Proving that one is never too young to headline their own series, Fox and Hulu have given a two-season order to Stewie, a spinoff of global juggernaut Family Guy centered on the Griffins’ evil genius toddler son. The new animated comedy, which will follow Stewie in preschool and explore time and space travel, comes from Family Guy creator Seth MacFarlane and 20th Television Animation. It is targeted to premiere on Fox during the 2027-28 season, streaming next day on Hulu and internationally on Disney+.
Stewie, whose concept art you can see above, will join Fox’s slate of long-running 20th TV Animation series: Family Guy and American Dad! — both from MacFarlane — as well as The Simpsons and Bob’s Burgers, which all received four-season renewals in 2025 as part of an unprecedented 4×4 mega deal. The two-year pickup for Stewie will synch it up with the rest; the deals for all five animated shows are now running through 2029, which is also when Fox’s current $1.5B in-season streaming pact with 20th TV’s Disney sibling Hulu expires.
According the sources, the deal for Stewie is structured differently than the others, with Fox and Hulu sharing the cost, making this a joint commission by the network and the platform.
The episode count for Stewie has not been revealed. I hear it’s slightly less than the 15 episodes per season the legacy 20th Animation series are producing under the current Fox deal.
MacFarlane, who voices Stewie on Family Guy, will do the same on the eponymous spinoff series, which he created with long-time Family Guy writer-producer Kirker Butler.
In the offshoot, after getting the boot from his old preschool, Stewie is forced to enroll in a new one that’s not exactly top-of-the-line. It’s attended by a handful of kids he doesn’t know, and a 75-year-old class turtle with a half-cocked theory on just about every subject. Stewie’s miserable, the other kids are miserable, and even the turtle is miserable… until Stewie begins rolling out his trusty array of devices to take them anywhere in space and time, turning every boring day at school into an insane and surreal adventure.
It is still early days but I hear the spinoff will have its own world at a new school with new characters and will not impact Stewie on Family Guy where the eloquent toddler with upper-class British accent currently attends Quahog Preschool.
As the concept art for Stewie suggests, it will feature references to the mothership series. For instance, the hyper intelligent and mischievous little boy is seen holding his favorite teddy bear Rupert and standing on the return pad of the time machine he built on Family Guy, which he has used a number of times, most notably to travel back in time and save his beloved dog and companion Brian from being killed by a car. Brian is expected to make appearances on the offshoot.
Over the course of Family Guy’s 24-year run to date, Stewie has evolved (and mellowed), with his priorities shifting from his sole focus on killing his mom Lois and achieving world domination to his friendship and adventures with Brian as well as creating more complex scientific inventions, including multiverse-traversing devices.
MacFarlane executive produces Stewie for Fuzzy Door alongside Butler, who serves as showrunner, and Kara Vallow. 20th Animation is the studio.
