Stream cartoons Justice League Episode 47 Wild Cards Taking over a TV station in Las Vegas, the Joker announces that he has placed a series of bombs that will destroy the Strip in twenty-two minutes and fifty-one seconds if they are not stopped by the Justice League. With the whole world watching Joker’s version of reality television, the League must first get past the Joker’s own super-team, the Royal Flush Gang. However, the threat imposed by the Joker is not as simple as it seems, and Batman must track down his location to stop his nemesis. This episode is notable as a ‘hidden crossover’ with Teen Titans, as the Royal Flush Gang is voiced by the five principal actors from that series (further, the gang’s designs are based on the Teen Titans voice talent themselves). The episode also features the confirmation of Green Lantern and Hawkgirl’s romantic relationship with a kiss to conclude the episode.
