High end feats that are consistent with presentation. And in the CW, that's difficult.
Look at it this way: if we go by high end feats ONLY, MCU Thor is way way beyond the ability of damn near anyone to hurt, and therefore, to allow that Kurse has hurt him means that Kurse is somewhere well beyond "output of a neutron star."
Kara has done some crazy stuff, but she's failed on MUCH less crazy stuff. Her presentation is "really strong" but she has been outmuscled and hurt by dozens of aliens on the show. Are they ALL "million ton" level?
And Kara isn't in the rumble anyway, J'onn is, and he has no feats REMOTELY approaching Kara's.
