I far as I know, the last time Lucius Fox appeared in the Batman comics was in a Scarecrow storyline just before the earthquake that led to No Man's Land. Unrelated to any supervillainous machinations, Fox had a stroke (or was it a heart attack?) and went into a coma. I remember waiting for the resolution of that situation.
I don't think it ever came. To my knowledge, comic book Lucius Fox still lies in a coma six years later while cinematic Lucius Fox takes home six figures. [Please correct me if I'm wrong; I'm worried about Lucius!]
How long will it be before we see Lucius Fox in comic books again, and will his coma be remembered?
