Who would win in a fight between an ox a black bear and a lion?

A lion because it can defend it self better then an ox and bear. The black bear will not win when the lion can kill it with a weight advantage and teeth, and also the ox can knock its chest with its thick head. This leaves the ox and the lion fighting. A lion has sharp claws and sharp teeth, while an ox has a thick, strong body, sharp horns, strong head, and large hooves. If the lion charged at the ox, the ox can hit it with its horns and kill it.
