I played Alioune's Cyborg last night, and I think the matchup is like 6-4 to Cyborg. I won 1 match and lost like 15 with Aquaman lol. First of all I have never fought a Cyborg of that caliber before Alioune, so it took sometime to "adapt", but even then it was really hard.
I started to understand where I could dash to gain space, and when to trident, but even when hitting with trident, there is most likely a projectile in the air on the way towards you, so you will trade and Cyborg can start zoning again. I would also try to use the water shield to deal with the fireball zoning, but it didn't really get my anywhere. There is always a fireball on the way towards you, so even if you absorb a few, there is anotherone waiting when you dash out. Also, his missiles does damage to you even when you have your shield out.
I do see the potential when Aqua finally gets in though, but you need to capitalize on the openings you get every time, because if you don't Cyborg has a string that pushes you away and is safe, and also his grapple that is invincible until the end (armor?) and he can attack/fireball out of it, so a lot of the time it is a free escape from the corner if you get too close without being ready for it. He also has an uppercut like wake up move, so be carefull to pressure him on wake up.
The reason why I lost 15-1 but think it is only 6-4, is because I got too desperate and dropped stuff when I got close. I also think it's extremely important to be aware of your combo choice and always end it with Cyborg between you and the corner. I wasn't able to do this because it takes its toll to fight your way in for 40 sec. and I get desperate.
It doesn't help that my execution for the air trident toss is like 50% at best (I hate the precise input for half circle forward, and I need SF controls to do d1 without getting accidental special moves lol)
