i all ready made post for this but my idea was to get nick scyer from Psi-Ops: The Mindgate Conspiracy in it

And why him?

Because he's probably the best character that Midway has outside of the MK Franchise, which is kind of sad since their selection is so limited. Nick Scryer is cool since he's got a bunch of psychokenetic powers. It lends him to alot of cool power possibilites. He's also a Special Ops agent so he's probably skilled in Hand to Hand. All things considered, he might be a cool guest character in MK, even just as an excuse to use him again. But then, you might also consider characters from Unreal Championship coming to the MK series in some completely idiotic way.

No.

I don't care who it is, there should be no guests. MK has a complex story behind it and we don't need guest characters there for the sake of filling spaces or just because someone wants them there. It'd mess witht he story and most characters wouldn't fit within the world of MK. even some of the MK characters themselves don't seem to fit. It'd be tampering with one thing and going a little too far. It's bad enough we get filler characters with bad moves, Fatalities and stories. We do not need to have time that could be used on perfecting anoother character and space taken up by a character that doesn't need to be, or has no business being there.

just like SmokeNc-017 said

I wouldn't mind seeing Anubis from Unreal Championship to make a guest appearance, but I guess it's unlikely.
