I think anyone turning up with an anthro-animal should probably be chased away (or maybe shot), damn furries...
Anyhow.
I reckon for sheer bashy factor the Ogre if you advanced him with Sav-Species progression would be a pretty worthy fighter or barbarian. Admittedly you wouldnt be starting at a full ogre's stats at level 4 (Im assuming your wanting to start around there with an ECL3?).
So he drools
So he's ugly
So he's a halfwit

But he hits stuff really, really hard and he's tough!
By the time you've finished lard-lad by level 6 he should be a pretty fearsome animal.
Well, thats what I reckon anyway.
