In Pathfinder Adventure Path #34, things once again take a turn for the worse for our poor unlucky owlbear. It's one thing to be immortalized as a statue in the middle of a village, where children laugh at you and birds poop on you and you eventually become forgotten as part of the town square's mundane decor. It's quite another when the barbarians come to town and, in a sudden urge to show off their destructive power and strength, tear your statue down! At least the owlbear's ghost can take solace in the fact that those pesky barbarians are probably being equally destructive to the adventurers who got him into this fix in the first place.
Agreed - these barbarians are in for a world of hurt. As the "World's Unluckiest Owlbear" - i.e., the sufferer of repeated ignominious ends, this Owlbear will eventually become the planar herald of Zyphus.
