Master Yo is the deuteragonist of Yin Yang Yo!. He is the father and teacher of Yin and Yang. He claims to be the last Panda alive. Although his current age is unidentified, it is known that he missed his 117th high school reunion making him a centenarian.
Master Yo is a black and white Panda, with purple eyes and a grey Nose. He mostly wears a blue-green Belt. In his younger days, Yo had an afro, and wore a purple sash with studded wrist bands. As Possum Panda, Yo wears a possum outfit, consisting of pink gloves, shoes, belt & tail, with a black mask. He even wore spandex as a former member of the currently disbanded rock band Pandangerous.
Though incredibly wise, Yo is crude, lazy, flatulent and gluttonous; in addition, he is neglectful and abusive, though he does care about Yang and Yin. In Bad Nanny Jamma he shows that he is willing to put his duties first, but just because he had nothing better to do, and in Deja Foo he stood in front of Yin in order to protect her from the The Night Mooster's attack, although his sacrifice was unsuccessful, as they were both destroyed. He is offended by the stereotype of Woo Foo Pandas being fat and stupid, as shown in Unmoving Pictures. Yo is also insulted by the misconception that Pandas are related to Raccoons. Master Yo also believes that Ha-Woo-Chris-Foo-Nah-Kah-Mas, a Woo Foo holiday that celebrates Woo Foo history, should be celebrated correctly, by those who actually practice Woo Foo. He feels that others who see the season as a time to get toys is a perversion of the holiday spirit. He loves soft pretzels and can be easily distracted by food in general.
Master Yo was a very powerful Woo Foo warrior even at the age of three, being able to perform many advanced techniques.
As revealed in Worked Stiff, he was adopted and raised by Ti and Chai as their student and son-figure. A hundred years ago Master Yo defeated the Night Master's army by turning it into stone; however, the Night Master used the Amnesulet and made the entire world forget this. In his younger days, he was in the band called Pandangerous; ironically, they didn't play well, so they used Laladins Amp to hypnotize their audience. In a flashback in the episode The Big Payback, he is shown telling the other band members that their music sucks. He eventually got to have a son and a daughter, but had his memory wiped, thus neither he or his kids remember they are related. As he reached old age, he planned to retire; but, he was visited by the spirits of Wooda, Shooda, Chai, Ti, telling him to train two new Woo Foo warriors: Yin and Yang. He got them to train Woo-Foo by giving them a coupon. He also has goes by an alter ego, known as Possum Panda".
- Yin and Yang - Yo is Yin and Yang's master and biological father (somehow). Despite his unorthodox teaching style and often poor parenting, he cares about his students deeply and is not afraid to be hard on them when he needs to be. When he was revealed to be their father, the two were shocked to learn this but happy it was him and wasted no time in calling him their father, though they question who their mother was as he was too nervous to tell.
- Ti and Chai - As revealed in "Worked Stiff", Yo was adopted and raised by Ti and Chai as an infant as their apprentice and son-figure; however, just as an adult Yo is to Yin and Yang, Ti and Chai were poor parents to him and forced difficult tasks upon him, even in his young age.
- Kraggler - A young Yo faced and Kraggler many years ago; fter their battle, Yo and Kraggler have maintained a rather mutual friendship while still retaining a rivalry.
- Boopy Van Ha-Ha Pants - Yo's arch-rival in Clown-Fu.
- Giraffe, Hippo, and Squid Girls - The three were Yo's ex-girlfriends who he owed them his end of the bargain until he lost his memory to the Night Master while the girls developed a grudge against him and worked together to kill him until they decide to join him on a date that he falls asleep at. In "The Pecking Order", he flirted with the squid girl.
- Edna - Yo pursued a relationship with Edna under the influence of the Brooch of Iresistability. The wedding ring he was going to give her was stolen by Yin and Yang who led them to Carl's palace where they were fused, disgusting them so Yin was able to blast of the Brooch; however, Edna retains feelings for him.
- Yuck - A combination of Yin and Yang, Yo would be arguably considered his father.
Yin & Yang
Master Yo is Yin and Yang's master and father just as they are his son and daughter (for some unexplainable reason); even though he is a little irresponsible, he does care about them and shows it on certain episodes before Yin, Yang Who?
In Deja Foo, when the Night Mooster was going to destroy Yin he actually stood in front of her.
In Family Day, he gave them a gift even though thinking they are not really family and at the end of the episode he received a gift as well from Yin and Yang.
Also, in Fit to be Tried when The Mighty Justice Orb said he'd remove Yin and Yang's Woo Foo Powers Master Yo said he didn't want to find two new students; he does think well of them, even if they overstress him.
The Return of the Night Master: he bought three tickets for the finale after seeing how disappointed they were.
Family Day: he got them a gift even though he still didn't know they are really family.
Voyage to the Center of the Yo: at the end of the episode, he states they make him proud.
Season's Beatings: he treated them considerably nicer compared to other episodes.
Deja Foo: the most parent-children love in the whole series. When The Night Mooster attempted to kill Yin, he stood in the middle; however, the result was the demise of both Yin and Yo.
Brain Drain: When Master Yo was about to attack Mastermind, the villain told him to stop or he'll "rub Yin's head really, really hard with his giant thumb." Master Yo looked terrified and cried "Don't! She gets rub burns easily!"
How they met
It is shown in Yin, Yang...Who? that Master Yo is actually Yin and Yang's father (though this is genetically impossible), but had his memory wiped so he could train them without parental worry.
It was always thought they just met because of the coupons given to them, and Yin and Yang were orphaned street urchins; though it may have been the hand of fate or the Spirits of the Woo Foo Elders that led to him using two coupons and going right to them.
As a young adult and to a lesser extent, his current age, Yo has displayed super strength, super speed, agility, flexibility, and durability.
As a Woo Foo master, Yo has mastered all of Yin and Yang's techniques and many more. He is also a master of Clown-Fu.
