Sinopsis:

Picking up where season four of Rick and Morty left off, see the outrageous Balthromaw and his dragons embroil in a tantalising adventure where only Morty (and Grampa Leonard) can save them. And when none other than Fascist Teddy bear Rick shows up to ruin Rick's plan for the perfect vacation, no one is safe![2] It's a world-building-bake off...at UNIVERSAL SCALE! As millennia pass in the pocket universe, Rick and Fascist Teddy Bear Rick engage one another in a scientific wager to create (different forms of) utopia, while Morty and Grandpa Leonard engage in a wild adventure to save all dragon-kind.[4] One universe goes to war...the other goes shopping? It's Pocket World War I, as each Rick is one-upping another's armies in an overly petty game of cat and mouse. The ones who suffer the most from the created citizens of each Rick's civilisation, who are afraid of upsetting the Ricks. At least, most of them are... Meanwhile, Morty, Leonard, and the dragons are on the hunt for the mythical "Dragon Toys".[5] As Rick and Fascist Teddy Bear Rick reluctantly unite against their creations, Leonard gets a very special title from the dragons.[
