Before the Black Series, Hasbro had plans to release a line of 6-inch action figures as part of the Episode I as shown in the 2000 Hasbro Toy Fair catalog. This assortment was planned to include Darth Maul, Qui-Gon Jinn, Obi-Wan Kenobi & Destroyer Droid.
Ultimately line was cancelled and most of them were later released as part of the Power of the Jedi line as the "Mega Action" assortment. However, the Qui-Gon Jinn figure never made it to production.
I have seen preproduction items for this line. If you have any, please feel free to showcase them here!
