Peter David
From Superdickery
A writer of Star Trek novels and possibly the only comic book writer to make Aquaman something other than a drip. Also wrote the version of Supergirl where she was an Earthbound angel instead of Superman's cousin. He wrote Young Justice which is remembered as a time when certain teen heroes were tolerable and has a bit of a cult following on SD.
Responsible for X-Factor, which by itself would make him among the best comic writers ever.
