"I CLAIM THIS WORLD AS MINE!"
-Ferocitus, Yin Yang Who?
Ferocitus is the newest Night Master. His only appearance is at the end of Yin Yang Who?.
History[]
Ferocitus is the newest Night Master, suceeding Eradicus. He broke into the Woo Foo Dojo and claimed the world as his. Unfortunately for him, Yin, Yang, and Yo were ready to fight and (much to Yo's relief) prevented him from saying who was the mother of the twins.
