Batman

Batman is a superhero and Robin's mentor, who also thinks of him as a father. He was often hinted in the previous Teen Titans show, but finally makes his debut on Teen Titans Go! His first official appearance was in the episode La Larva de Amor. He was seen fishing with James Gordon, the police commissioner of Gotham City, in a boat that has a picture of Batgirl on it (who is, coincidentally, Gordon's daughter: Barbara). He was also seen in the episode Girl's Night Out where the girls pass by a cop car with him and Jim Gordon laughing randomly. They don't seem to care that the girls are being pursued by much of the JCPD and just continue laughing.

Batman, like many DC superheroes and villains, makes up a huge popculture-like influence throughout Jump City. His image often appears in various paraphernalia such as posters, movies, magazines, and even his own cereal brand. Batman's influence is most prominent in Robin's room in Titans Tower, where majority of Robin's decorations are linked to his old days as Batman's sidekick.

Trivia

 * Batman was only hinted to in the original show but now his name is outright spoken and makes side appearances.
 * The makers of the show have rumored that they want to have Kevin Conroy (voice of Batman in many things including Batman: The Animated Series, Justice League, Justice Leauge: Unlimited, Batman Arkham City, the 2013 video game Injustice: Gods Among Us, and many more) do a speaking role for Batman sometime, although it is unsure when, if ever, this will happen. Batman seems to work with the Titans, often calling them.
 * Batman is a running gag in the series as he makes a cameo in many episodes.
