Sometimes the bear would win, sometimes the gorilla. Being that gorillas are more evolved intellectually, if they were to live with bears, over time the gorillas would win all the time--they would use their strength along with their brains and problably use weapons to kill the bear. They are also superior climbers, so they would work from above and drop big branches and shit on the bear. You got to look at it realistically--the gorilla would definitely outsmart the bear!!!!
