Yin Yang Yo! is a Flash animated television series created by Bob Boyle for Jetix. Produced by Walt Disney Television Animation as the third Jetix original series, it first aired on August 26, 2006, as a sneak peek and premiered on September 4, 2006, in the United States. The show debuted on Jetix in the United Kingdom on February 5, 2007, after a sneak peek preview on January 27, 2007, while making its Canadian television premiere on Family Channel on March 25, 2007. The series is supplied with writers and animators' staff associated with The Fairly OddParents, 6teen, Clone High, Wow! Wow! Wubbzy! and Danny Phantom.[1][2] Head writer Steve Marmel, an anime fan,[2] took an inspiration from various anime like FLCL and anime-influenced shows such as Teen Titans.[2] The series centers on two anthropomorphic twin rabbits named Yin and Yang, and their sensei-like panda figure named Yo, a master of fictional mystical martial arts called Woo Foo.

During 2007, this show was nominated for British Academy Children's Award by the BAFTA in the International category, but lost to Nickelodeon's SpongeBob SquarePants.[3]


The show is about two 12-year-old rabbits named Yin and Yang who train under Master Yo, a grumpy old panda. They learn the sacred art of Woo Foo, a special type of martial arts that involves both might and magic. They must work together to defeat evil villains and forces motivated on destroying, corrupt or dominate society.

During the first season, the primary goal was to defeat the Night Master, a powerful enemy. During the second season, there are three primary storylines. The first one sees Yin and Yang trying to prevent other villains from being crowned the new Night Master. The second is Yang's own quest to find powerful mystic artifacts by some later-revealed-to-be villains: four evil heads who he thinks are the masters of Woo Foo. The third sees Yin and Yang against the original and reborn Night Master Eradicus — ultimately trying to build a Woo Foo army to fight against his army.


The setting is in a town where its buildings have an Asian style. The residents are monsters, humanoids, robots and animals with human-like qualities and behaviors. The residents keep unusual pets like puppygriffs (creatures that are half puppy and half eagle) and two-ni-corns (a race of two-horned unicorns), as well as real animals like dogs, cats, opossums or armadillos. Magic and martial arts still exist since ancient times when the Night Masters were around. It is revealed in "Yin Yang You!", that the series takes place in another dimension.[citation needed]

The series was created by Bob Boyle,[2] an animator and storyboard artist previously working on Nickelodeon projects such as The Fairly OddParents and Danny Phantom. Influenced by his frequent trips to Little Tokyo, Los Angeles, Boyle developed the pilot for the series when his then-previous series Wow! Wow! Wubbzy! was in production.[12] Once the series got the green-light, Boyle initially worked simultaneously on development for the first season of both shows.[12] Steve Marmel, a stand-up comedian and also a writer for The Fairly OddParents and Danny Phantom, who has known Boyle for years, was offered a long-term contract from Disney/Jetix to participate on the project upon request by Boyle, who needed assistance on producing the show due to scheduling conflicts. Marmel, who would later create Sonny with a Chance and So Random!, drew influence from anime shows such as Gainax-produced FLCL, putting American anime-influenced animated shows like Teen Titans and Samurai Jack in the mix, using it as driving force to deliver comedy.[2] Although a show directed at general audiences, especially children over 6 years old,[13] with its mildly risqué innuendos it also targets adults as well.[2][14]

"They asked if I wanted to work on Bob's show because it was their first comedy. It was just a match. I'm working with a friend and I'm working with a genre that I love, anime. I don't think anybody's ever done a flat-out tweak on it for comedy purposes. There have been some tongue-in-cheek moments, but nobody's ever said 'We're going to play with this and make it our own," you know? Do to anime what Seinfeld did to comedy."

— Steve Marmel[2]

John Fountain[15] (who participated in Fairly OddParents, My Life as a Teenage Robot) was brought on board as a series director for the initial first season when his work for My Life as a Teenage Robot was concluding.[16] Fountain worked closely with Marmel and Boyle on developing the lore of the show, and occasionally assisted in storyboarding the first episode, writing and co-voice directing with Marmel. Eric Trueheart (Invader Zim) also assisted in writing scripts and co-voice directing with Marmel during the second season.

For cost efficiency due to the small budget and crew the series had, the majority of pre-production for the series—including animation, voice recording, and storyboarding—was done in Toronto.[12] The majority of the character design direction was done by Mark Thornton and Todd Kaufman (co-creators of Grojband and Looped, and character designers for Total Drama).[17] The animation for the show was provided by Elliott Animation, a Canadian animation studio previously working on the Teletoon's 6teen. A different group of animators, who work on revisions and interstitials,[18] come from the Disney campus of Burbank in California, United States[2][15] and Frederator Studios, producer of many Nickelodeon titles.[1] As it's an American co-production by Disney, many actors that worked in Disney productions such as Kyle Massey, Jason Earles and Mitchel Musso guest starred as voice actors in the series.[18]

The music for the show was provided by Michael Tavera, who also created music for Time Squad and ¡Mucha Lucha!, while the theme song was written by Bob Boyle and Guy Moon (composer for Fairly OddParents and Danny Phantom), produced by Moon and performed by Kyle Massey. Many episodes of Yin Yang Yo! were directed by Fountain, Mark Ackland (a director of Clone High), Ted Collyer (also director of Clone High), and Chad Hicks (also director of Total Drama, and storyboard artist for Courage the Cowardly Dog). At the same time, the main established writing force was Steve Marmel (also executive producer) with the help of Trueheart, Aydrea ten Bosch (ChalkZone), Sib Ventress (Danny Phantom). Chris Romano and Eric Falconer, responsible for Spike's Blue Mountain State, and production of How I Met Your Mother and The Sarah Silverman Program, also participated on the writing of various episodes. Staff writers Evan Gore & Heather Lombard who penned Futurama's episode "Fear of a Bot Planet" (1ACV05) and The Adventures of Jimmy Neutron, Boy Genius's episodes "Krunch Time" and "Brobot", lately dedicated their work for Lilo & Stitch: The Series, participated in the creative process of Yin Yang Yo! as well. As the series went on, Bart Jennett (Recess) became a producer and writer on the series, with many other freelance writers joining like Danielle Koenig and Rob Hummel (Invader Zim), Dave Newman and Joe Liss (Drawn Together and SpongeBob SquarePants), Amy Wolfram (Teen Titans and Xiaolin Showdown), Scott Sonneborn (Beavis and Butt-Head and Undergrads), and even former creators like Phil Walsh (Teamo Supremo) and Van Partible (Johnny Bravo).



The debut of the pilot episode on Toon Disney's Jetix block was its "most-watched original animated series premiere ever".[19] The series continued to garner high ratings on the block afterwards, tying for first place on average.[4]

In Europe, Yin Yang Yo! was the third-most popular Jetix original series for third-party sales as of fiscal year 2007, when the first season was delivered. Yin Yang Yo! and the major Jetix Europe originals ranked "as one of the top two shows in their timeslots in all of the markets in which they aired."[20]


Common Sense Media had a mixed opinion of the show, giving it a score of 3/5.[21] The pilot was poorly received by The New York Times.[22]
