Zig Zagged: One movie uses the name Grass Man, but the sequel never does.
Averted: He's called Grass Man throughout the entire film once becoming a superhero.
Enforced: Executives argue that no one is going to take a character called "Grass Man" seriously.
Lampshaded: "I'm lucky this isn't a comic book, otherwise I'd probably have some really embarrassing nickname!"
Invoked: Steve spends days trying to think of a codename, but decides that just using his real name (or no name at all) is much better.
Defied: The second Steve gets superpowers, he immediately proclaims his codename and never lets anyone forget it.
Reporter: "Steven Ulysses, a man with extraordinary abilities but refuses something as garish as a comic book codename..."
Conversed: Two characters talk about how calling him Steven Ulysses is boring, and that they wish he had the name he had in the comics.
Deconstructed: Steven Ulysses chooses not to use a codename like in the comics, but this leads to him accidentally letting his real name slip at some point and ruining his Secret Identity.
Reconstructed: ...But that decision pays off anyway, because he gets far more public trust and support from people who know he has nothing to hide.
Played For Laughs: Steven Ulysses calls himself "Brass Man", "Crass Man" and even "Ass Man" at various points, but never the name he's known as in the comics.
Played For Drama: He used to have a superhero name, but after he became a laughing stock and lost all credibility, he retooled himself as a much more no-nonsense, Darker and Edgier hero with no codename.
