Billy Batson is but a young 10 years old boy when one day a wizard named Shazam came to him, saw in Billy's soul the potential to be his new champion. When Billy accept the Wizard's words, Shazam gave him the Power of the Word, thus all Billy has to say is to scream the word SHAZAM: he transforms into a powerful super hero! The world's mightiest mortal is born! As Captain Shazam, Billy has to protect the world against Black Adam and the Seven Deadly Sins!
Okay so Billy was getting his rear kicked since he was fragile and heck a tiny smol boi.
