Thief in the Night

The traitor Octane and the city-bot Trypticon scheme with a corrupt dictator to seize power.

Rodimus Prime, Grimlock, Perceptor, and the Aerialbots are reviewing the footage of Metroplex's battle with Trypticon. Grimlock declares that he wants to see the "good part", where Metroplex destroyed Trypticon, but Teletraan II states that Trypticon survived the encounter. Broadside and Seaspray travel to where Trypticon landed in the ocean, and learn that he walked underwater to avoid being caught.

Meanwhile, the Triple Changer Octane is nursing Trypticon back to health, using energon made from the oil of Carbombya. Octane hopes that with Trypticon to back him up, he can overthrow Galvatron and become leader of the Decepticons. However, Abdul Fakkadi, the leader of the desert nation, is unhappy with Trypticon's constant consumption of oil. Fakkadi demands that the two Decepticons leave, or he will call the Autobots. Octane offers to bring Fakkadi gold in exchange for being able to stay, but Fakkadi declares that it would take all the gold of the United States to allow them to stay. The simple answer? Octane has Trypticon steal Fort Knox.

Pacified, Fakkadi agrees to allow the Decepticons to remain in Carbombya until the next crescent moon, and Trypticon is put under strict ration of one thousand barrels a day. Octane declares that Trypticon will starve, and negotiates a new plan: give Fakkadi a new palace, and he will let them stay and have more oil. To make Fakkadi "more happy", Trypticon steals the Taj Mahal.

While the Autobots investigate the disappearance of Fort Knox ('cause that's something that directly involves the Autobots), Grimlock finds energon cubes which he says "smell different". As Perceptor begins analyzing the energon, Grimlock also smells dinosaur transform static, and fears one of his own Dinobots may have been involved. Metroplex decides to interrogate all the Dinobots.

At Carbombya, Fakkadi is pleased, declaring that with enough monuments, they will soon have a thriving tourist attraction. However, Galvatron has been tracking down Trypticon. He declares Octane a traitor, saying he stole Trypticon from Dinobot Island. Thinking fast, Octane claims that he brought Trypticon to Carbombya to help him get better, with a more powerful form of energon, and tosses Galvatron a cube. As Trypticon says nothing to contradict the story, Galvatron takes a swig, and finds that it is stronger.

Meanwhile, Six-Gun and Scamper are interrogating the Dinobots, as well as Sky Lynx, under the watchful eye of Metroplex. Sky Lynx angrily objects to being called a Dinobot, and refuses to participate. Perceptor runs in declaring that the energon Grimlock found was made via a Decepticon formula, with Carbombyan oil. Perceptor believes that Trypticon is responsible for the thefts. Broadside takes the Aerialbots to investigate, and spots the two stolen buildings. However, Trypticon surfaces, carrying the Eiffel Tower. Galvatron and Octane are explaining to Fakkadi that the Decepticons will supply Carbombya with more buildings, such as the Kremlin, while they take over the oil fields. However, Trypticon spots the Aerialbots, and converts to battle mode, forcing the Aerialbots to retreat.

Having learned that Trypticon intends to take the Kremlin, the Autobots head to Moscow, but Metroplex is late. In the night fog, Trypticon arrives and steals the Kremlin, but Metroplex interrupts him. Metroplex takes back the Kremlin while Trypticon flees, and the Soviet government accuses the Autobots of the theft, as does India. Grimlock laments the Autobots' sad fate.

At Carbombya, Fakkadi is recording a message to send to the Autobots, authorizing them to invade Carbombya and attack the Decepticons. Galvatron, however, simply locks up the dictator. Rodimus, the Dinobots, the Aerialbots, Metroplex, and Broadside arrive to fight off the Decepticons, and Metroplex throws Trypticon into the ocean (again). Without Trypticon to even the odds, Galvatron orders the 'Cons to retreat. Metroplex returns the monuments, clearing the Autobots' name. Rodimus asks Fakkadi to never ally with the Decepticons again. Fakkadi promises the Autobot leader that he will not, swearing by the livestock of his various family members.
