I take great offense to Zoom as a character. His power set shouldn't allow him to physically do what he does damage wise, but whatever its DC, they have NO writers there, they need a "fast" villain for the Flash. Ok fine.
Thor utterly annihilates Black Adam. I see now reason for BrB to be here.
It all comes down to Surfer to stop Zoom. Does Surfer have morals on? If Surfers morals are off. Zoom is dead before he even knows it.
