Not the Milkman.
yes but as deathstroke you can discourage them from throwing it because you can react to their jump and shoot them out of it. if they throw it to you after a hard knockdown you can always spin or flip since they have like 600 invuln frames as wakeups and you wont get clipped. you dont really have much to discourage them from using the water in atlantis outside of MB f3/b3 and if you're out of range for that, its a dick.
It's pretty hard to be out of range for a punish on the fishtank. Power characters stand there for FOREVER. You just have to eat 1 hit with your MB F3, then you have time for 2 dashes and a 132 combo. Also, the turret OTGs when thrown, so it beats wakeups (it'll hit you before you can even wake up).
