Return of the King
She took over Asgard and stole Odin's power. The fact that she succeeded in invading Asgard and imprisoning Odin cements the fact that, yes, she is, at base levels, a rival/peer to Odin (and Zeus, whose realm she also forcibly invaded). She then took on the energy of her entire pantheon. I mean, at this point, it's clear that she was more powerful than Zeus is at his typical levels. I'm not even sure how that can be disputed?
The Godblast blew a hole through her and had her virtually helpless on the ground. 😐 It didn't kill her, but she was out of the fight and her blustering ramblings don't discount that. I mean, she was weakened to the point where Odin (who was drained of his power) was able to seize her and take what was left by force. Her talking and threatening Thor doesn't take away from the fact that the Godblast completely and utterly messed her up and it doesn't make sense to assume anything else if you read the entire Dark Gods saga by Jurgens.
That's nice and all, but the initial Godblast is going to seriously harm him at the least (no can argue that) and Thor's amps (which go beyond double his physical strength due to the fact that the Odin Force itself is imbued in his gear and courses through his body) are going to boost him to Trans+ level in melee anyway.
In order to make a claim for anything but Zeus being grievously hurt, you'd have to ignore the feats of the Godblast, Thor's gear, and cite some feats of Zeus I certainly never seen to justify it.
