Yin Yang Yo! is an American 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 centers on two anthropomorphic twin rabbits named Yin and Yang, and their sensei-like panda figure named Yo, a master of the fictional mystical martial art Woo Foo.

The show's staff consisted of many writers and animators associated with The Fairly OddParents, 6teen, My Life as a Teenage Robot, Invader Zim, Clone High, Wow! Wow! Wubbzy! and Danny Phantom. Head writer Steve Marmel took inspiration from various anime like FLCL and anime-influenced shows such as Teen Titans and Avatar: The Last Airbender.

Premise The show is about two 11-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, corrupting or dominating 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 for 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 Night Master, Eradicus.

Setting 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. The episode "Yin Yang You!" reveals that the series takes place in another dimension.

Villains The Night Master (voiced by David Hemblen) is an ancient sorcerer who previously eradicated all of the Woo Foo knights except for Master Yo. The Sensei managed to turn Night Master's army to stone and sent him into hiding for a hundred years until he tricked Yin and Yang into using Woo Foo in order to free his army. He is highly intelligent, though his plans typically fail because of the stupidity of his minions and his own ego. The episode "The Pecking Order" reveals the Night Master to be a title previously held by Eradicus and an unnamed cobra-like woman.

Eradicus (voiced by Jonathan Wilson) is a griffin and the first Night Master. He was killed years prior under unknown circumstances.

Her appearance and mannerisms are a parody of Japanese culture. Mirrors (voiced by Jamie Watson) is Smoke's brother and rival. His appearance and mannerisms are a parody of Japanese culture, and he and Smoke's names are a play on the metaphor "smoke and mirrors".

After he lost his physical form, he was found by the Night Master who built him a robotic suit to absorb Woo Foo so he could become real.

Saranoia (voiced by Linda Ballantyne) is a sorceress and mistress of disguise. She had a difficult childhood with her father and her lazy brother Mark, which led her to develop feminist views and values. Saranoia was condemned to an insane asylum from "The Truth Hurts" to "A Bad Case of the Buglies". Yin and Yang filed a restraining order on her. At this point, she has given up evil and is the spokesperson for Repulsix. G.P. (voiced by David Berni) is Saranoia's gnome-like assistant. He later changes his name to Fr-Ped, an acronym for "Frighteningly Really Powerful Enraged Doombringer" (pronounced Fred).
