Technically Billy was an adult and got killed before he became “Shazam”Going through some dc movie. Justice league war, Justice league apokalips etc. and say DC really made Shazam a lot weaker.
Even outside of that 2 show Shazam feels like he is even a lot more weaker than Diana.
But some how they retain Black Adam as almost equal to Superman.
:sips: even in injustice Shazam got fodderize by Clark, but Black Adam is basically able to still fight Clark.
But yeah, they do Billy dirty all the time
