In July 2009 Dark Horse Comics announced at the San Diego Comic-Con International that Shooter would oversee the publication of new series based on Gold Key Comics characters from the Silver Age of Comic Books, such as Turok, Doctor Solar, and Magnus: Robot Fighter, and write some of them as well. Valiant sued Shooter over his moving to write the Gold Key characters for Dark Horse as they expected to get the rights and that he interfered with their ability to license the Key characters by indicating that he would write them for Dark Horse. As of January 2010, Valiant had given up the lawsuit against Shooter. He subsequently wrote the relaunched "Magnus: Robotfighter", "Turok" and "Dr. Solar" series as well as "Mighty Samson", another Gold Key character (that hasn't been picked up by Valiant Comics), for Dark Horse, beginning in 2010.
