His intro in the series did it for me.

There's not much out there aside from the Charlton stuff that I've been able to find. There was a 2005 mini that was good (though he's still 'Vic' there instead of 'Charlie'), but it was almost as much a Superman story as a Question story, for better or worse.

The one I really liked though was a Question-Huntress mini from 1999 that Rucka penned. Best pre-Simone characterization of the Huntress, and very good Question presentation. Rucka doesn't disappoint, I think.
