|“||It's my world and it's all bisons in it!||”|
— Billy Bison, "Lady Krillers"
Billy Bison is the great-great-great grandson of Frederick Bison. He is condemned to live his whole life under "Bison's Law": whatever can go bison, will go bison.
He is apologetic and feels bad about people getting harmed by his "Bison's Law".
Billy has a fair complexion, black hair that resembles the horns of a bison and black eyes. He can be seen wearing a red T-shirt, blue jeans, and gray shoes. He also wears a brown backpack.
In "Lady Krillers", he apologizes for intruding on "today's episode" before being chased and ran over by a herd of bison.
“I'm real sorry about today's episode”
“I'm the great-great-great grandson of Frederick Bison. The originator of Bisons Law”
