Unum (Earth 616)

Kismet, of course (being cosmic).

Would Maxima be enough?

Sayd or Scar, being Guardians of the Universe, I would think.

I don't know, Unum was beating up on the Collector off panel, and he could not stop her from reaching her target. The Collector easily defeated a being more powerful than Sersi, so Unum had to have been pretty powerful.

Maxima?
Power Girl?
Kara?
