Back to list of episodes

Divide and Conquer is the first episode of the series and season one. This episode is often referred to as episode 3 because it was the third episode to air on TV, and Final Exam was the first episode that aired on TV. However, this episode was the first to be produced.


After a battle with Cinderblock, Robin and Cyborg get into a fight causing Cyborg to leave the team. Meanwhile, Slade causes trouble by releasing an evil monster named Plasmus.


The Teen Titans are alerted of a break-in to prison by the villain Cinderblock. The Titans arrive there quickly and begin fighting with Cinderblock, although they get beaten quickly. A maneuver by Robin and Cyborg called "The Sonic Boom", intended to stop Cinderblock from escaping, fails when they trip and get tangled in each other. Robin and Cyborg begin arguing with each other scaring the others including Raven. Cyborg, letting his jealousy and rage take over, decides to quit the team because he is tired of Robin always being leader and blaming others for his mistakes. Meanwhile, while they are arguing, Cinderblock punches through the walls of the prison, freeing some of the prisoners eventually reaching a high security room. Cinderblock reaches in and grabs a stasis with a sleeping person in it before escaping into the night while the Titans rally the other prisoners back to jail.

The next day, the Titans are discussing what had just transpired that night. Beast Boy believes that Cyborg should not have gone complaining about it to Robin and even tries calling Cyborg, but nobody picks up. Robin does not care about this at first, although he gradually resents it as he is forced to do all of Cyborg's chores as well as having nobody to play video games with.Even Raven is saddened about Cyborg's departure (though she won't admit it). At Slade's hideout Cinderblock emerges with the stasis tank on his shoulders. Slade congratulates him on his work and then wakes up the sleeping man inside. The man gasps and tells Slade that he shouldn't be awake and begs him to put him back to sleep. Slade remarks "I don't need you. I need PLASMUS!" and straight away the man in the tank begins to transform, breaking the tank and emerging as a gigantic purple monster. Slade then orders Plasmus to consume more toxic sewerage at a waste management plant.

The Teen Titans hear about Plasmus's activities and rush to the waste plant, only to witness Plasmus growing bigger with the more waste he eats. The Titans begin to attack him with all sorts of attacks, but they fail as Plasmus regenerates his body and retaliates by attacking them with sludge. During this time the Titans receive a message about Cinderblock attacking another part of town. Robin insists that the rest of the Titans go while he holds off Cinderblock. Starfire refuses and so do the rest of the team, knowing Robin cannot defeat Plasmus on his own. Raven, Beast Boy and Starfire begin attacking and manage to weaken and seperate Plasmus into smaller creatures, although they get trapped and consumed in Plasmus's parts in the process. Robin falls onto a conveyer belt and fights with one of Plasmus's sludge crabs. He is about to drop into a huge barrel of acidic ooze when Cyborg suddenly appears and grabs his arm, repeating his phrase "I've still got the Sonic if you've still got the Boom". Together they get up and attack Plasmus, who is already reduced to a small sludge monster due to the attacks of the other three Titans. Their Sonic Boom attack, consisting of Cyborg's Sonic Cannon and Robin's explosive disk, destroys Plasmus and returns him back to his human form: a man sleeping on the floor. Cyborg and Robin apologize for their earlier disagreements and agree to become friends again. Robin claims they failed in capturing Cinderblock, but Cyborg just laughs and points at the road, where Cinderblock is being tied up to a truck. He tells Robin he had already defeated Cinderblock and had wanted to show Robin it as a present. The episode ends with Robin suspecting someone is behind all these attacks and Cyborg assures that no matter who he is, he is no match for the Teen Titans.

Back in his lair, Slade smashes down his fist in anger, swearing that "next time my plans will succeed, and the Titans will pay."

  • The title refers to Cyborg's leaving the Teen Titans and their later near defeat (specifically, when Robin is about to fall into the vat of implied acid). However, with Cyborg's return, Slade is no longer able to easily defeat the Titans and they are victorious in the end.


  • This episode is often confused as being the first episode aired, when it was really the third episode aired and the first episode written.
  • Most of the actions in the theme song (i.e. Raven showing up from the other side of the wall, Beast Boy looking somewhere and then turning in to a pterodactyl, ect) appear in this episode.
  • As the first episode in the series, this episode features the first appearance of the main Teen Titans, as well as Slade, Plasmus and Cinderblock.

Memorable Dialogue

  • Slade: [While monitoring how the Titans get roughed up] Disappointing. With one Titan missing, this is almost too easy. I was expecting more of a challenge.
  • Starfire: I am sorry to disappoint you, but I am stronger than I look.
  • Beast Boy: [While Plasmus is chasing him] DUDE, I AM NOT ON THE MENU!
  • Robin: Loser.
    Cyborg: Jerk.
    Robin & Cyborg: WHAT'D YOU SAY?!
    [They grow big as Beast Boy, Raven, & Starfire turn into babies]
    Robin: You have a problem tin man?!
    Cyborg: Yeah! It's four feet tall and smells like cheap hair gel!
    Robin: Well, you're an over-sized klutz, and your feet smell like motor oil!
    Cyborg: You're bossy, you're rude, and you have no taste in music!
    Robin: I don't even know why you're on this team!
    Cyborg: That makes two of us! I QUIT!
  • Slade: Next time my plan will succeed... and the Titans will pay!
  • Cyborg:[after he saves Robin] I still got the sonic if you still got the boom.
  • Slade: [after Cinderblock brings in the human form of the sleeping Plasmus in a capsule] Cinderblock, I see your mission was a success. Good. We will proceed with Phase 2: wake him!
    [Cinderblock opens the capsule which releases some steam and Plasmus wakes up in a horrified way]
    Plasmus: [in human form] I'm awake? I could never be awake! I'm only human when I'm sleeping!
    Slade: But what for I have in mind, your human form is useless. I need Plasmus
    [Plasmus suddenly begins to look like a sludge creature. Cinderblock backs away as Plasmus breaks through his sleeping chamber and reveals himself as a giant sludge monster]
