Don't use the term "normal bear" as if any other bear other than a brown bear is abnormal. Just call the animal what is is.
Anyway, there are many situations when both species of bear get along fine with each other. Animals like elephants and dogs have been seen being friendly towards each other. Polar and brown bears would most likely be fine with each other since their similar.
Does Godzilla get along with Megalon?
If not, that would be a racist bear :)
By "normal bear" i mean a brown bear.
