bear warrior sounds like a nice simple one, its been a plan of mine for a while.
Barbarian into bear warrior, take imp unarmed strike and improved grapple, stick with punching and grappling people till you turn into a giant bear, other feats into improving rage and possibly the feat that allows you to use strength to thrown weapons attack rolls for the throwing stuff at people if they fly etc.
A good rage overtakes me and I start ripping people apart class.
