Final Space Season 4 Release Date, Cast And Plot - What We Know So Far

Since its debut on TBS in 2018, Olan Rogers and David Sacks' animated series "Final Space" has provided plenty of laughs along with tension throughout its completed two seasons, with the second switching platforms to Cartoon Network's night-shift channel, Adult Swim. With its third season on the air each Saturday until its two-part season finale in June, fans are already looking forward to what might be next for the series, including the fates of our protagonists Gary Goodspeed and Mooncake (both voiced by Rogers himself) and the mystery of the titular Final Space.

The series has acquired a passionate and dedicated fanbase, in large part thanks to its excellent animation and blend of comedy with more serious moments, as well as a truly stellar voice cast including the talents of David Tennant, Tom Kenny, Conan O'Brien, Ron Perlman, and more.

Although there's still a lot we don't know about the future of the series, here is everything we do know about Season 4 of "Final Space," including any information or educated guesses we have about its release date, cast, and plot.

We haven't had final word on whether there'll be a fourth season, but the announcement might be imminent

As of now, we don't have any official word on whether the third season of "Final Space" will be the final one, but if we go by past precedent, we hopefully shouldn't have long to find out. After the first season's finale finished airing, we immediately got confirmation of a second season the same day, and we only had to wait a week after the show's second season finale to get confirmation for a third season. If we go by the same trend, we'll hopefully get confirmation of a fourth season not too long after the third season wraps up on June 6, hopefully that same day.

As far as when we might expect to sit down and actually watch the fourth season, we can look to precedent again to get a general idea. There was just over a year's wait between the first and second seasons, with the Season 1 finale airing May 7, 2018, and the Season 2 premiere airing June 24, 2019. The wait for the third season was a little longer: The second season wrapped up on September 23, 2019, but we didn't see Season 3 until March 20, 2021, making the wait just under 18 months. However, we can likely blame COVID-19 for the slightly longer delay, hopefully meaning that we'll see a fourth season sometime in the first half of 2022.

Who might be in the cast for Season 4 of Final Space?

Without an official confirmation, we certainly don't have an official cast list, but we can again make some educated guesses based on what information we have.

Due to the series messing with multiple timelines, not even death is a final confirmation that we won't see any particular character again, so no matter what happens in Season 3, be prepared for anything and anyone to return for Season 4.

We can safely assume that series protagonist Gary Goodspeed would return with Olan Rogers in the lead role, as well as voicing a number of supporting characters. Other mainstays we've heard voice multiple characters include Tom Kenny (HUE, SAMES), Fred Armisen (KVN, Eduardo), Tika Sumpter (Quinn Ergon, Nightfall) and Steven Yeun (Little Cato, Mr. Graven) voicing a collective total of 48 characters, although IMDb's "additional voices" suggest the actual number may be much higher when including incidental characters.

As far as other cast members we hope will return, there's Ashly Burch in the role of Ash Graven, Ron Funches as Fox, Claudia Black as Sheryl Goodspeed, Vanessa Marshall as Invictus, and, of course, David Tennant as the villainous Lord Commander.

What can we expect for Final Space Season 4's plot?

With the third season still running, it's difficult to fully predict what we might see for Season 4 yet, but as always, we have some ideas.

Season 3 has really leaned into the darker themes of the show, with the recurring tagline and theme being "survival" as its characters find themselves trapped within Final Space itself. Given that some characters will survive this season, we might expect the next one to play off these themes with more empowered characters, using the knowledge they now have of Final Space and the universe in order to avenge any fallen heroes and go after Invictus. The Season 3 finale also teases that "Long-held secrets are revealed that will change the Team Squad forever," so whatever these changes are, we'll have to contend with them if and when Season 4 rolls around.

New episodes of "Final Space" air Saturdays at 10:30 p.m. ET on Adult Swim, with the first two seasons available to stream on HBO Max in the United States.
