Trivia

 * It is very much similar to the Suicide Squad Gold Pack, the Dawn of Justice Gold Pack, and the Wally West Gold Pack in that they all have a chance to obtain the character (Batman/Batman Ninja, and Lord Joker/Batman Ninja in this pack, The Joker Unhinged/Suicide Squad for the Suicide Squad Gold Pack, Batman/Dawn of Justice for the Dawn of Justice Gold Pack and The Flash/Wally West Rebirth for the Wally West Gold Pack) displayed on the pack. However this pack costs 250,000 Power Credits while the other 3 only cost 135,000 Power Credits.
