Neither! Lions and alligators do not live in the same area of the world so would never have such an encounter.
It depends on where the fight happens. On land the Lion is the superior opponent whereas in water the Alligator would win hands down. Depending on where the fight happens, either the lion or the alligator could win.
Well an American Bison weighs 2200 on average so it would be very difficult for an alligator to take one. If its the smaller European Bison than the Alligator could take it in the water. How ever on land any Bison would win against an Alligator.
