SHAZAM! has the wisdom of Solomon, the strength of Hercules, the stamina of Atlas, the power of Zeus, the courage of Achilles, and the speed of Mercury. So he is obviously a power to be reckoned with.
He is Billy Batson, a rather arrogant kid who has spent his life living with foster families, and who is endowed with all the above mentioned powers after encountering wizard Shazam. In order to gain these powers, he needs to utter the initials of the gods and heroes mentioned above, in the correct order.
As a testament to his strength, we can mention that he is one of the Justice League members who has an honest shot at taking the head of DC’s Trinity, by using his colossal magic powers. Of course, we could also mention that he split a killer asteroid in two with ease – but this means nothing when compared to what will follow.
