After hours, Potts continued to write and produce occasional art for Marvel. He created the "Last of the Dragons" serial which appeared in "Epic Illustrated" #15–20 (Dec. 1982–Oct. 1983) and was written by Dennis O'Neil and inked by Terry Austin. In 1983, Potts teamed with Alan Zelenetz and Frank Cirocco to co-create the series "Alien Legion", conceived as "the French Foreign Legion in space." Two ongoing series and several miniseries and one-shots were produced. In 2007, Potts' "Alien Legion" screenplay was optioned by producer Jerry Bruckheimer and The Walt Disney Company. Bruckheimer exercised the option and bought the script in 2010, hiring "Game of Thrones" show runner David Benioff to do a rewrite.
