Brian

"Brian" is Teen Titans Go! Season 2, Episode 3b (29b), and the 58th overall episode of the series.

Summary
When the Brain captures the Titans to fuel Project B.R.I.A.N., the Titans' Little Buddies are the only heroes who can save them.

Plot
The episode starts when Beat Box and Birdarang arrive in the living room with all the lights shut down but it suddenly turns on, revealing it to be a surprise birthday party specially made for the Little Buddies by Pain Bot, Super Robin, Dave and the Titans. As they celebrate in joy, music and dance, the Titans receive a crime alarm and goes out to their mission, Cyborg tells the Little Buddies to keep the party going while they're gone.

Eight months later...

As the Little Buddies are enjoying the party, the Titans were locked up in a cell with electric bars and the Brain arrives to check on them. Robin was so confident that they will escape anyhow since Brain took away their powers for his secret project in development. When Beast Boy yells at him as "Brian," the Brain corrects him and leaves. Robin decides to do another escape plan which involves Beast Boy in it but eventually it fails as Starfire mentions that every time they are trying to escape, they get tortured by painful electricity.

Back at the Tower, during the party, when Super Robin sees the distress signal, he figures out that the Titans were captured and orders the other little buddies to go in action. The Little Buddies arrive at the Brain's HQ building on the roof where Super Robin tries to fight against Monsieur Mallah but he fails and the rest of the buddies get captured as well. On the other hand the Titans are used to live in their cell except for Robin who tries to reach for the cell's command panel and without any knowledge of what's inside of it, his arm gets crushed resulting for him to scream in pain, getting the Brain's attention and tortures the Titans again with electricity. The Little Buddies finally team up and defeats Mallah, as they reached to the main laboratory after fighting off the security guards. The Titans are still waiting for a miracle to escape while Robin is digging for a tunnel with a spoon. Eventually, the Little Buddies arrive to rescue them but their moment is being interrupted by the Brain whom his project B.R.I.A.N. is complete by placing his head in a giant robot filled with Titans' powers. Beast Boy now corrects his misspelling for being called "Brian" and not B.R.A.I.N.

The Little Buddies are fighting against him but they all get defeated except for Birdarang who transforms himself into a enhanced fighter after Beat Box tried to defend him but got hit. While fighting, he finally throws his head as a boomerang, breaks through the Brain's power cells and kicks his head out of the robot which causes the robot to fall. All the powers are free and return back to its own Titan which eventually escaped at last. As they reach for their fellow Beat Box laid down on the floor, Cyborg places some new batteries which it turns on again with music this time. The Titans and Little Buddies are celebrating their victory, except for Robin who was left behind in the cell still digging with his spoon.

Trivia

 * Silkie, the Universe Staff, and the Demon did not appear in this episode with the other little buddies.
 * The Brain is the first villain in Teen Titans Go! to successfully capture all the Titans. Brother Blood came close in "Waffles", but was short by two Titans.
 * This is the first episode of the second season with the Titans' Little Buddies.
 * The Brain and Monsieur Mallah are the first two members of the Brotherhood of Evil to debut in an episode of "Teen Titans Go!", though both they-- along with Madame Rouge and Phobia-- appeared in the comics first. General Immortus only made a brief cameo in the comic, but not with the rest of the team.
 * Two pieces of music can be heard that sound very similar to real-life pieces of music. The first song, playing when the Little Buddies and the Titans were partying before the crime alert, sounds similar to the 1974 song "Hollywood Swinging", by Kool and the Gang. The song that played when Cyborg switched the batteries in Beat Box (albeit Beat Box stayed "dead" due to one battery being upside down) sounds similar to the 2006 song "Dead Reckoning", by Clint Mansell.

Continuity

 * The Little Buddies were previously featured in "Little Buddies."
 * Beat Box and Birdarang were created in "Power Moves." This episode takes place one year after that episode and shows their birthday.
 * The Super Robin debuted and gained his acrobatic abilities in "Super Robin."
 * Pain Bot was first introduced in "Waffles" and became the Titans' ally and a little buddy after the events of "Little Buddies".
 * Dave was first seen in "Little Buddies". It is unknown how Beast Boy obtained him.
 * Also, attacks Robin in the same manner he did in that episode.
 * While celebrating his victory, Beast Boy dances the same way he did in the previous episode, "I See You."
 * Deaths become prominent again in the second season, with Beat Box being the first to die.

Running Gag

 * Beast Boy mistakenly calls the Brain "Brian." When the Brain reveals the name of his Titan-powered body, it comes out as Brain's Robotic Indestructible Armor Nexus, with the Brain himself mistakenly pronouncing it as "B.R.A.I.N." and Beast Boy ironically correcting him in that it spells "B.R.I.A.N."
