As always, it is hard to compete with Barton Everest, but Indian Charlie certainly tries. If you can get him to to four bounty he becomes resistant to efforts to remove his Stud (although Sun in Yer Eyes still costs him bullets).
Ramping up his bounty also protects this "little guy" from getting hit with a shotgun - since you do not want to gift wrap ghost rock for your opponent like that.
otherwise, Charlie is pretty straightforward, and a good fit in Outlaw 2's - with Back Ways or maybe a Hostile Takeover
