Master Yo

Master Yo is Yin and Yang's sensei as well as their father. He had taught the duo everything they know about Woofoo.

In his heyday, he was a hip and capable master of Woofoo. He had several arch-foes, such as Kraggler. Now a days, he's a lazy, grumpy old panda who prefers to spend his days doing absolutely nothing. He is also money grubbing and is a bit of a pervert. He can also be easily distracted by food.
