Family Guy spin-off Stewie has announced its voice cast ahead of its planned 2027–28 television-season debut. The series will follow Stewie Griffin’s adventures after he is forced into a new, poorly regarded kindergarten, using his inventions to turn ordinary school days into time- and space-travelling escapades.

Seth MacFarlane will voice both Stewie and classmate Bean, while Kenan Thompson plays Royal, a sceptical fellow pupil. Mike Henry will voice BJ, Melissa O’Neil will play Stewie’s crush Wanda, and Aaron Lee will voice Skunk, the class’s 100-year-old turtle; Brian is expected to appear recurrently. The show already has a two-season order, with MacFarlane as co-creator and executive producer and long-serving Family Guy writer Kirker Butler as showrunner.
