[DC] How does Shazam not instantly reveal his secret identity when introducing himself?
gpt
The wizard is Shazam, and saying his own name does not trigger a transformation.

Captain Marvel uses the word "Shazam" to trigger his transformation. This has led a few people to mistakenly think Shazam is his name, but it's really the Wizard's name.

Captain Marvel Jr., on the other hand, used "Captain Marvel" as his transformation word, which led to a bit of confusion as he couldn't exactly introduce himself. This is corrected in some future timelines where he refers to himself as "King Marvel."
