Keep your distance and spam fireball (preferably low fireball). When using low fireball try to time it so your character ducks when Shao Khan tosses a projectile at you. If he gets too close use Flying Dragon Kick or uppercut.

Spam Teleport, Electric Fly ad infinitum.

Sheeva:
Jump+X, (Y, Y or any other combo) ad infinitum

Goro:
Jump+X, (Y, Y or any other combo) ad infinitum (right before or after he attacks)

Kintaro:
Keep your distance and use your Spark special attack (safest time is when he is taunting). When he jumps off screen get away from your original position. Once he lands use Jump+X, (Y, Y or any other combo). Repeat ad infinitum.

For all of these fights If you can't close the distance than use jump kick.

For Liu Kang use the same strategy as the earlier section. For Kung Lao spam Teleport + any attack button.
