The Creator!
Who was Dave Cockrum? Dave Cockrum created (among other things) The Futurians.
He is also listed as being the co-creator of the New X-men. Of designing Wolverine's iconic unmasked look. And injecting
new life into the Legion of Super-Heroes with innovative, spectacular designs for their costumes and their world.
That's the "official" statement. The "legal" statement approved by lawyers, coroporate execs and the like.
To my mind, Dave Cockrum created a whole lot more that that. He was greatly involved in the first Wildfire story and
designed his costume. So I'm counting that as a co-creation.
He created the look of the Star Jammers who have had their own mini-series and are an integral part of the X-men
franchise.
Like-wise, the Imperial Guard (who I'm surprised have never spun off into their own series).
The Black Cat's look sprung from his voluminous sketch book.
And most notably, redesigning the costume of Ms. Marvel. A design that far outlived her actual series.
These are only the things I'm aware of. I'm sure he's responsible for much more behind the scenes.
While these accomplishments are enormous and their effects on the comics industry cannot be calculated, they are not
his greatest achievement.
To my mind, Dave Cockrum's greatest achievement was remaining a nice man in a not-so-nice business. In an industry that
seems to value cynicism and rewards contempt Dave Cockrum owns a legacy of decency. And that's something no one can take away.
