That is such a pure comic book plot right there. Anyway, Daredevil still has his own comic book. Gambit might, but he’s still in comic books, even if he doesn’t have his own
As for other Catholic superhoes, one particular version of the Hulk (from the Marvel Ultimate line of comic books) was explicitly Catholic, even being shown with rosary beads and writing a detailed note about his view on the afterlife.
Then there’s Banshee, an Irish X-Man whose Catholicism they make obvious but never make a big deal of. Finally, the Punisher, also a Marvel character (I don’t really know any DC ones), was an Italian Catholic and for a while, the writer had him going to confession regularly.
