After acquiring the teludav from Olkari, the team prepares to launch the operation to defeat Zarkon and bring peace to the universe. When the Marmorans haven't heard from Thace, they urge a delay in action, while Allura argues they continue. Keith plans to infiltrate the main ship of the Galra Fleet, but before leaving Allura stops him to explain that since waking up she views the Paladins as her new family and his being part Galra made her unsure. Following Thace's capture, the Druids interrogate him, and allow him to escape. Haggar helps Zarkon find the Black Lion, Zarkon's fleet arrives, Shiro distracts while Keith sneaks aboard. Despite that the battle is a trap, Zarkon is too engrossed in reclaiming the black Lion. Since the Druids rewrote the shield codes, their plan adapts to turn the core room into a bomb and cripple Zarkon's ship. When the Druids are sent after Thace while Zarkon has a rematch with Team Voltron. Thace sacrifices himself to cause the power core to overload and explode, just as the cloak teludav loses its cloak, and Zarkon's ship loses power. As Zarkon's ship is wormholed to another reach of the universe far away, the Paladins pursue to finally end Zarkon.
For millennia, the evil Galra Empire has plagued the universe by conquering planets and destroying their inhabitants. The only known threat to the empire's power and plans, is the legendary "Defender of the Universe" Voltron, a 100 meter tall robot warrior composed of five lion mechas whose whereabouts are presumed to be unknown. The Galra Empire's path of conquest and search for Voltron has led them to Earth's solar system. A group of space pilots-Shiro, Keith, Lance, Pidge, and Hunk-discover the blue lion and immediately get swept up into the Galran War. They meet Princess Allura, become the next Paladins, and reunite the five lions to form Voltron and free the universe from the Galra Empire.
**NOTE: Even though Netflix releases all episodes of Voltron: Legendary Defender on one day, they are portrayed on the TV Calendar as airing one episode a day, for ease of visualisation.
