This Is The End, part 1 S01 E12

In Cyberland, everyone is summoned before Zorak because the treacherous sorcerer has succeeded: he has captured Floyd, Quix, King Bing and Astrella and has tasked Zeist with going to Earth to eliminate the four Cyberkidz and take their gloves. While Zeist is on Earth, his brother Levuka, with whom he has never gotten along, will replace him. Zeist completes the task and it seems like the end has come for our heroes.
