Stewart St John is an award-winning writer, producer, director, filmmaker, composer, and multimedia creator known for building original story worlds driven by compelling characters, emotional storytelling, and music.

With a lifelong passion for animation, comics, and storytelling, Stewart began his career at Hanna-Barbera, where he was mentored by legendary co-founder Joe Barbera (creator of The Flintstones and The Jetsons). There, he wrote for Tom & Jerry Kids, contributed original songs, and co-created the short film DINO, now housed at the Museum of Television & Radio in Beverly Hills.

He later worked under Haim Saban, helping shape the early evolution of Mighty Morphin Power Rangers where he became story editor and writer —including co-architecting the iconic five-part “Green With Evil” saga that introduced the Green Ranger and helped propel the series into its next phase of global success—while gaining firsthand insight into large-scale franchise storytelling and brand building.

He went on to write for some of the most iconic children’s and family series worldwide, including V.R. Troopers, Sabrina: The Animated Series, Marvel’s The Incredible Hulk, Inspector Gadget, the Disney Channel Original Movie Seventeen Again and many more.

Stewart was also the originating writer of The Legend of Prince Valiant episode that went on to receive the prestigious Humanitas Prize for its powerful exploration of child abuse. He also received a Young Artist Award for his work on ABC’s Sabrina: The Animated Series, while Seventeen Again earned a nomination in the same category.

His work has received notable recognition across the industry. Marvel’s Stan Lee selected his episode of The Incredible Hulk as one of his “favorite five” for the series’ DVD release, while hisSabrina episode “Witch Switch” was chosen by Kellogg’s for a nationwide standalone DVD release.

A pioneer in digital storytelling, Stewart was a key creative force behind The Spot—widely recognized as the first episodic web series—helping define early interactive online narrative. He later co-created The Spot Wireless, considered the first mobile soap opera, and created, wrote, and directed California Heaven, one of the earliest scripted series produced specifically for online distribution. He went on to launch and oversee an independent digital network of original programming, helping bridge the transition from traditional television to emerging streaming platforms.

In 2016, Stewart co-founded Wonkybot Entertainment with partners Todd Fisher and Michael Plahuta, establishing a creator-driven studio focused on developing original, multi-platform intellectual property. Under Wonkybot, he has created a growing slate of franchises including Tara Tremendous, Spooky Troop, The Owlsteins, Bliss, Origins Unknown, and Dr. Epicopolis & 1102, spanning audio, animation, publishing, and film.

The Tara Tremendous franchise—originating as a hit audio series—has expanded into live stage productions, publishing, and a feature film currently in development, positioning it as a flagship property within Wonkybot’s interconnected story universe.

In 2025, Stewart launched Wonkybot’s animation division with the debut of The Swines, an original adult animated comedy series, followed by the 2026 rollout of Wonkybot Kids, a dedicated platform for family-focused animated content. Leading the children’s slate is BLISS, a musical preschool series centered on emotional growth, imagination, and kindness.

Stewart continues to develop and oversee a slate of original film, television, and animated projects, combining traditional storytelling craft with innovative production models to build scalable, creator-owned entertainment for global audiences.

A composer, songwriter, and music producer, Stewart is also a voting member of the Recording Academy (GRAMMY®), integrating original music across all of his storytelling platforms.

Across every medium—from early web and mobile storytelling to animation, film, books, and music—Stewart’s guiding philosophy remains the same: to tell human stories that entertain, inspire, and evolve with the times.
