The Kryptonians, Mongul and the Kryptonian, Supergirl, Gog, the Infected Justice League while overpowering all of them including Amazo who had the powers of the JLA. Her fts are solid.
Zod and Ursa was a good feat. Nothing wrong about that.
She didn't do much to Mongul and Non was weakened in one instance. The other one was off panel iirc.
Also didn't you recently make a point of Sinestro beating Mongul by dragging him along the ground? He's only impressive as long as he's fighting Wonder Woman?
Supergirl is decent.
Gog was dripping full of magic and had to cheapshot Superman. He basically got beat by hv and a dropkick after a shitload of free attacks. And she almost got ko'ed by him. Beta would have cracked his head in half.
Amazo just got slept last issue by one shot from infected Batman. And the League's powers were being supressed and returning slowly. In fact, about two or three pages back they were effectively powerless.
Yes she has good feats. Better isn't a word I'd use though.
