Shadow Falls features a roster of twelve fighters: ten immediately playable — the two Double Dragons and eight Shadow Warriors — plus two end bosses. Most characters originate from the Double Dragon animated series that aired around the same time. The only original characters are Bones, Sekka, Blade, and Dominique, with Blade's design based on the generic Shadow Warrior soldiers from the show. Dominique and the Shadow Master are unlockable via code in the Super NES and Genesis versions. The Jaguar version drops Blade, Trigger Happy, and Icepick while adding Dominique to the default roster.
