Is a polar bear stronger and bigger and more vicious than any other bear?

Kind of, sort of. They are the largest species of bear in the world, for sure, but as far as being "stronger and more vicious" that depends on your point of view. Polar bears are just as dangerous as any other bear, and probably are a little stronger than most other bears.
