledgment.
It says he "... finally realizes that the events that have taken place were all fulfillemnt of his destiny."
No mention of "Chosen One," again, as that concept did not yet exist. It's all still pretty generic/vague, but the concept was taking shape.
