I do not remember a double bear, but maybe the Yao Guai from Fallout?

I mean, given that the scientific name of the brown bear--Ursus arctos--literally translates to "bear bear" (first from the Latin, then the Greek), that seems sufficiently like a "double bear" to me.
And of course, the Eurasian Brown Bear--Ursus arctos arctos--becomes the dreaded "triple bear," with a much higher CR.
So, like, is there an anti-bear in D&D?
I might have had that exact post in mind when I commented.
