Answer:
liger-75 % of victory
lion - 69% tiger- 68.77% or equal (unknown)
cougar-56%
black panther- 54 %
that's in my opinion, but still no one knows the right answer maybe it could be a liger or a lion or a tiger or even cougar and black panther, all i can say ...
god knows the answer.
But this is a matter of fact : [truth follows...]
there are no such kind of facts as tiger kills a lion in a fight, but there are some facts that tiger beats lion in a fight (but not as much as lion wins), and there are 2-3 or even more facts that lion has killed a tiger in a fight.
