Its a full combo for either player, you could always just stand there and do nothing, which is actually a pretty good option tbh.
BA has a similar weakness to Reptile, if you can get him within a certain distance he can't jump at you, cant hit you with normals and cant divekick.
I see what you're saying though, but he could have an Aquaman backdash and still escape most shit if he backdashes after a divekick, so you'd still have to dash forward after him anyway.
Maybe, maybe not. If he had Aqua backdash, that might open up the possibility to chase him down with some normals after divekick. But really, its not just after divekick that this is a problem. He can pretty much backdash away for free after any safe move. And on top of travelling like 2 miles backwards, he recovers from it so damn fast that he can almost always punish you for whiffing afterwards.
BA backdash makes Shazam a sad panda.
