The Bizzaro Titans are a superhero team that consists of five super-powered teens that are dedicated to protecting their bizzaro city as they made their debut in the "Robin Backwards" episode.
Nibor is the team leader. For a brief while, Nibor left the Bizzaro Titans, at the request of the other members, who were not happy with Nibor's laziness, and how he did not regularly train them. He comes to Jump City, where he is "saving" (not really) citizens from a fire, and meets Robin, and the other Teen Titans. Eventually, Nibor comes to Titans Tower with everyone, and the Titans aside from Robin, begin to like Nibor, since he is the opposite of Robin, who is pushy, and bossy with the team. Nibor then replaces Robin as the Teen Titans leader for a short while, with the approval of the four other Titans. Later, once even the Bizzaro Titans couldn't handle Robin anymore, they come back to Jump City, where Nibor learns the Bizzaro Titans really do care for him, where he gladly resigns as the Teen Titans leader, and goes back to his old team, where he kisses Erifrats just before "flying" away in a plane with his team back.
After being replaced by Nibor as the team leader of the Teen Titans, Robin then decides to visit Bizzaro World, where he finds Nibor's team. Robin instantly likes the team much better, as they all are willing to work-out and be respectful towards Robin. It is only until Robin forgets the rules of Bizzaro World, which everything he says to the team, means backwards to them, ends up coming out as insults, rather than compliments, which anger the Bizzaro Titans. The team got tired of Robin, eventually reuniting with Nibor at Titan Tower, with an injured Robin on the field.
Erifrats is an overweight version of Starfire. She has no manners, and does not take care of her outward appearance. She, along with Grobyc, Nevar, and Boy Beast, were happy to have Robin as a new leader, since they were wanting to be trained, and put to work. She, just like the rest of the Bizzaro Titans, also got tired of Robin's compliments towards the team, and finally going back to get Nibor as the old leader, who upon reuniting, she kisses.
A more human version of Cyborg, Grobyc is thoughtful and quiet, unlike Cyborg. He is also mostly a human, with only half of his face being robotic.
Nevar is the complete opposite of Raven. She always smiles, has a great attitude, and has a great sense of fashion. She, just like the rest of her team, took a liking towards Robin at first, who gave the team some structure, and work-out regimens to practice with. Since Robin was complimenting the team too often, she along with everyone else got tired of Robin, and accepted Nibor back as the leader.
Boy Beast is Beast Boy's opposite. He is a genetically altered dog with the power to turn into any human boy. Boy Beast is smart as a whip, and a real go getter. He, just like Erifrats, Grobyc, and Nevar, happily accepted Robin as the new team leader. It is only until they were being complimented by Robin, is when they grew tired of him, and went to get Nibor back.
