In Jump City, the Teen Titans arrive to stop the Balloon Man. When he cannot figure out who they are, the Teen Titans jump into a rap song to introduce themselves and become distracted, forcing the Justice League- Superman (Kal-El), Green Lantern (John Stewart) and Wonder Woman- to intervene. They criticize the Teen Titans for being childish, not taking anything seriously, and bring up the fact that they do not have a feature-length Film adaptation of their own to prove their legitimacy as actual superheroes.
