Punching reality is a little crazy even for Supergirl and Flash. Still think he'll be a one-off foe for both of them and probably not as powerful as his comic book counterpart. However still dangerous.

Black Lightning is something i cannot wait for to have a crossover and all signs point to J'onn being the one to do it.
