Tiger vs Grizzly Bear
Quick answer
It is too close to call. The Tiger and the Grizzly Bear are evenly matched on paper, and in the wild the outcome would come down to size, surprise, and circumstance.
This is a hypothetical, educational comparison based on typical size, strength, and natural weaponry. In the wild these animals rarely meet, and most encounters end without a fight.

Ussuri taiga holds both species — tigers hunt boar and deer; bears fish salmon and raid kills. Real coexistence is documented, not just hypotheticals.
Siberian tigers and brown bears share Russian forests and occasionally kill each other. Tigers ambush with neck bites; bears rely on mass and swipes. Outcomes in the wild are mixed and depend on surprise and size.
