"Multiple Trick Pony" is the thirty-fifth episode of Season 2 of Teen Titans Go! and the eighty-seventh episode overall. It first aired on 19 March 2015 on Cartoon Network.
Kid Flash wants to join the Titans, but Robin insists that he can’t because Flash is just a "one-trick pony."
The Titans have a battle with the H.I.V.E. Five again, then Kid Flash appears in, defeating them. The Titans are in amazed, except for Robin, who thinks that Kid Flash is just a "one-trick pony", with Robin himself being a "multiple trick pony"; having a nice butt and a good beatboxer. Back at the tower, Robin tries to exercise for his competition with Kid Flash.
Later, at the race, Robin and Kid Flash does a race. Unforunately, Kid Flash beats Robin several times, and their last match is with Robin on Kid Flash. However, Kid Flash won because he was the one who's close to the finish line. The competition was over, Kid Flash was now the leader of the Teen Titans, and Robin feels so lonely that he lost his four members.
Robin is sad that he saw everything: Cyborg, Beast Boy, Starfire, and Raven give Kid Flash a party, a hangout, and a battle with Cinderblock. But his destiny is that he's still a "multiple trick pony".
The next morning, Robin tries to ask the Titans if he'd get his job back as leader, but they disagree him. They still like Kid Flash better, but Robin gives him one more chance who the leader will be: Kid Flash or Robin.
At the race, Robin breaks Kid Flash's legs with his staff, and he is now unable to walk or use his power of super running. Robin then runs to the race, and, after crossing the finish line, he's got his job back as leader.
