The Noob-Smoke ending was pretty cool, tho I wish there was more of a revelation about Smoke. In both their bio and ending Noob's half DOMINATED Smoke's half.
Out of the others I liked Kira's how she killed Kobra cuz I'm hoping to not see Kobra around for another game. Sindel's has probably been my favorite so far.
Dairou's SUCKED COMPLETE MAJOR ASS! The whole character idea, the moveset, the bio, the ending, the look, EVERYTHING about Dairou sucked. I thought for sure this would be round 2 of me bashing Bo' Rai Cho about being the worst character in the game but I would rather see the burping and farting of Bo' Rai Cho than Dairou anyday.
Jade's was a let down, she's my favorite character and her ending just doesn't seem well thought out and makes it sound as if they don't plan on using her again.
Out of the newcomers judging by their character and ending Ashrah, Havik, Darrius, and Kira seem like they may return.

Oh yeah, I also couldn't help but be disappointed in Li Mei's. That hot piece is banging the Dragon Kind now. Seriously though with all the buildup for her struggle from within after being in the DK's mummified army solider's body for a short while she just gives up that easy and joins the DK.

Noob Smoke's Ending

I liked that twist in Noob Smoke's ending. I could understand why Noob Saibot killed his younger brother. Noob Saibot saw Sub-Zero as a major threat and he was also tainted when he became a wraith. I did not understand why Smoke assisted in the slaying of Sub-Zero. Smoke was closer to Sub-Zero than Noob Saibot was in his life as a Lin Kuei. Sub-Zero was the man who brought back Smoke's memory and human part of his cybernetic being. I thought that was true deception when Smoke held Sub-Zero down and let Noob Saibot blast his chest open.
Ermac's Ending

I also enjoyed watching Ermac's ending. It takes a true warrior to fight five warriors and easily beat them all. Ermac was an evil character in the past but I like the fact that he is good, I also like the fact that he is an ally of Liu Kang's spirit. I hope to see more of the alliance of Liu Kang's spirit and Ermac. Cage, Kung Lao, Sonya, Jax, and Kitana were all featured in that ending and it answered a major question I had been asking since I saw the beginning movie sequence that was leaked to the internet during the summer.
Liu Kang's Ending

Liu Kang's ending had a neat concept to it. I really was amazed on how both his body and mind was fighting each other and that both were at a stalemate. I wonder who was the character responsible for re-animated Liu Kang's body. Also in one of the images shown during Liu Kang's ending you see a figure in the backround shooting energy at Liu Kang's two forms as they fused together, could this possibly be Shang Tsung?

I really need to learn how to type with the new Spoiler content on this site.
