'Rick and Morty' Season 6 Premiere Date: What to Know

Adult Swim has announced that Rick and Morty Season 6 will premiere on Sunday, Sept. 4. The announcement came with little buildup for fanfare, and just one new teaser image. It shows the two titular characters wearing smug grins and crop tops with exaggerated muscles visible beneath.

Rick and Morty Season 6 will return to the series' usual time slot at 11 p.m. ET on Sunday nights. It comes in the midst of a few other huge announcements from the Rick and Morty team, including a spinoff series that will air on Adult Swim. The two co-creators also have other projects in production — Justin Roiland's Solar Opposites and Dan Harmon's Krapopolis — along with other tangentially-related projects like Star Trek: Lower Decks. For die-hard fans, the return of the main series is a welcome surprise.

The logline for the new season reads: "It's season six and Rick and Morty are back! Pick up where we left them, worse for wear and down on their luck. Will they manage to bounce back for more adventures? Or will they get swept up in an ocean of piss! Who knows?! Piss! Family! Intrigue! A bunch of dinosaurs! More piss! Another can't miss season of your favorite show."

Typically, Rick and Morty resists serialization and canonical storytelling, but fans may recall that Season 5 seemed to end on an important cliffhanger. The show brought back the mysterious "Evil Morty" and revealed that his plan has always been to destroy or escape the "Central Finite Curve" – a multiversal structure containing all the timelines that met the preferences of the Citadel of Ricks. The finale ended with Evil Morty escaping into a portal that was yellow rather than green, and with our Rick and Morty flying away on a ship full of refugee Mortys.

Whether the show will pick up where it left off or flippantly ignore this cataclysm for a while remains to be seen. In all likelihood, Season 6 will feature a mixture of episodic tales and continuous threads. The show has developed a pattern of tackling "canon" stories once every other season, so Season 6 could be light on things like Evil Morty while Season 7 could bring them back.

Adult Swim president Michael Ouweleen issued a statement along with Wednesday's big announcement. It read: "It's hard to overstate the impact of Rick and Morty. More than a hit show, it is truly a global phenomenon. As we prepare to launch this soon-to-be iconic season, we will be giving fans a unique way to be part of the fun – so keep your eyes peeled."

Rick and Morty Season 6 premieres on Sunday, Sept. 4 at 11 p.m. ET on Adult Swim. The five previous seasons are streaming now on HBO Max and Hulu.
