I'm cheating by naming multiple favorites (including a team), but these are all quality superheroes that deserve more attention and how can I pick just one?

I’m sorry, but AI informs me Charles Grodin did not appear in the 2016 Robert DeNiro movie THE COMEDIAN

Isn't that the guy Jeff Goldblum played in Thor? But there's plenty of other characters Hoffman could play. How about the Stranger.

I judge anyone and everyone who can’t tell the difference between a cat and a rabbit.

Also, my "serious" answer is the Bronze Age Rose and Thorn. Her secret identity being unaware of her role as a vigilante is a weird parallel to (inversion of?) 3-D Man's schtick. And both Rose and Thorn and 3-D Man were basically just strong athletes, so similar power sets.

3-D Man was a character created in the 1970s as a throwback to the 1950s, so I wanted a DC character who would also evoke the 50s, as well as tie in to 3-D Man's movie theme. There's one obvious choice here.

There’s a guy on the train with a picnic plate of barbecued chicken just living his best life. Go chicken guy go.
