If any villian can do it, he can.
He has a tragic back story which made him UNSPEAKABLY vengeful. He is like Dr doom in the sense that his allegiance is to his nation, fukk everyone else...And when he raged out
World War III
He made the entire world bow down for a week...Probably the biggest non cosmic threat in dc history
I don't know if I like Shazam being broken in two films but it does mean DC will push him in comics I hope. The tone for Shazam can be light hearted and childish fun, because that's what Shazam is, and black Adam can be badassery.
I hope it works, they're both top 3 villians and heroes ever to me.
