Yang
Voiced by: Scott McCord

A blue, male rabbit and the twin brother of Yin. He mostly uses the Martial Arts side of Woo Foo, but he can also use the Mystic side of Woo Foo. Yang is a cuckoo, lucky, courageous character, and has a liking for clowns. Despite not usually showing it, he really cares about his sister and Master Yo's well-being. He enjoys fighting, and likes hitting stuff.

    Yin 
Yin
Voiced by: Stephanie Morgenstern

A pink, female rabbit and the twin sister of Yang. She mostly uses with the Mystic side of Woo Foo, but she is also skilled in Martial Arts. Yin is often described as intelligent, cute, girly, and sassy, but she is often quite stubborn and shows signs of being a "neat freak". Yin generally has a good sense of right and wrong, and will often do the right thing.

    Master Yo 
Master Yo
Voiced by: Martin Roach

Teacher of Yin and Yang. Yo is a grumpy old panda whose age is unknown (but he missed his 117th high school reunion). Yo has great sage wisdom and is a master in the Woo Foo arts. Master Yo mentors Yin and Yang in the Woo Foo way to save the world, but it wasn't his choice. The spirits of past Woo Foo warriors stopped him from watching a movie called Who Stole the Cookie until he decided to do it. He's able to use both might and magic and has moves that Yin and Yang have no clue about.

Allies

    Lina 
Lina
Voiced by: Novie Edwards

An aqua-green female dog, Lina is Yang's girlfriend (after "Gone-A-Fowl") and Yin's best friend. She is a nice, yet short-tempered girl who lives on a farm with her father. She was first introduced in "Beetlemania", when Yang pretended to be a Woo Foo Warrior in order to impress her, but his plan backfired after he had to fight a giant steel beetle; eventually, Yin was able to get Yang to tell the truth. Lina is often unafraid to state her opinion and even talks back to her father. She was trained by Yin and Yang to use Woo Foo and is the second-in-command of the Woo Foo army Yin and Yang gathered together.

    Roger Jr. 
Roger Jr.
Voiced by: Damon Papadopoulos

Logically the son of Yin and Yang's part-time enemy, Roger the Skelewog. At first, Roger Jr. was a bully to Yin and Yang, having mock fights with Yang and teasing him and Yin, but, during "Woofoogeddon", it was revealed he longed to be Yang's best friend. Roger Jr., being a monster, has displayed super strength, such as when he easily took out a whole group of the Night Master's soldiers just by running by them with his arms. He is also a member of the Woo Foo army Yin and Yang gathered together.

    Dave 
Dave
Voiced by: Dwayne Hill

A magical talking tree stump, Dave is a low-life and is considered pathetic by his friends. Many times, Dave is often caught in the crossfire of battles or hurt in some way by friend and/or foe. He is also whiny, talks nonstop about his family of trees, and is never noticed. As discovered in Stuck, Dave has the ability to communicate with and manipulate nonsentient plants. This apparently surpasses that of the other characters. He is now a member of Yin and Yang's Woo Foo army.

    Coop 
Coop
Voiced by: Dwayne Hill

A nerdy chicken who appears to be scared of any threats and has a huge crush on Yin but because she never returned any of his feelings, Coop joined the Night Master in exchange for the promise to have Yin when the world was taken over. He is a minor villain and he is seen with some of the other villains in the Yin, Yang, Yo intro in season 1. Coop gave the impression of incompetence, but in reality, he had powers and abilities rivaling Yin and Yang's; in the end, Coop couldn't bring himself to go through with the Night Master's plans and held him in place so Yin and Yang could destroy him. Eventually, he returns and ends up overwhelmed by the power of the Night Master, temporarily becoming evil before snapping to normal and going off to train and gain control. Upon doing so, he joins the Woo Foo army.

