Here is my input.
- Superman vs. Kabal. Kabal wins because of instant aerial gas blasts. But if Superman had Mortal Kombat's movement, he would win. Superman has Jax's corner damage and f+2,3 jails every character unlike Jax's f+4,1,3.
- Black Adam vs. Kung Lao. Even match, which would be highly aerial based.
- Aquaman vs. Kenshi. Kenshi wins due to mid range domination.
- Batman vs. Freddy Krueger. Freddy wins because of zoning and the ability to escape corners with EX teleport.
- The Flash vs. Cyrax. Cyrax wins. He does more damage and has access to combo breakers.
- General Zod vs. Reptile. Reptile wins. I think Zod's trait would not track Reptile's elbow dash very well at all.
- Doomsday vs. Johnny Cage. Doomsday wins. He can backdash out of everything Johnny Cage does except nut punch follow ups. He can use trait to close the gap.
- Killer Frost vs. Sonya. Even match up. Whoever establishes their game first wins.
- Wonder Woman vs. Kitana. Even match up. Kitana has much better zoning, but Wonder Woman has superior corner game and slightly better footsies.
- Sinestro vs. Shang Tsung. Shang Tsung wins. Not really sure about this one, though.
Bonus: Pre-patch Kano vs. Pre-patch Deathstroke. Deathstroke wins but not convincingly. Low gunshots would go underneath knives, but Kano can use aerial ball to punish any grouned gunshots full screen away.
