Greg Rucka is one of those freelancers who has been screwed not just by DC, but also by Marvel. For DC, he created one of their top-selling titles: Gotham Central. The comic didn’t sell well, but the trade paperbacks are a license to print money, selling out year after year. But DC summarily dismissed him from several projects, including a Wonder Woman project when DC decided they’d sell more copies if Grant Morrison wrote it.
Then, at Marvel, Rucka did a great job re-energizing Punisher. Not since the early Matt Fraction days had Punisher run in the mainstream Marvel Universe—and Rucka put him there, solidly, in a way that made sense. For his troubles, Marvel cancelled the book.
