Haha no. Just, no. So sad that's the impression of WW people get from the DCEU. Bullshit Zeus baby daddy demigod nonsense. But even going with your example, you know what the Z in Shazam stands for? Zeus. How is Billy stronger than Diana if he gets 1/6th of his powers from Zeus, but Diana, presumably, get's 1/2? That math aint mathing. I guess we'll see how this power ranking goes in Shazam 2 since WW and other Greek goddesses are in it.
Regardless, she's been crippled by the Zeus origin and I hope it goes the way of the dodo after The Flash's reset or whatever.
