Consider:

-High attack bonus
-Good hit points
-Excellent at stealth
-Favoured enemy bonus
-Track & TWF feats

I think these abilities make the Ranger a great thug/bandit. Even in the urban environment. If you want a Bounty Hunter, who could be better than an Evil Ranger with Human (or demi-human) as his Favoured Enemy? If you want a brawler (and Monks don't fit your campaign setting), try using a Ranger with Improved Unarmed Fighting. Consider using the Wilderness Lore skill in the "urban jungle".

A different take on an old favourite. Comments?
