I have a character type I've wanted to try for some time. Its a gunslinger/necromancer called Grimm West. I dont have much of a backstory worked out but I think Grimm West just has a cool ring to it. Only gotten into pathfinder in the last few months (And alas, I'm the GM of my group) but it seems quite possible but certainly not a optimal character.
Other then that I'd like to try an undead antipaladin/undead lord and the story would be the undead lord raised the antipaladin and is now using the corpse like a puppet/vessel.
