Mortal Kombat 2 is the most confusing one. Most of the fights in MK2 that people believe are canon are just assumed by various clues such as Kung Lao vs Baraka. People still debate whether it was Raiden or Liu Kang and Kung Lao who killed Kintaro.
Raiden doesn't have much power in Out-World where I'm assuming MK2 took place. I think I know who fought what...
Spoilers ahead...
MK1:
Scorpion VS. Sub-Zero:
After his death Scorpion wanted revenge on the person who killed his family and himself. Sub-Zero was under the control of Shang Tsung as stated by many sites, fics, etc.
So they fought: Conclusion?: Scorpion won. How? During MK2/3/4 we find out Scorpion killed the original Sub-Zero and he later became Noob.***
Kano VS. Sonya:
Sonya was after the killer of her partner, and a person who she was chasing after.
Kano just wanted her dead.
So they fought: Conclusion?: Sonya won stated in MK

A but he was thought dead but he reserfaced after MK2
Liu VS. Shang:
Liu wanted revenge for Kung Lao his ancestor, and to protect Earth Realm from Shang, and the other guys.
Shang has to win MK for the last time
Who won: Liu Conclusion: It is though Shang somehow survived *remember MK3/etc.?* But yes Liu one and became the MK tournament winner..
What doesn't make sense:
Reptile: Nothing is stated of him fighting
Goro: We think either Johnny Cage won, or Liu did not sure... yet he survived till MK

's story-line so far...
Johnny Cage: Not sure since no records of it...
Raiden: May have fought Shang? But he could have been weakened...
*****************
MK2
Who fought?
Liu VS. Shao Kahn
Liu is defender of Earth Realm, thus he had to destroy the threat Kahn...
Kahn wanted to rule Earth Realm but first he had to defeat its champion..
Who won? Liu which led to the events in MK3 since it states Liu stopped Kahn many times before he killed him. *Which he didn't due too MK

A and MK

GC
Noob Saibot VS. Scorpion:
After dieing at the hands of the Hell-Spectre Sub-Zero was reborn himself a Hell-Spectre. Thus he wanted revenge on Scorpion or so we think. Plus Quanchi with MK4 story line behind it would want Scorpion dead.
Who won? Neither Conclusion: The events of MK3, and MK4, and MK

A, and MK
Kung Lao VS. Shao Kahn
Every generation the Locust society brings a new Kung Lao to fight for Earth Realm and give him the trade mark hat.
Kahn wanted all of Earth's warriors dead.
Who won? Neither Kung Lao escaped with his life leading into the events of MK3, but dies before MK4
Baraka/Tarkaten people VS. Heros:
Baraka was the only one to survive in MK2 for what we know. The others killed Tarkaten and survived.
Kintoro VS. Johnny Cage
Johnny is again displayed to have killed this monster. If it is cannon is not for sure. All we know is the forces Kahn sent to kill him succeeded in MK2
Johnny Cage Vs. Reptile
Don't ask. Its in his story line.
Reptile was sent by Shao Kahn to assiassinate all of Earth's heros.
To help regain his people he preformed this act. *which is proven Kahn was lieing all along to Reptile during MK3*
Who won?: Best guess is Reptile due to his MK:3 story line. Plus Reptile had to fir somewhere here...
What doesn't make sense:
Raiden: Nothing is stated of him helping again...
Shang: He was supposively dead. Could have been making Mileena in MK2
Mileena: Didn't make here real appearance till MK3/4 was the clone created by Shang
Sub-Zero: was Noob
Smoke: Was already a robot by than.
Jade: Now this I think she kept Mileena from attacking Kitana
Kitana: Was evil at the time. She was the adopted daughter of Shao Kahn she didn't meet Liu in MK2 is for sure.
Ermac: Was supposively fighting Ashrah, and other threats like Johnny Cage at this time.
Horn Buckle: Who? *J/K* We don't know.
Jax: Was getting his arms at the time. Also was searching for Sonya
MK:3/UMK3/MK:T The biggest time line ever in fights...

After his defeat in MK1 he wants Liu D-E-A-D.
Liu wouldn't mind kicking Shang's ass again.
Winner: Undecided... Due to MK

A story.
Kung Lao VS. Kahn
Think of Liu's story line good.

Sub-Zero Vs. Scorpion:
The new one is attacked by the Hell Specter after being mistaken for his older brother.

Noob Saibot VS. Shao Kahn
After being caught by Shao Kahn he is almost killed again. He is spying for Shinnok.
