So I'm imagining a French superhero changing his clothes in an invisible telephone booth, pressing up against the walls in mime-like fashion, trying to figure out what to do with his baguette of bread in that small confined space.

What would a French superhero be in "real life"? A 'mild-mannered policeman for a great metropolitan police force', which would explain why French cops never go after Muslims?

And how would a French superhero fight a "never-ending battle for truth, justice and the American way!"? Especially since the FRench don't believe in truth, have no justice, and are committed to being un-American whenever possible. 'tis a puzzlement.
