badgers and wolverines.....very tough customers to be sure...I hear an adult male wolverine can take on a small bear
Wolverines routinely take on Cars. They lose, but often penetrate the radiator, leaving the driver and his vehicle out of action.
While we were pheasant hunting a couple years ago, my son stepped on something in the tall grass. It was a badger and it was not happy! The badger didn't back off but came after my son and got a grip on the cuff of his jeans, tripping him. My son bounced back off the ground and ran out of the grass with the badger hot on his trail. I fired a shot into the grass and the badger finally turned around and went away.
I can't imagine what a 200 lb. creature of that type would behave.
