"Caged Tiger" is Teen Titans Go! Season 1, Episode 17b, and the 34th overall episode of the series.
Cyborg, Beast Boy, and Robin return from their Bro-cation and are closer than ever, but their bro-mentum is interrupted when they get trapped in the elevator.
A quiet afternoon filled with reading in the Tower's living room is suddenly interrupted by Cyborg, Beast Boy, and Robin, who burst into the room, announcing their return from their "Bro-cation". When the girls don't seem to care, the "bros" decide that it is "Bro Broscious Bath Time". Before they even leave the room, the "Crime Alert" alarm sounds, startling everybody. The computer tells them that Dr. Light is loose in Jump City. Cyborg suggests that they take "The Bro Train", and instantly transforms himself into a train. Beast Boy and Robin jump on board, and they all ride to the elevator. Raven and Starfire both decide that they do not want to go along with their stupidity and that they will meet them there.
Inside the elevator, the three bros are pumping themselves up for the mission, until suddenly the elevator stops. Cyborg tells them that it is no big deal, and that he can fix the wiring within a few minutes. Robin comments that they have no signal on their communicator, but he is not worried because he is confident that Cyborg will get them out of there. Beast Boy sighs and shivers, saying he wishes he hadn't "drunk" so much before they left.
Meanwhile, on a rooftop in Jump City, Starfire and Raven arrive to find Dr. Light's gigantic weapon already in place. The villain prepares to blast them, but stops, and asks where the others are. The girls assure him that the others will be there soon, and Dr. Light ask the girls if they will be willing to wait. He assures them that it will be much better with all five titans present. The girls decide that they will wait like he asked and all three sit down.
Back in the elevator, Robin begins to freak out, and states that he is like a tiger, and you should not cage a tiger. Beast Boy tries to get his mind off of his situation by asking Robin how he and Starfire are doing. Robin tells him that she touched his arm six times that week, which means that they are practically dating. Cyborg finally finishes the elevator, and puts the two wires together. Instead of going down, however, several weapons come out of the ceiling and wall, and blast away at the "bros". Cyborg becomes furious that Robin took the time to install a security system to the elevators, and tells him that it will take longer than he thought.
Back on the rooftop, Dr. Light asks Raven if she has heard from the others. She assures him that they will be there soon, and continues reading. Starfire asks the him how he got his name, and he says he will only tell if they promise not to laugh. After they promise, he screws two light bulbs into the side of his helmet, and they light up when Starfire pulls his finger. The girls compliment his astounding trick, and he asks them if they wanted to get something to eat.
In the elevator, Robin asks Cyborg if he is about finished. Cyborg tells him he would have been finished a while ago if it hadn't been for the junk Robin installed. The two break out into an argument right as Beast Boy decides that he cannot hold it any longer. Robin and Cyborg both try to convince him to hold it, but he has made up his mind. Before they know it, he is finished, much to their disgust.
We flash back to the city, where a lot is going on. Ed is robbing the diamond store again, and Dr. Light is at the Justice Java cafe across the street, on a "date" with the girls. Before Raven has a chance to pay the bill, Dr. Light insists that she let him pay for it. Raven tells him that he is not actually as bad of a guy as they thought he was. Dr. Light tells them that he can show them his dark side if they want, then he asks them if they want dessert.
In the tower's elevator, Robin is finally starting to snap; he becomes convinced that he actually is a tiger in a cage. Cyborg is also starting to freak out, and starts to yell at Robin for being annoying. Beast Boy insists that they both just relax, and Cyborg begins to lecture him for "relaxing all over the floor". Cyborg tells him not to call him "bro" anymore, and angrily continues to work on the elevator's wiring. Beast Boy transforms into a humming bird, flies up to Cyborg's ear, and whispers "Bro-ho-ho-ho-ho-ho!".
Cyborg finally snaps, and aims his arm cannon at Beast Boy, encouraging him to call him "bro" one more time. Beast Boy tells him that he "still has stuff left in the tank" and he is not afraid to use it. Robin tackles both of them and pins them on the floor. He tells them that his tiger claws are out, and immediately begins to claw them in the face. This angers the other, and starts a war between all three "bros". Cyborg aims several missiles at the two as Beast Boy transforms into a rampaging gorilla. Beast Boy and Cyborg tackle each other and Robin starts to bite Cyborg's foot. Cyborg kicks Robin off, and he smacks into the open wiring. After he is painfully electrocuted, the elevator turns back on. Cyborg congratulates Robin on fixing the elevator, but Robin insists that the credit goes to him. All three "bros" crowd together in one big group hug.
The girls and Dr. Light return to the rooftop, each of them are licking an ice cream cone. Raven asks Dr. Light what he was going to do with his invention and he tells them that he was going to use it to disintegrate all of them. He decides shows them another feature, which lights up the sky in an incredible light show. The girls tell him it is very pretty. Dr. Light finally realizes that it feels "good" to be good. He decides that he will give up his life of crime, and asks the girls if he could become a Teen Titan. Starfire tells him that would be wonderful and they would love to have him. Dr. Light makes a solemn vow to, from that day forward, only use his light for good and entertainment purposes. Before he can finish expressing his excitement, Robin jumps up and punches him in the face.
Robin wittingly tells him that he the rest of his life will be spent behind bars, and starts violently beating him with his staff. Starfire and Raven both beg Robin to stop hitting him, but before they can explain why, Robin hits him with a body slam. Robin moves out of the way so Beast Boy can have his turn fighting the villain and transforms into a llama. He begins to bounce up and down repeatedly, critically injuring Dr. Light. He continues jumping as he changes into a gorilla, then an elephant, then a whale. Cyborg approaches the villain for his turn, and transforms his arms into battering rams. He begins to pummel Dr. Light at an intense speed. Then suddenly, his shoulders transform into rocket launchers, and fire several rockets simultaneously. Then a gigantic cannon pops out of his back, and blasts away the almost-crippled doctor. Almost dead, Doctor Light tells them that they will pay for this, and swears vengeance against them. Starfire and Raven immediately rush to help him, hoping to save their friendship. Cyborg, Robin, and Beast Boy once again jump into "the bro train", and the episode ends with them riding around in circles.
