In the original Mortal Kombat, if you defeat the last opponent before Goro with Liu Kang, whiff Liu Kang’s fatality by performing it from fullscreen, and then keep walking forward, you can prevent Goro from appearing until you stop walking forward.

Once you let him appear he always does a long pose. You’re not supposed to have control of your character during this time, but in this situation you will, so you can easily let him fall down at about the 5-second mark and get a hit in as time expires to win the round.
