I don't know the unit at all.
A google search didn't do anything either. :-s
Anyway, maybe I guess you're speaking about a man covered in bear fur ?
If it is the case, no.
I need a classic big bear.
I mean, an Owlbear wouldn't fit, and it's much more similar to a bear than to a berserker with bear fur. :-D
I really need a big, natural, bear. No armor. No rider (unless, if taken off, it does still look ok).
