Li Mei won Shang n' Chi's fake tournament.



Ka-Tra

I'm not exactly sure who one but i'm like 99.9% sure that Scorpion, Frost, and Jax had true endings.

SPOILER:







in the into movie for MK D it said that the Deadly Alliance won... but raiden was the last one to fight them and was defeated.

Correct. With Shinnok's amulet at their disposal, the Deadly Alliance proved to be too much for Earth's heroes. Even Raiden was no match for the combined might of Quan Chi and Shang Tsung. However, once the Dragon King's army was ressurrected, the Alliance shattered, and Quan Chi and Shang Tsung resorted to infighting to determine who would command it. When Onaga himself showed up, the duo knew they needed help fighting him off, and so enlisted Raiden's assistance in battling the ancient warlord. However, even the three of them, backed up by the power of Shinnok's amulet, could defend against Onaga and, in a desperate play, Raiden resorted to self-destructing, hoping the blast of holy power would annihilate the Dragon King. Alas, it did not, and Shang was caught in the blast, killing him. As for Quan Chi, there is no knowing what had become of him, though it is speculated that he, too, did not survive the blast.
