i was playing rumble roses and fable a couple days ago and i thought this might be interesting to maybe see in mk9. hope you enjoy and feel free to comment your opinion on this matter.

alter ego - (note this feature was in rumble roses for ps2) here's an example. - say you play scorpion and you decide not to do a fatality on your friend/or computer the next time you fight you may grow wings or etc. it may alter the look of your fighter and may grant you new moves to which ever character you are playing. sorta like a reward systom for being good, evil, or neutral. it would change the story for that character depending on the choices and actions you perform in the fights.

decison making/reaction to the people around you. - (note this feature was in fable lost chapters) here's an example - say there's a konquest mode in mk9 and you decide to keep the cash for yourself your reactions to the people would be different. this could cause different poses and taughts for who ever you may be using in konquest. then when you fight in a vs match online or offline the character would have the adjustments added to sub -zero or whoever your playing as.

here are a few examples for various taughts for each choice.
dark raiden/raiden (evil choice) - may the gods have no mercy on you.
raiden (good) - i will always serve and protect earthrealm.
raiden/dark raiden (neutral) - i am the thundergod!!!

this could be interesting to see because then we would not have the same taunghts,moves, and animations for returning characters and could be a breath of fresh air. what you think.
