Blackout is the thirteenth episode of the Second Season of Voltron: Legendary Defender.
The Paladins fight to systematically destroy the base to prevent Zarkon's return. As Zarkon himself goes to battle Voltron, Haggar and her Druids go to protect their emperor as he readies his armor, which untested could kill him as well as Voltron. Before Zarkon can do anything, Haggar uses her dark magic to forcefully remove the Quintessence from Voltron, but is overloaded by the purity of Voltron. While the Lions are unresponsive, their Paladins still live, but Zarkon arrives in a Robeast in his image. Allura uses whatever power she can to stall Zarkon to allow the Paladins to recover and battle Zarkon's Ro-beast. Allura, Kolivan and Antok go to battle Haggar to keep her from using her witchcraft from delaying Voltron. As their battles rage, Zarkon splits Voltron back to the individual Lions with Shiro unconcious; Allura and Kolivan triumph in their fights, while Antok perishes at the hand of Haggar and another Druid. Shiro awakens to see his team being beaten, and the Bayard access port in his Black Lion activates, activating its Transcendent Wings to phase through Zarkon's Robeast and reclaim the original Black Bayard. As their fight continues, Haggar is revealed to be Altean, and Allura learns she has the power to command Quintessence, which she uses to defeat Haggar and Kolivan avenges Antok. Forming Voltron, the Paladins fight with new strength and Shiro uses his Bayard to supercharge the Voltron Sword and destroy Zarkon's Robeast armor.
After the battle, back in the Castle hangar, the Paladins discover that Shiro has vanished from the Black Lion leaving his Bayard behind. On Zarkon's ship, Zarkon is on life support, prompting Haggar to summon Prince Lotor.
