It Takes Real Lions
As Lotor prepares to for another attack on Arus, Allura is forced to work harder on the things she'll be expected to do as a ruler instead of spending leisure-time with the friends she trains with.

This nearly results in their capture after they find a massive shooting-machine. He is trusted by Lotor for his attempt to see the gun completed in a desperate hope that he will free his people. When the two approach Haran, he reveals that he blames Voltron for their enslavement, since Moura aided them in defense against Zarkon but Voltron was abroad and unable to intervene when Moura was captured. They vainly plead to have him support Voltron in order to see Zarkon's rule overthrown, and are forced to regroup to fight the weapon as well as the powerful Centipede Express Zarkon arrives in.
22 min
The Invisible Robeast
The gist of this one is implied pretty well by the title - Zarkon and Co. send an invisible Robeast to Arus to take care of the Voltron Force. Coming back in a carriage after a day of picking fruit, Allura, Nanny, Lance and Pidge and some space mice are caught offguard when the invisible Robeast attacks. It overturns their carriage into a nearby lake - luckily, all are able to escape a watery fate. But before Allura can climb out of the lake, the Robeast picks her up and carries her away. After a few well placed laser blasts from Pidge's pistol, the Robeast drops Allura. However, it's not done with them. Hiding near a bluff, they're shocked to find a bolder the Robeast threw barreling toward them. Fortunately, the others at the Castle caught an inkling of what was going on and so the boulder harmlessly ends its journey on the back of Black Lion.
22 min
The Green Medusa
Lotor goes to the fume-covered Planet Medusa to arouse and take one of its sleeping inhabitants to fight for him. It turns out to be a monster who can attack with snakes as hair and turn things to stone. The Voltron Force are called away from trying to arrange homes for those orphaned by Zarkon's raid against Arus to fight it. Pidge is forced to eject his struck Green Lion, knocked unconscious, and taken underground by the beast. While the others wonder whether they'll see him again, he is horrified to recover near the creature, but finds the being, Anga, is kind to him. Haggar is determined to turn it evil so it will no longer side against its captors and with their enemy, while Lotor takes advantage of the divided protectors of Arus by sending another menace out. It is up to Pidge to see that no one falls under their power.

Treasure of Planet Tyrus
To celebrate his birthday, Lotor takes a trip to planet Tyrus.

The Captive Comet
Haggar locates and takes control of the Omega Comet, a legendary black-hole-like structure which crushes and destroys anything in its path, and sends it for Arus. Though Voltron redirected it once after a decade of trying, the Voltron Force are forced to race against time to move it themselves after they get Romelle's warning. Seeing Allura's cousin's loyalty to them, Lotor mentions that a certain control-function will help them in front of Romelle, and she relays the information to them. But it was a trap Lotor had her lure them into, and they crash-land and are stranded upon the comet without power. The Galaxy Alliance can send no reinforcements thanks to Zarkon's fighting. But Bandor goes against orders to stop guarding the power-supply he was posted in front of to repay his comrades.
