Origin and Inspiration

According to an online interview, Bob Boyle took the inspiration "from a trip my wife and I made to Little Tokyo (in Los Angeles) and saw a little girl wearing a shirt that said 'Samurai in Training.' I thought that's cute, and then that a tiny samurai would be not only be funny, but hilarious!! and then went to 'what is the cutest animal and thought of a fluffy little bunny and it took off from there. Always hearing from folks in pitches that an idea didn't have enough boy appeal, or enough girl appeal, I thought why not do both. Have equal characters, or equal importance, boy and girl. Then give them that sibling rivalry." Yo was included later on during the production.

Setting and Premise

The setting is in an Asian part in Chicago. The town is a combination of Western and Asian styles, with several architects built in either a Western or Eastern fashion. The residents are monsters, humanoids, robots and animals given anthropomorphic qualities. The residents keep unusual pets like puppygriffs, a hybrid between a puppy and a griffin, as well as real animals like dogs, cats, opossums or armadillos. Magic and martial arts have been prominent since ancient times when the Night Masters were around.

Yin Yang Yo! follows the escapades of two anthropomorphic rabbit twins named Yin and Yang training under Master Yo, a grumpy old panda who is revealed to be their father. They learn the sacred art of Woo Foo, a special type of martial arts that involves might and magic. They must work together to save the world from evil villains and forces that want to destroy, corrupt, or take it over. Through all these adventures, Yin and Yang still portray typical siblings; sometimes disagreeing with each other, but still care about each other and working together when needed.

During the first season, the primary goal was to defeat the Night Master, a powerful enemy. Through the course of 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.
