Produced by Impel. The first and only Impel set devoted to DC Comics characters, this set features illustrations surrounded by a gray border on front and character information on back along with trivia questions. The backs also have a couple small images. The base set features the following subsets: Hero Heritage, Villain Heritage, Earth's Mightiest Heroes, Earth's Mightiest Villains, Heroes from Beyond, Villains from Beyond, Great Battles, and Classic Covers. There are two checklists to round out the set. This set has holograms randomly inserted into packs, but they are not numbered. The back of each hologram is the same and lists all the holograms with numbers for the purposes of maintaining a checklist. Therefore, the numbers are used. The entire set along with the holograms are also found in a boxed factory set.
