By a rough guesstimate, I probably created over five hundred characters for DC between 1969 and 1985. Most of them were minor one-shot creations, and some of them, like Felicity Smoak (now a regular on Arrow) were minor supporting characters who’ve taken on a new life in other media. Unless I’m willing to commit a large chunk of my life to tracking down each character and filing a separate equity request in anticipation that somehow, some day, one of these characters might end up on a TV show, I risk being cut off from any share in the fruits DC enjoys from the product of my labor. A share which DC acknowledges I’m due– but which DC refuses to assist me in receiving.
But now we come to the catch-22 of DC’s new approach to creator equity agreements. Assuming I perform my due diligence (which should really be DC’s due diligence) and dig up references to characters I’ve created that might soon be appearing in other media (maybe as a chess piece, or a Heroclix figure, or a recurring character on The Flash), and assuming I file the necessary request form in a timely fashion– DC can still decide, unilaterally, that my creation is “derivative” and they don’t owe me a dime.
