Name them?
GL, Aquaman, Batman, MMH, SM, GA, nor sinestro, not lobo, not cat woman (I've seen on their boards they believe so), not any cast member. So if you're going to name one, I do expect a reason why.
For the GL MU if you guys block low and anticipate the lifts, you'll catch him once. And remember Wonder Woman only needs 1 hit for a combo that 4-way resets the situation again.
For the MMH MU, the only real threatening things to keep you in check are teleport and trait. If you walk forward during his OH teleport you can punish it hard (and no one really tries to use the other unsafe version, so it's good for a couple of tries). Wait out his trait and use IADG when he's approaching (or d12). You'll see that MMH isn't that scary at all when you're patient.
For batman, d3, push block bats, the end.
Aquamarine is a tough guy but his wake ups are absolutely terrible. Get one knockdown (or d3) and hit the offensive hard. Mix everything up. Nothing should happen twice in a row without a purpose. From mid screen you can punish a lot with IADG at varying heights.