    Jobeaux 
Jobeaux
Voiced by: Bill Engvall

A Redneckistanian practicing Woo Foo, while being disliked by his teachers, Yin and Yang, as a stupid, smelly hick; however, when he finally gets the time to clean himself up, he reveals himself to be a smart, well-groomed young man. After defeating the Chung Pow Kitties, Jobeaux reveals his knowledge of Yin and Yang's disrespect and returns home to marry and live in a castle of diamond-encrusted grits (which Yin was fantasizing about before they met). He has a pet armadillo named Fuzzy Thunder that hides in his mouth, giving him a hick accent.

    The Boogeyman 
The Boogeyman

The Boogie Man is a disco-loving green monster that helps Yin and Yang defeat Pondscüm, Zarnot, Fastidious and Mastermind in "Roboticus Maximus". When the two rabbits were looking for a sidekick to boss around, they chose him. Eventually, they put him in charge over them which lead them to a victory. He became part of the Woo-Foo army they gathered.

Villains

    The Night Master 
The Night Master
Voiced by: David Hemblen

Billed as a "Dark Overlord in an Evil Class All By Himself", the Night Master is a very powerful and dangerous foe who was responsible for the near extinction of Woo Foo by eliminating 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. The Night Master appears to be a demonic sorcerer bat (as such, he hates light) of some description and has a liking for Gothic, ostentatious outfits.

    Carl, the Evil Cockroach Wizard 
Carl, the Evil Cockroach Wizard
Voiced by: Jamie Watson

Carl, the Evil Cockroach Wizard (who tends to shout out his name as much as possible and always wants to be called Carl the Evil Cockroach Wizard), continuously schemes to defeat Yin, Yang, Master Yo and the power of the Woo Foo with his insecure genius. He also lives with his overbearing mother Edna, who is a dragon (it makes no sense as to how they are all related). Carl is always trying to find a way to impress his mother and out-do his brother Herman. Despite his desire to win his mother's love, Carl is resentful and has talked back (usually under his breath), made her cry, and even put a spell on her.

    Eradicus 
Eradicus
Voiced by: Jonathan Wilson

A mighty Gryphon who is bent on destroying Woo Foo. As revealed in "Welcome To The Dark Tomorrow", he is in fact the first and original Night Master. After his demise (of unknown cause), other beings of darkness took on the mantle of evil he left behind including an unknown snake lady and the bat-creature Yin and Yang faced in season 1. His deceased minions posed as the ghosts of the Woo Foo Elders to manipulate Yang into collecting the items of power needed to revive him. Tricking Yang into throwing the items into the Night Master's fireplace at the stroke of midnight, Eradicus was instantly resurrected.

    Ella Mental

Voiced by: David Berni

    Ultimoose 
Ultimoose
Voiced by: Tony Daniels

Ultimoose is the ultimate Night Master lackey: tough as nails, a master at Moose fighting, and really, really dumb, despite his shortness and strong antlers. He seems to offer work under the Night Master but is merely a dim-witted pawn.

    Yuck 
Yuck
Voiced by: Scott McCord

Yuck, a turquoise-green rabbit with terrible hygiene, is an entity formed from Yin's obsession with control and Yang's aggression. As a disgusting, mutant rabbit, Yuck wants more than anything in the world to be the greatest, most powerful Woo Foo Knight of all time.

  • All Your Powers Combined: He has all of Yin and Yang's abilities

  • Heel-Face Revolving Door: Also in "Upstanding Yuck" he becomes a good guy by having a group of hooded figures beat goodness into him. Yin and Yang don't trust him of course and follow him around, ambushing him whenever his words sound like a threat. They're proven wrong in the end, realizing too late that Yuck was good all along and that their actions have only turned him back to his old ways.
  • Hermaphrodite: Though he is addressed using male pronouns, "Yin Yang Yuck!" shows him coming out of a bathroom labeled with a question mark. Then "Personality Problem" reveals that he actually does have a male and female aspect of his personality.
  • Jerk Ass

  • Vocal Evolution: His voice starts off as more nasally in the first season and sounds more raspy in "Voyage to The Center of Yo". In the second season, he has his official voice which is deeper and slightly raspy.

Deeply sexist and obsessed with female rights, she is determined to free Yin from studying Woo Foo and take in as her disciple.
