If Mokap's not going to return as a playable character, would anyone be fine with him making a cameo as "uncle" Mokap (not biolgically related, duh)? Just some brief interaction with Cassie. He could be the first guy Cassie ever hit in the balls, though I think Kobra would be much more deserving.

In fact, characters who don't return could make cameos, like in MKD's Konquest mode. We could get a flashback scene of Cassie breaking up with her first boyfriend, a jerkoff who looks and sounds like Kobra, who tries to get physical with her only to get hit "down there". Johnny would congratulate her for mastering the low blow. That could even be a playable training segment for Cassie.
