Actually, in one of Black Adam's earlier origins, SHAZAM ADMITTED that he couldn't harm Black Adam. What did he do? He teleported him away to the farthest reaches of the universe. The result? It weakened the hell out of him. Black Adam would travel faster than light to get back, but he did.
Really shows how durable the Marvel and Adam family was.
