Starfire the Terrible

"Starfire the Terrible" is Teen Titans Go! Season 1, Episode 15a, and the 29th overall episode of the series.

Summary
When Robin needs an archenemy, Starfire generously offers to fill in the role and she far exceeds Robin's expectations.

Plot
The episode opens with Cinderblock attacking the Jump City Railyard. It's Motorcycle Monday, so Robin orders the Titans to hold back unless they have a motorcycle. Robin uses his Motorcycle to easily defeat Cinderblock.

Back at Titans Tower, Robin drives around the living room, deciding he is the greatest hero ever. The other Titans tell him that in order to be the greatest hero ever, he must have an arch-nemesis. Robin becomes very upset (again) and cries, wondering why nobody wants to kill him. Starfire, who hates seeing Robin in pain, offers to become his arch-nemesis. The other Titans only laugh at her, telling her she is too nice to ever become a villain. She attempts to show that she can be evil by drinking milk straight from the carton, but she is unable to do it. Starfire retreats to her room, to find the four things every villain needs: a costume, a henchman (Silkie in robotic legs), an evil lair, and a diabolical scheme. She also develops an evil laugh, which is more like a gargle.

After calming down, Robin tries to entertain himself by throwing bird-a-rangs at the ceiling in his room. Suddenly, Starfire the Terrible bursts into his room, declaring that she is ready to begin their rivalry. Robin tells her that he could never hate her, so she decides to destroy the one thing that matters to Robin the most: his year supply of hair gel, preventing him form ever having spiky hair again. This puts Robin in shock, and, shortly after, his hair falls downwards unkempt. After suffering a terrible loss, Robin decides he has no choice but to become her enemy.

Robin retreats to the living room, where Cyborg, Beast Boy, and Raven are playing a game. He tells them to prepare for the worst, as his arch-enemy is on her way. The Titans laugh, thinking there's no way Starfire could be a great villain. Suddenly, Starfire breaks in with a warning that nobody can protect them from what she is about to unleash upon the world. The other Titans are still convinced that she could never be a villain, and proceed to mock her with what they think she will do next, like drink from the milk carton or set the microwave too high. Instead Starfire says she has rigged the moon to explode, which Cyborg dismisses.

Cut to the moon covered in dynamite seconds before it explodes shocking the other Titans Starfire laughs/gargles before she really does down the milk carton, telling them that she only did it because Robin loved the moon so much. She leaves, doing her evil laugh/gargle. The outraged Titans decide that she is a much greater threat than they had ever imagined and prepare for battle.

A short time later, the Titans infiltrate Starfire's evil lair (a giant cardboard building in their backyard) in an attempt to put a halt to her villainous ways. Prepared for their arrival, the diabolical Tamaranean activates an impressive security system consisting of laser guns made of cardboard tubes, a giant robot army, and trap doors leading to piranha tanks, all of which are activated by a cardboard control panel with crayon pictures of buttons on it she manually makes the noises for.

The Titans engage in battle with the robot army, and put up a decent fight, until Cyborg, Beast Boy, and Raven are shoved into a piranha tank by one of the robots, and the top seals above them. Robin destroys the robot who just trapped his friends, but is unable to save them apparently Robin is ready to confront Starfire at last, but she unleashes her "henchman" to fight him. Robin is easily "defeated" by Silkie's puke, and falls to the floor.

Starfire declares that she has finally done it, hoping to please Robin and is going to destroy him to finish the deed. However, Robin confesses that he only wanted an arch-nemesis so he could fit in, and apologizes. Then, Robin asks Starfire for one last request. Starfire eagerly decides to grant him one last request. Robin looks his enemy into the eyes, and simply asks, "What day is it?". Surprised and confused, Starfire tells him it is Monday.

Boom! The R-Cycle bursts through the wall, and smacks Starfire in the face, leaving a huge bruise. Filled with excitement, Robin leaps onto his bike, and exclaims "MOTORCYCLE MONDAY!". Robin continues to cheer about his so-called "victory" over his arch-nemesis, who is sitting on the floor, sadly feeling her bruise. On the screen flashes the word fin, right before the episode fades to black.

Trivia

 * It is revealed that Starfire does have feelings for Robin, as she is seen standing behind him with a flower, sad, while he is kissing the moon.
 * It is revealed in this episode that the thing Robin values most in life is spiked hair.
 * In the original series episode, "Revved Up", Starfire masqueraded as a villain known as the Dr. Amazing Mumgon the Terrible. This name was a mash up of several villain names from the series, specifically Dr. Light, the Amazing Mumbo (or "Mumbo Jumbo"), and Trigon the Terrible.
 * In both series, she was accompanied by a henchman (Raven as Henchie from the original series and Silkie in this episode).
 * In the short time it took her to become a villain, Starfire created her attire and her secret lair out of cardboard behind Titans Tower, make a villain theme that plays on a boom-box, destroyed one year's supply of Robin's hair gel, her boom-box, and the moon, drank directly from the milk carton, built lasers, an army of death bots, and a pool of piranhas, to the disbelief of Cyborg, Raven and Beast Boy, and grant her main foe one last request (an old school villain gimmick), which coincidentally became her downfall.
 * As a villain, Starfire's starbolts have turned purplish-pink (at least temporarily), similar to her evil sister Blackfire in the original series and her original, comic version's starbolts.
 * This is the first time Starfire's starbolts appear like fire in Teen Titans Go!
 * It is revealed that Robin's hair gel is green.
 * It is unknown whether or not Cyborg, Beast Boy and Raven were killed by the piranhas. They might have, but this may've been for comedic effect, as they appear in the next episode.
 * In the original series episode, "Mother Mae-Eye", Robin is revealed to wear hair gel, though in a few earlier episodes, Robin's hair stays spiked up, even after going into water such as in "Wavelength."
 * As a villain, Starfire carried a boombox with her theme, which she promptly destroyed.
 * The R-Cycle from the original series finally makes an appearance.
 * Robin is shown with a Starfire poster and a calander of Starfire's schedule in his room.

Continuity

 * Presumably, Starfire may have been responsible for the deaths of Beast Boy, Cyborg and Raven. This would mark Cyborgs seventh death in the series. As well as Beast Boy's fourth death ("Dog Hand", "Ghostboy", "Parasite") and Raven's third death ("Ghostboy", "Parasite").
 * Music from "Driver's Ed" when Robin drives into the water and "Meatball Party" when Beast Boy asks Raven if he could us her magic book returns during two of Starfire's head transitions. Also, the Jeopardy- like music from "Terra-ized" returns when Beast Boy, Cyborg and Raven list lame "evil-doings" they thought Starfire would do before blowing up the moon.

Errors

 * The Titans say that Robin does not have a arch-enemy. However, Slade was Robin's arch enemy in the original series. Its possible that Slade does not exist or has not shown in this series so far.

Running Gag

 * One of Robin's hair gel containers (that didn't get blown up by Starfire's starbolt) rolls up to Starfire and Robin, who looks relieved until Starfire destroys it and levitates away smiling.
