I'd like to see about three:
Nature's Reaper, this is an alternate class feature from D&D times. It's a druid obsessed with death and the natural cycle it is. He or she follows the autumn of all life and as such destroys those too weak to continue and siphons the life left in them. I would so love that kind of depth, this character practically writes itself, I think.
Religious extremist Knight in shining armor, yeah, I'm sorry I couldn't come up with a smaller title but it's mostly because English isn't my first language. This one is more of a tip of the hat towards Planescape: Torment and it's fantastic character Vhailor. I love me some references and this one would just knock my socks off.
Mordenkainen: I don't think I need to say more than: a tip of the hat to the original.
