I’ve just been reminded about the Sly Cooper games and how much I loved them! Figured I’d give making the titular character a go in Pathfinder. Haven’t put much thought into it beyond that, but for sake of argument let’s say PFS legal and see what happens!
Had some time to get a few thoughts down.
A raccoonish kitsune seems like the best racial choice. From there, rogue, ninja, or investigator look pretty good in terms of getting the right/enough skills and the appropriate style of combat. At that point, I think it comes down to the skills I want to invest in and what features I want.
Stealthy acrobatics was a big part of Sly’s skill set, as was disable device, and disguise.
Any ideas on how to get his weapon emulated in Pathfinder? It’s basically a shepherds crook, but ideally I’d be able to finesse it.
A hanbo is a walking stick or "half-staff"; a finessable, simple weapon in PF. If you want to do tricks with it it really should work with stick-fighting style though it isn't listed there.
I haven't ever seen the games though and I don't know what exactly you want emulated.
