Voltron: Defender of the Universe

Haggar and Lotor send a group of poisoned seeds to Arus which produce handsome plants - which weaken all who pick them for their beauty. Coran and the Voltron Force learn that an antidote is available through a crop of flowers on the magnetically-surrounded Planet Lyra. Allura suggests the underwater-dwelling Blue Lion could fly there since its being used to water would let it through the magnetic field, but she too sickens from a group of the flowers and Lance goes out instead. With the help of a young Lyran named Farla, he tries to get King Mac's permission to harvest some of the plants, but Lotor is waiting with him. He plans to take the plants himself and hold ARus ransom for the sake of their ruler, especially since he knows one of the Voltron Force is dying and another must get past him. Lance loses a duel to him and falls from an infamous wall into a river, but escapes to the Blue Lion, where he must somehow stop Lotor from ruining the crop except for what he'll steal so only he can heal Allura at the cost of Arus - or anyone else.

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. The Voltron Force cannot escape, and conclude that Bandor must use his arsenal to strike the comet away from Arus - though they know it means self-sacrifice.

The one who approaches Romelle after her being forced into the Pit of Skulls is a young, wild-eyed man who warns her of the approaching guards that come down to ensure she is finished, and helps her into a passageway through a cave but then vehemently bids her leave him. She is able to identify him as Sven, but the former pilot of the Blue Lion has lost his faith in himself, feeling remorse over his defeat by Haggar and his inability to aid Planet Ebb when it was attacked when he was hospitalized, and is nearly mad with grief after witnessing so many brutalities every day. Romelle tries to convince Sven to help her get off Doom and contact the Voltron Force so she can return to and defend Pollux as only she knows how, with the help of a group of slaves who are desperate for their own freedom and could be what they need to help them escape...
