Naruto could develop by learning to control the new powers of Shazam. He might start off clumsy but gradually master them. For instance, at first, he might accidentally break things with his newfound strength, but then he'd learn to be more precise.
Sure is. Shazam is rooted in DC Comics. The comic provided the foundation for the character's traits, powers, and adventures that we see in various adaptations.
The accuracy of the Shazam comic varies. Some aspects are faithfully represented, but in some cases, there are changes to fit the narrative style or modern audience preferences.
