Sidekick

"Sidekick" is Teen Titans Go! Season 1, Episode 17a, and the 33rd overall episode of the series.

Summary
Robin gets called back to the Batcave but only as a house-sitter while Batman’s away, and the other Titans show up and tease Robin about his sidekick status.

Plot
The episodes starts inside Titans Tower, where the Titans are hanging out, trying to find a good television show to watch. Robin enters the room with his suitcase, announcing that he has a "secret" mission that he must do alone. After nobody cares, Robin keeps repeating himself, until he is acknowledged. He tells them he will be at the Batcave if they need him.

Suddenly, all of the Titans sit up, excited, begging Robin to take them along with him. Robin turns them all down, and then leaves. After traveling across the entire country on his R-Cycle, Robin finally arrives at Gotham City in New Jersey. To enter the Batcave, Robin has no choice but to mutter his embarrassing nick-name "Boy Wonder" into the microphone.

Eager to start his "special mission", Robin sits at the Batcomputer and fiddles around on DCUBook. All of a sudden, a message from Batman pops up on the screen, thanking him for cave-sitting while he is away, and giving him permission to take juice from the fridge. Beast Boy excitedly exclaims that he would like juice, startling Robin. Robin is horrified to find that he left the Batcave door unlocked, allowing all of the Titans to enter.

In a quick instant, the Titans are running around the cave, screwing around with Batman's stuff. While Cyborg is trying on Batman's belt, Beast Boy is turned into a bat, posing in front of a lamp, and Raven is meditating with some bats on the ceiling. Before Robin can stop their shenanigans, he is stopped by Starfire, who is trying on Batgirl's costume for herself.

After several seconds of being in awe of his crush, he regains control of himself, and decides to stop the Titans before they do any real damage. When he finds Cyborg and Beast Boy, he is terrified to see them staring at Batman's most prized possession: The Ultimate Bat-a-rang. The duo insists on being allowed to use it, much to Robin's annoyance. Raven asks Robin why he is so scared of Batman, but he avoids the answer.

Suddenly, everything is interrupted by a crime-alert alarm. The Titans are shocked to find that, for unknown reasons, the H.I.V.E. Five are terrorizing downtown Gotham City. The Titans rush to collect as many of Batman's gadgets as they can to prepare for the coming battle. Robin frantically trying to prevent the inevitable, but he is too late when Starfire scoops him up and sets him inside the Batmobile.

A short time later, the H.I.V.E. halts their attack on downtown Gotham when they notice the Batmobile coming their way. Thinking that the Dark Knight himself is behind the wheel, each member of the H.I.V.E. halts in their tracks, becoming too scared to move. A dark, bat-shaped figure jumps out from behind the car, and stares them down. The H.I.V.E. members breathe a breath of relief when they realize that the bat-shaped figure is none other than Starfire in her Batgirl costume, and the car is being driven by none other than their arch-enemies, instead of the Caped Crusader.

A battle breaks out, and the nervous Boy Wonder is more focused on picking up the gadgets than fighting the villains. Due to snatching away all the gadgets, Robin accidentally helps the H.I.V.E. win the battle and tie up all the other Titans. Beast Boy realizes that there is only one hope left: The Ultimate Bat-a-rang. Sadly, the H.I.V.E. has the weapon, and decides to use it against the Titans. The villains push the button, causing the Bat-a-rang to beep, and throw it at the Titans.

Robin fails to catch the device, and it nearly decapitates the other Titans. Flying up into the sky, the Ultimate Bat-a-rang explodes, creating a gigantic light show, which lights up all of Gotham City. Everyone, including Robin, is shocked to find out that the Ultimate Bat-a-rang is not a weapon. Robin wonders out loud why Batman would have such a strange device.

The camera cuts to a week ago, where Batman and Gordon are sitting under the stars, watching the light show. Batman and Gordon begin to laugh together as friends. Back to the action, Robin decides he will use Batman's gadgets after all, and quickly defeats the villains.

Later, at the Batcave, the Titans attempt to help Robin clean up the gigantic mess they have made. Robin decides that he is tired of being treated like a sidekick, and that he is going to stand up to Batman, making sure that he knows that he is not the boss of him anymore.

Suddenly, a tall, Bat-shaped shadow walks up from behind him, and Robin begins sobbing, begging Batman to forgive him. He tries to convince Batman that he didn't mean any of it, but shortly after, is embarrassed to realize that he is not really talking to Batman, but a mannequin wearing Batman's cape and cowl that Beast Boy is putting back.

Robin admits he is still scared of Batman and graffitis the words "The Joker was here" on the side of the ruined Batmobile before fleeing the scene.

Trivia

 * Robin seems to be very attracted to Starfire in Batgirl's costume because it basically combines the two people he has a crush on/his two main loves in the comics: Starfire and Barbara Gordon. The fact that, according to Starfire, the costume is tight-fitting on her may have been an added effect to him
