I can only answer for the MKD glitches.

Your picture is a screenshot of Liu Kang doing his possession fatality against ashrah. Yet here is the glitch, Ashrah does her Hara Kiri at the same moment.

The result is beautiful and in this case freaky.

Try it out some time. Check out JFCalibur's threads and downloads both from filefront, youtube, and other forums on this site. The videos selected show glitches for the games as well as some combos.
