Rick and Morty vs. Genocider

Rick leaves Morty at the Citadel of Ricks, and heads for Tokyo. The Citadel, under the control of Evil Morty, tell Morty that Rick is being hunted by a group called the "Genociders". They are destroying life by changing memories, with the intention that only Rick will be left at the end. However, the Genociders are really the Citadel themselves, who are hunting Rick. Meanwhile Morty travels to Tokyo to find Rick.
