A polar bear would most likely win this fight. The polar bear, which is a much more beastly killer, could kill the grizzly bear with ease because it has a much larger size advantage.
Most likely a bear.
polar bears because they are the biggest and strongest bear and carnivore
I belive the scorpion would win. There are just too many wepons for the scorpion. The ability to hold its pray while it attacks is a big one.
