Announced to be one of the last sets of the Justice League Unlimited at the 2012 International Toy Fair, Mattel made this set, which included Wonder Woman and Batman along with the never-before-released Mongul figure, available for purchase through their Matty Collector online store. The original version of Mongul revealed at the 2011 Toy Fair Mattel Collector's Event was painted with a pinkish skin tone, which Mattel was able to change to a more appropriate yellow tone when the set went into production.
