Argyle King
Legend
With the bear's arcane background and evolution from animal to magical beast to fully sentient creature, I think it would be interesting to do something thematically appropriate to that. Perhaps a Paladin or Cleric of Boccob? With the low Cha, Divine Grace wouldn't do you any favors if you went pally, but the attack bonus is better. His wisdom is potentially good enough to make for a decent enough secondary divine caster.
Fighter 2/Cleric 7 or Fighter 4/Cleric 5
Alternatively, is there some what to get him to qualify for the Warhulk PrC?
I like the previous proposal to have the bear go monk. It could be that he's trying to contemplate his existence and decide what he should do with his life now that he's not a normal bear anymore. ...or maybe he did that at first, but then decided he was better off embracing his nature and becoming a barbarian? Monk/Barbarian.... he wouldn't lose his already gained Monk abilities; he just wouldn't be able to take any more monk levels.
