She can certainly take it to him physically. (please log in to view the image)

Wondy used the lasso against Omnipotent types all of the time. None of them can stand up to it. What do you think is going to happen to the father of LIES against Universal Truth? (please log in to view the image) (please log in to view the image)
Oh pulease. Mephisto is the father of lies. it's what he does. Mephisto has been punked by The Silver Surfer. The point being, Wondy Routinely resist high powered magical and spiritual attacks. I showed that. She takes it to skyfathers all the time physically and with her lasso. She deflected Nekron, who would prolly kick Mephistos ass. She beat Ares in the Nether World. His own Wrealm. I proved that she can beat Mephisto. Period.
Mephisto is no abstract or Skyfather. Maybe trans. He got punked by the surfer in his own wrealm. Maybe Skyfather but that would be pushing it. Mephisto can't beat Odin or Zeus or hell even DC ares. Etrigan is herald. I was only showing that Hell powers do not harm Diana.
They are nice. I could easily find the scan of Surfer Pnking Mephisto. A Newer story at that. How strong was Galactus? Not that it matters, Galactus got battered around by thing in those days. My pictures are way more convincing. The very fact that you won't acknowlege that she has beaten mephisto types many times matters none. You probably didn't even know she had that many feats. And I didn't even post them all.
Your abc fail logic is against board rules. Oh by the way, make a warlock vs. galactus one too since you have stated t warlock has beaten mephisto. Which All I did was show that Wondy has comparible feats to Warlock.
