It seems unlikely. While some level of cussing has become acceptable in comics over the past few years, there are certain characters for whom it just seems ... out of character. Of these, the most extreme are Superman (whose typical expostulation has historically been "Great guns!"/"Suns of Krypton!"/"By Rao!") and Captain Marvel (who says "Holey Moley" a lot, no doubt in reference to the little-known Coptic hieromonk, Abba Moley of Dendera).
Still, DC is rebooting its entire universe, and strange things may happen. A guy who runs a comics shop in North Carolina thinks that Mrs. Kent's little boy has taken a sudden turn for the profane. Apparently, when being zapped by some sort of ray gun, he doesn't recapitulate his classic observation that it tickles, but instead says, and we quote, "GD." (It's upper case, but comics lettering is almost always upper case).
Based on this, the shop owner has preached a Crusade, and sworn to boycott Action Comics until writer Grant Morrison steps down, or Jerusalem is taken back from the infidel.
Reached for comment by every possible comics-related news outlet, Morrison responded, "it's a grunt."
Which, actually, sounds about right. You get hit by a death ray, you're gonna grunt.
