Dinah for now. She's a pretty good h2h combatant, almost as good as T'challa. Plus her Canary Cry is a building buster. Not sure if BP's suit can tank something like that. Especially when Dinah can just spam the cry.
I don't have the feat (so this might be pointless) but I think I read somewhere that her Cry could hit 300 decibels. To people to know a little bit about sound (or can google) that is an absolutely INSANE amount of loudness. The largest ever recorded in human history was just over 300 and was a meteor exploded.
Physical pain for humans starts at 130~. You can go deaf by 180.
For comparison the Kratoa eruption was 180 and was heard as far as nearly 2000 miles away.
Again, I can't give a feat, but if true. The physical vibrations of the noise at 200+ are enough to kill someone. 300 is going to put an enormous strain on T'Challa's suit, though the starting distance is very small.
Prometheus has nothing on team Cap. Even with prep, he is not going to have much to work with. Especially with Blade and Black Cat. And Blade does not have the stats to take on Black Manta. Look him up.
Black Manta has the raw firepower to take out anyone on team one. His firepower is designed to take on Aquaman in the ocean. Underwater. With Mera and crew piling on.
If Team one does not get crushed by team DS, they will win out over the thinned out winner of Team Cap vs Team Terminator. King Pin and Black cat will die in the first volleys. As will Raa's and his assassins, Bane, and Prometheus. Team Bat will lose all of their low tier members. Batman, Damian, Cass, Dick, and maybe Jason will survive the first few moments with whoever wins between team DS vs Team Cap.
A double team is likely given the prep time. In which case team Two will go down to double team. They do bring the most offense and the Talons are like Vampires without weaknesses Blade can exploit. They have three members with enhanced stamina and/or healing. The HF for Team Cap is by all counts less than team 2. The only advantage that Team Bats can utilize is a lot of coordination. Possible overall prep expertise if we count Babs pre 52 feats.
At the end of it all each team has one wildcard heavy gear. Team Cap has Blade. Team DS has Manta. Team Bats has Batwing. Each one has the firepower to trash the low level opponents. But it is Manta vs Blade that will decide it.
Not much to work with? are you joking he has Manta,Slade,Ra's,Bane and Cain to work with all of them are good with prep. A straight up fight will come down to Panther,Prometheus and Azrael(regardless of which vesion).
