Hmmmmm, 'Shining light' by the Eurythmics? (C'mon, how was I supposed to resist?) Hell, Ash's cover of the song starts of with a visual that bears an eerie resemblance to the Lightbringer logo (though vocally it resembles the original song less than it does a cat with a terminal case of throat cancer getting hung with a rope made of broken glass.)
On a related note, with all the stand alone animated films DC and Marvel are churning out these days, you have to wonder what a voic cast for Lightbringer would sound like, either in terms of who to cast or just the quality of their voice.
Lightbringer: Christopher Daniel Barnes
His take on Spiderman in the 94 animated series sounds about what I'd expect for Carter. Tough and charaismatic, but also with a stronger hint of vulnerablity than what you'd expect from someone playing Superman, with more of an everyman feel given his anxities of his parents.
Crane: Michael Hogan
Hogan's voice has a certain friendliness and paternal feeling, which fits his genral demeanor but also has a sense of grit and world weariness. Plus he has a darker side, something that Hogan showed in Battlestar and Mass Effect 2 which kind of fits with the hints about how far he wnet to deal with his family's murder.
No particular actress's come to mind, though I sort of imagined her having a New York accent for some reason, basically something that could sound warm and friendly when she's in a good mood, but harsher and tougher when provoked.
Darkbringer: Douchey Mc Nitpick.
